It is difficult to overestimate the significance of the deep pump in the water supply system of the country house, especially if the well is the only source of water. Competent selection and high-quality installation of a water supply device allow a long time and uninterrupted to use the offline system.
Excellent assistant for residents of countryside, dachens and country house owners often become the deep pumps of the Aquarius from the company "Proelectro". A wide model range allows you to select a pump corresponding to specific operating conditions, and the increased performance and adequate price of the equipment make waterproof pumps in demand among buyers.
Deep Pumps Aquarius - Balance Prices and Quality
Submersible pumps "Aquarius" manufactures the Kharkiv company "Proelectro" since 1996. The company produces a whole series of household electric pumps with a rise in lifting up to 200 meters and with a capacity of up to 12m3 / hour. Technical and operational characteristics allow the use of deep equipment for pumping water from sandy and artesian wells.
Among the advantages of Aquarius pumps can be attributed:
The price of the pump of deep aquarium depends on its technical characteristics and ranges from 7500 to 17500 rubles.
Aquarius's deep pumps correspond to the International IEC 335-1 Security Standard and in terms of quality levels are not inferior to similar borehole pumps of European brands Grundfos, Calpeda and Pedrollo. Among the manufacturers of the CIS countries in quality, pricing politics, design, demand and reliability, water pumps have no analogues.
Device and principle of operation of the deep pump of aquarius
Consider the Device of the Deep Pump Aquarius. The electric pump consists of a multistage pumping part, an electric motor and a remote condenser box.
The electric motor is filled with oil and consists of a rotor, stator and rotating ball bearings.
The pumping portion is represented by a monolithic unit in which the bladeless taps, workers and guide wheels are located, as well as the drive shaft. The cover with the inner tube thread fixes all the details on the spot. In the lid there are holes for fastening equipment with a cable.
The diameter of the impeller determines the pump performance - the volume of water that the pump can raise for a certain period of time
The cover with the inner tube thread fixes all the details on the spot. In the lid there are two holes for fastening equipment with a cable.
In the condenser box there are a power cord and capacitors that provide the operation of the electric pump.
In the pumps, Aquarius uses reliable German automation, protecting the equipment during critical modes of operation. A remote control device is attached to the power cord.
The principle of action of the depth pump of the centrifugal type is as follows. As a result of the rotation of the impeller, kinetic energy is formed, which is transmitted to the blades and affects particles of substance, that is, water. The liquid in the area of \u200b\u200bthe impeller rises into the upper part of the pump housing, and the new - under pressure enters its place. Water transition is maintained by constantly rotating wheels.
Borehole Pumps Aquarius: Models and their characteristics

Installing and connecting Aquarius pump
When installing BPTSE Aquarius, it is necessary to take into account some general recommendations on the installation and operation of submersible pumps:
- The remote condenser box should be located under a canopy or indoor.
- During operation, the pump must be completely immersed in water.
- The distance from the pump to the bottom of the well - at least 40 cm.
- The first turning on the electric pump can be made no earlier than 5-10 minutes after the full immersion of the equipment into water.
Consider the phased process of installing and connecting the pump of Aquarius:
Gently omitting the electric pump in the water, holding the cable and pipeline. It is necessary to control that the power cord has not experienced tension.
Before turning on the pump, you must make sure of its full immersion in the water
Service of the deep pump
The deep pumps of the Aquarius are designed for a long service period, and the uninterrupted operation is already dependent on the user itself. Compliance with the rules of operation and periodic inspection - a guarantee that the pump will work for many years.
Once every two years, the pump must be pulled out of the mine and inspect. It is necessary to raise the unit as much as possible, so as not to break the flask of the pump wall. The extracted pump is checked for cracks and chips. The appearance of such defects can lead to water expansion during the freezing of the source.
The axis of the engine must rotate smoothly and easily. If the motor shaft scrolls with difficulty, the bearing replacement is necessary. If necessary, it is necessary to add oil and the gland. Engine winding should be examined on overheating traces.
Disassembly of the deep pump of the Aquarius must be taken carefully - the insulation of the cable becomes fragile with time and it can be easily damaging
At reduced pressure, it is necessary to change the working wheels - most likely they were worn out. This work is better to entrust specialists.
Possible breakdowns of the pump and the order of their elimination
Consider possible malfunctions, causes and order of their elimination.
The pump is not included in the work.
Possible causes and elimination:
Reduced pump performance.
- pipeline break and fastening fault - raise the pump and check the integrity of the pipeline, eliminate defects;
- holes of filters beat - raise the pump and clean the filters;
- a sharp voltage drop - to ensure normal voltage - 220V.
The protective device is triggered after short-term work.
We will analyze the phased repair of the deep pump of the Aquarius if the unit is clogged:
- Remove the protective grid. If it is attached to a special clamp, then you need to press a little in the middle and pry a screwdriver. On some models, the grid is attached by two ordinary screws that just unscrewed.
- Remove the cable channel - a metal chute that protects the cable from damage. This element is present in wide pump models.
- Separate the pumping part from the engine - unscrew the four bolts by the 10 bolts and remove the plastic clutches.
- The disassembled design is neatly putting on a horizontal surface.
- Turn the shaft to the end key, holding the upper part of the device.
- Wash the pump thoroughly and collect it back.
How to choose the Aquarius Pump
The right choice of pump is the key to its long-term work. When choosing the optimal model, it is necessary to take into account the characteristics of the well and comply with some conditions:
- the flow rate must exceed the performance of the pump, since over time the debit of the source decreases due to the grain;
- determine the required pressure headband based on the distance from the water intake point to the hydroaccumulator and the pressure loss on the horizontal portion of the pipeline.
According to the schedule of pressure characteristics, you can define a suitable model of equipment.
Drilling well in itself does not even mean a complete solution to a water supply problem at home. Even if it was very lucky, and the good artesian well has a certain pressure of water raising it to the surface, it is clearly not enough for the functioning of the autonomous water supply system. In addition, the waterpover pressure should ensure the passage of fluid on all vertical and horizontal communication sites, it is necessary to create its mandatory reserve at least 2.5 atmospheres to ensure that all household appliances (water heaters, boilers, washing and dishwashers, etc. .) Worked correctly. Be that as it may, do not do without pump.
Before choosing a pump for a well, you need to get a certain idea of \u200b\u200bthe diversity of similar techniques, its construction and operational features, the criteria for assessing the models offered on sale. It will be hurt to acquire a pump, which simply will not cope with the responsibilities assigned to it. Probably no less unpleasant situation when it is purchased absolutely unnecessary "Focused" model, the functionality of which remains simply unclaimed. And in that, and in another case it is in vain the money spent. In short, the store needs to be sent with a clear idea, which pump will be optimal in a specific situation.
To begin with, it is worth understanding what borehole pumps are. First of allThey can be divided into two large groups - superficial and submersible.
Surface pumps
The name itself speaks for itself - such an installation for pumping water is installed outside the well, on the surface of the Earth, and is connected to water horizon with pipes or flexible sleeves.
It would seem that there would be a lot more advantage in such a scheme - the mechanisms are always in sight, it is easy to control and periodic maintenance, there is no need to stretch long power cables to the place of water intake, worrying about the quality of insulation of wires. Installations - under the supervision or located in lockable rooms, that is, significantly reduced the likelihood of their embassy attackers.
However, the surface layout of the installation of tatt and a lot of flaws. First of all, it is significantly more modest indicators on the water being created - they are simply incomparable with similar parameters. In addition, the factor of noise cannot be excluded - the installation of pumping equipment in the house will most likely require a separate room.
What types of pumps can be attributed to the category of superficial:
Manual pumps
Mention of familiar all since childhood hand-held speakers, probably, many will cause a smile, and meanwhile they still actively apply and, for sure, they still have a future. Not in all situations need a constant flow of water - there is enough possibility of its one-time set (for example, the points of collective use are in settlements, garden partnerships, garages, etc.). It is for such cases that manual pumps are served by extreme simplicity and reliability.
Manual column - such pumps still have not lost relevance Their working circuit is simple - piston, cylinder and two valves, air and water, working in antiphase. The muscular effort through the lever is transmitted to the suction mechanism, which allows you to type the desired amount of water.
No dependence on the source of energy is often the only possible option for organizing irrigation on country garden sites where the power supply has not yet been carried out. It is only necessary to drill not a particularly deep and time-consuming Abyssinian well. Install such a column - and the question will be resolved. Often, this is also installed in a common system with an electric, through a tee, with the possibility of switching as needed - there will always be a backup source of water during problems with power supply.
The manual column can be mounted directly on the well (in the case of the Abyssinian Well), or have a pipe descending into the thickness of the water horizon.
Self-priming surface pumps
All other pumps considered in this publication will be with an electric drive. In fairness, it can be noted that there are also pumping units with a power plant based on internal combustion engines, so-called motor-pumps, but they do not have, most often, expressed domestic use.
So, consideration of the familysurface Electrical pumpswhich are designed to fence water from the well, it is worth starting with the simplest self-priming systems.
The case of such pumps never enters into external contact with water and does not need special protection, which greatly simplifies their design. With the source of water, they are connected by sleeves or stationary laid pipes, while the prerequisite is the presence of the check valve - they simply cannot cope with the task.
The cooling systems of the drive on them is not provided, and this is their vulnerable place - the probability of overheating is large when overwhelming. The design does not have special difficulties, control mechanisms and control - only inclusion and engine shutdown. Thus, an additional equipment will inevitably need additional equipment for the organization of automatic control over the operation of the plumbing system.
Similar pumps do not differ high operational indicators. The average level of water generated by the water does not exceed 8 ÷ 10 meters, which is clearly not enough to organize a home water supply network. At best, they can be applied to the simplest home water system - with the filling of the accumulative container installed in the upper part of the building, from which water goes to the distribution points non-per-on, gravity.
In short, it is, although inexpensive, but far from the best option for me to provide a residential building with water. The scope of application of such pumps in the conditions of private household, rather, the organization of the temporary irrigation system of the area from the well or natural reservoir.
Home pumping stations
This technique is already much more serious, as it is adapted to the tasks of organizing autonomous water supply in a residential building. In addition to self-primingpump Station is necessarily equipped hydroaccumulator - a membrane tank of a certain container that will constantly maintain the required pressure in the home water supply network.
Based on this, the overall design of such stations includes control devices and control mechanisms, including a drive when the pressure drops in the system to replenish the water reserve, and turn off the power to achieve the required level of pressure.
The main problems still remain unresolved - high noise and insufficient performance of the pump part of the station, which does not allow to lift water from considerable depths - use is limited to a fence from Abyssinian or sand wells to a depth of 10 meters.
More modern models are produced, with fully electronic control and the ability to program some operational parameters. Such pumping stations can be enclosed in the polymer case, which partly solves the problems of increased noise and vibration.
Pumping stations with ejector (injector)
And what if it still requires the installation of the surface pump, but the depth of water intake is from 10 to 25 meters? There is a way out - in this case, self-priming pumping stations equipped with an ejector (external) or injector (built-in) mechanism will help.
In this case, an additional water circuit was formed in the water intake system with a smaller pipe, along which the liquid is pumped at high speed. The vacuum generated by it in the ejector creates additional pressure in the main intake tube.
This leads to an increase in pressure - such installations can work at considerable depths. True, it leads to a general decrease in the performance of the pump itself, since part of the water is sent back for circulation by ejector contour. But the "golden middle", arranging and created by the water post, and the performance, still often you can choose.
Another big minus - such even more noisy than ordinary self-priming, that is, you will definitely require soundproofed premises.
If this option is unacceptable, nothing else remains, except to choose a pump for a reward well.

Submersible pumps
The main feature of such pumps is already stipulated in their name - they are always located in the thickness of the water (in the well or in the well) and are connected to the water treatment system of pipes and hoses. Power supply is supplied to them by means of a long well-insulated cable.
The scheme of their installation predetermines and their characteristic design features. They always have a reliable waterproof metal case, performed from corrosion-resistant alloys, with efficient waterproofing of details and nodes. Be sure to have a hook device, for fastening the safety cable, on which the pump is lowered to the water intake.
The overwhelming majority of pumps are equipped with built-in filters (grids) eliminating entering the mechanism and in solid suspension pipes are invalid for this size model. Many pumps, in addition, have a built-in return valve, which significantly simplifies its installation into the home water supply system. If it is not, then a special threaded connection is usually provided to install the valve device.
The benefits of submersible pumps have a lot. These include:
- Feedlessness of work - sound oscillations are quenched by a layer of water.
- Such mechanisms are not afraid of thermal drops or freezing - the same temperature is almost always supported in the aquifer of the well.
- At the same time, they are not afraid of overheating - the water is pumped through them effectively cools working nodes.
- Such pumps are much higher and the pressure created. Some models of submersible pumps (deep) are capable of lifting water to a height of 100 or more meters.
The shortcomings are as follows:
- Certain difficulties with the installation of such equipment, often requiring the involvement of specialists.
- The need for laying a high-quality safe power line, sometimes for quite considerable distances.
- Difficulties with control over the work of the equipment, with preventive or repair work, requiring each time the pump extraction from the well.
The overwhelming majority has a characteristic cylindrical shape, representing a metal column height from half a meter to 2, 5 M.. But according to the principle of operation, they can differ significantly.
Vibrating submersible pumps
Uncomplicated by its design, reliable, inexpensive, these pumps won very wide popularity among country house owners. Large productivity "boast" they cannot, but for household and garden needs it is often quite enough.
The principle of work is as follows. The electric current, passing through the winding of the coil, causes a periodic, with a certain frequency, attracting an anchor with which the membrane (diaphragm) and piston is connected through the rod. The rapid return-translational movements of this mechanism create a vacuum in the working cylinder, and water through the valve system is absorbed from the well into the pump itself and is transmitted through the outlet nozzle to consumption points. The absence of rotating nodes predetermines the high mechanical reliability of the pump, and the ease of electroschemes, fully filled with a waterproof compound, guarantees its long-lasting trouble-free and safe operation.
Some models of vibration pumps are capable of creating a water column 20 and even more than a meter. The pump is easy, it is quite possible to lower in the well even on the Kronov cord. Energy consumption is minimal. Everything is — pronounced advantages Such devices
Disadvantages of such mechanisms are available, and very significant. Such pumps are sufficiently noisy, but the main thing is that the vibration waves created by them are capable of leading to the destruction of the wellbore or the erosion of the clay bottom and the walls, quite quickly catching the aquifer. Apply similar pumps is recommended exclusively in sand wells, with certain precautionary measures, in order to prevent excessive stamps of water and enter the sand in the water intake holes. Ideally, they are more suitable for wells dressed in concrete rings, and for the well will be wiserfully choosing a pump of a different principle of action.

Centrifugal submersible pumps
The most common borehole pumps are centrifugal. They are a cylinder with placed inside the electric drive. On the axis of the engine's rotor, a wing turbine is installed, which rotates in the working chamber having a peculiar form of "snail", with a feeding nozzle in the center and output - on the periphery.
The rapid rotation of the turbine causes the operation of the centrifugal forces, which discard the flow of the incoming water (in the diagram is shown by green arrows) from the center to the walls of the working chamber.
As a result, a significant difference in pressure is created - from discharge in the area of \u200b\u200bthe axis of rotation (blue area) to elevated - to the edges of the blades (in the figure - a gradual transition to red). It provides a constant inflow of water from the feed pipe, and the desired pressure at the output.
Such a work scheme is also used in most surface pumps, but the required output pressure parameters can be achieved by increasing the diameter of the working chamber. In the borehole pumps, where the sizes are strictly limited, this question is solved otherwise. The achievement of high water column indicators occurs by serial installation on one axis of the drive of multiple cameras.
The water pressure created by one camera is a kind of "support" for subsequent - and so on. As a result, the output pressure folds from the total effort of all working wheels.
The number of working cameras predetermines the total height of the "column" of the pump The number of cameras can be different - from two to three and even up to several dozen - this predetermines the height of the "column" of the submersible well pump and its operational characteristics.
This scheme fully justifies itself - such pumps are capable of lifting water from very large depths. Their advantages should also include silent work, lack of significant vibrations, a wide choice in a large range of water column and performance.
The main disadvantages are the complexity of the installation, especially in the deep wells, the need for quite frequent maintenance, considerable cost.

Screw pumps
Screw-type borehole pumps are not widespread, but, nevertheless, are available.
The working part of them consists of two main details.
On the shaft of the electric drive eccentric rotor of a complex spiral-shaped form. It rotates in the cavity of the stator, which also has a complex geometry with one or two windows of the spiral. The stator body is usually performed from the elastomer - rubber, which ensures the dense fit of rotary loops. Thus, a certain amount of cavities filled with water is always present in the working cylinder of the pump. When rotating the screw PR scores these volumes from the inlet nozzle to the output. The total volume of fluid in the cylinder never changes, which allows maintaining an even stable waterproof pressure.
Such pumps easily coped even with fluids of high viscosity, which predetermines them prevalence in production conditions. However, there are also models for water lifting from wells.
The scheme of such pumps is effective - they are able to lift water from considerable depths, about 40 — 50 meters. However, the presence of high friction units quickly leads to their wear, which requires regular maintenance with the substitution of parts. What is quite acceptable and justified in production conditions will bring a lot of trouble with private use of such equipment.
Vortex pumps
Another scheme, which is used in superficial, and in submersible pumps. The special shape of the wheel creates not only centrifugal acceleration of the pumped ox, but also a powerful turbulent flow, a significantly increases the output pressure.
The advantages of such a scheme are high performance, low-noise, relative simplicity of the device, which predetermines and lower price compared to centrifugal of the same power.
Pumps are not afraid of "convulsion" - in principle, they can be used even for pumping gas-liquid dispersions.
However, substantial disadvantages are small durability and special requirements for purity of water purple, seriously limit the widespread use of vortex pumps - they are clearly losing the centrifugal.

What criteria are guided by the selection of the pump
So, what parameters, in addition to the principal scheme of the pump, should be assessed when it is selected:
- Power supply and power consumption. If everything is clear with the first value - as a rule, all the borehole pumps of the household level are powered from 220 V, then with the power of the question is special, as it corresponds to the existing power supply capabilities installed by the reinforcement (automata, Uzo.) and cable part. Important addition - some pumps (in particular, centrifugal) Do not like voltage drops, therefore, it may be necessary to need an additional installation of the stabilizer.
- The maximum pressure (the height of the water column) - the parameter is mandatory will be specified in the technical documentation of the product .. This value says not only about the possibility of raising water from a certain depth - water should be pumped through a system of domestic water pipes, download it into a hydroaccumulator or create the necessary excessive redundant Pressure and have even 10% reserve. This question should be considered more.
There are special
If you want to have free water in any quantity on your own section, then you should start with the mine drilling to the aquifer. The second step will be the installation of a deep pump in the well. It is the good work of such equipment that will guarantee high-quality watering of garden plants, the continuous functioning of washing and dishwasher, a bathroom and a bathroom.
Depths for wells have different power, sizes and other parameters. In this article we will look at the main selection criteria. The installation of optimal equipment will save you from a variety of problems in the future and will give confidence in the constant present of H 2 o on your site.
General provisions
In order to successfully pump water from wells, wells or other water bodies, there are the following types of pumps:
- Self-priming. Such equipment is installed on the surface and sometimes has the form of a full-fledged pumping station. It is not bad to cope with sandy wells that have a relatively small depth.
- Submersible. They have a greater power, the volume of the bought fluid and the height of the pressure pole. Constructively able to penetrate even very narrow mines. Ideal for artesian wells.
Selection and installation
Since the deep hole for the wells is suitable in the best way, let us turn to the rules of its choice. To do this, first of all, it should be determined where water supply is required and in what quantity.
Right criteria
- Pump performance. The amount of fluid that it can overtake for one hour.
- Height of the pressure. The strength of the fluid is selected in accordance with the depth of the mine and its remoteness from the house.
- Debit well. The real volume of water, which can be provided with aquifer for an hour of continuous supply.
In this regard, you should proceed to the choice of pumping equipment after you are finished to drill well and provide a technical passport with all the necessary data.
It should be indicated in it:
- Shakhty diameter. From what will depend on the diameter of the immersed apparatus.
- Static and dynamic water levels. The first is formed in the event of downtime, and the second - with its active use.
- Productive wells, which are measured by the amount of transmitted cubic meters of fluid within an hour.
- Depth mine. Sometimes affects the required height of the pressure.
To acquire a too powerful submersible pump for two reasons:
- Its price will be much higher, why overpay?
- If its performance is more productivity of the well, then it will not have time to fill with water. What follows the work of the "dry" stroke, which, in the absence of special protection, will lead to engine burnout.
Thus, we now know that the maximum power should not exceed the amount of water inflow. What affects the minimum?
Let's consider:
- The size of your family. On an adult, an average is required about 1000 liters per day. Multiply this number to the number of permanent tenants, and you will know the daily need of your home in the water.
- The presence and area of \u200b\u200bthe garden. On watering plant crops usually takes up to 2000 liters of the necessary fluid.
- The number of simultaneously used consumption points.
Here are their approximate list with a regulatory consumption measured in m 3 / hour:
- washing - 0.7;
- bathroom - 1.2;
- bidet - 0.3;
- shower - 0.8;
- machine for washing dishes - 0.6;
- racket - 0.3;
- washing machine - 0.8;
- bathroom - 0,4.
So, to start the washing machine and fill the bath at the same time, equipment with a productivity of at least 2000 m 3 / hour. But, do not forget that the need may arise at this time and wash the dishes and go to the toilet.
In addition to the power that we choose based on the capabilities of the well and the needs of tenants, it is also important to choose the correct height of the pressure on which the fluid supply will be required.
Calculations perform as follows:
- We take the height of the house and add 6 meters to it.
- The resulting amount is multiplied by the loss of pressure force in the process of moving through the pipeline. It is 1.15.
- Now add the depth of the mine to the surface of the water mirror. We take this magnitude from the technical passport provided by the drill company.
- Next should be taken into account the distance of the well from the building in need of water supply. It is believed that 10 m horizontally equals 1 m vertically.
Suppose that the height of your house is 7 m, the depth of the mine is 30 m, and the remoteness from the points of water intake is 20 m. We substitute: (7 + 6) * 1,15 + 30 + 2 \u003d 46.95. That is, the pump is required, the height of the pressure of which is at least 47 m.
The most important is considered to be just the calculation of water supply height than the power of the pump. Since it is rare when all the points of water consumption are open, but the appearance of pressure can lead to the complete absence of H 2 o in the water supply system.
Tip: If an error is able to calculate the equipment performance, it is recommended to install a membrane tank.
Using it, it will be possible to set the pressure level, which will avoid the hydrowards along with frequent inclusions and engine shutdowns.
Installation
How to install a deep pump in the well? To do this, it will take the device itself, a metal-plastic pipe of the required length, adapter, steel cable and an electrical cable with waterproofing.
Installation instructions look like this:
- We screw the special nipple on the pump outlet, sealing the connection using the "winding". It will serve as an adapter on the threads of the casing.
- Polyethylene tube before fixing as much as possible in their own hands. This will allow you to lower the device most.
- Connect the power cable. In this case, it is necessary to provide waterproofing as possible using a special corrugation or shrink tubes.
Tip: When buying equipment immediately check the presence of the wire.
Because it is usually not included in the package and therefore it should be purchased separately.
- We bind the steel cable to the briefs specially intended for this, located on the pump housing. From above, it can be attached to the winch installed on a tripod. This will facilitate the immersion of the apparatus for a large depth and will immediately answer the question of how to get the deep pump from the well for maintenance.
- Now the pipe, the cable and cable tightly connect with each other with special clamps so that one whole track is turned out.
- Lower the unit. Places where it is clinging behind the walls, carefully overcome the rotational movements.
- Fix the position of the pump below the dynamic level of water, but at a height of at least a meter from the bottom. This will prevent suction to the sand and other small particles.
- From above, we set the knee, the guide of the pipe towards the house and tightly close the mine to prevent oxygen and atmospheric precipitation from entering it, which contribute to the corrosion process.
- To the building they pump the trench depth below the soil freezing. Depending on the region, it may vary from fifty centimeters to one and a half meters.
- Connect to the system of the water supply system at home and use clean and free water from the well.
The presence in the country area or in a private house of autonomous water supply is a huge plus in their arrangement. The owner does not depend on pumping stations - it has its own. There are many installations for pumping water: superficial, deep pumps for wells. If you are overcome by doubts which you choose, see how the installation is made with your own hands (installation on the example of the pump of Grundfos).

The main function of the deep pump is to extract the aqueous mass from the bowels of the earth and transporting it to the consumer in residential premises or household buildings (kitchen, shower, toilet). Also, it is also possible to water or greenhouses, and filling backup containers.
Depth pumps have a small cylindrical body. They practically do not occupy a place on the plot. There are 2 types of pumps such:
- Industrial. Used by enterprises. Due to high power, can lift water from a depth of 100 meters. Have impressive dimensions.
- Household. Used in private homes or cottage sites, can be installed on their own, differ in compactness and relatively high power.
Council. Before installing, consult with experts. The power of the chosen pump will depend on the depth of water.
Also, the pumps differ in the method of their installation.
- Submersible pump. The device is completely immersed in water, the pressure hose is given from it, which is performed with a plumbing connection.
- Surface pump. The device is located outside the water surface, 2 hoses are given: pressure pressure (performs water supply to the plumbing) and suction (provides fluid absorption into the pump unit).
In addition to the range of application and the installation scheme of pumps, there is still a classification of the design and the principle of operation:
Centrifugal pumps. Used at any time of the year. A hydraulic mechanism is used. Water supply is carried out due to the rotation of the wheels located near the engine. The working part (wheels) is made of dense plastic or stainless steel, which provides small design. Resistant to abrasives (sand and clay). The installation of this equipment provides for the presence of a coarse water purification filter from sand and stones particles. It is cooled with the help of the water passing through the body, therefore it is set according to the principle of deepening. Such pumps are equipped with a temperature sensor that automatically turns off the device in case of its overheating. The only disadvantage of the equipment is the high cost, compared with Vortex.
Council. If it is planned for year-round accommodation in the country house, it is better to choose a centrifugal pump.
Vortex or vibratory pumps. Such equipment is not intended to supply a large amount of water. They are used only in shallow wells. Designed for seasonal water consumption. The operation of the mechanism is carried out at the expense of high-frequency oscillations leading in motion the mechanical piston, which ensures the absorption of water into the apparatus. The advantages of this kind of equipment are low cost, compactness of dimensions, minimal energy consumption. Cons - destroys the walls of the well due to prolonged vibration effects, low power and low performance.
Council. To the vortex pump did not destroy the walls of the well, when it is installed on the housing, rubber rings are put on.
Device of the Pump Unit of the Depth
In order to correctly perform the installation of pumping equipment, you need to know which pump from which it consists of how is going and working.
The main parts of the device is the engine and pumping part. At the bottom of the housing is the engine, when installing, special attention is paid to its waterproofing. The pumping part is a multi-stage mechanism, which includes working wheels, paddle taps and actually drive them into action.
The product is cooled using a repulsive water. Outdoor cooling occurs due to the passage of water masses between the pump housing and well walls. Internal - when passing water directly through the unit.
Important! If the installation of the pump unit on the bottom or walls of the bored well is not possible, the well is equipped with tubes from asbestos.
Among all the water pumping devices, the depth pumps are most popular. They have several advantages over other aggregates:
- silent work;
- no interruptions in the supply of water mass;
- easy and fast installation;
- water fence at great depth;
- narrow cylindrical shape of the case;
- protection against engine overheat;
- made of anti-corrosion materials.
Council. In order to choose any pump, it is necessary to take into account the shape and depth of the well. Subsequently, you will not spend time, strength and funds for installing additional equipment.
In order to properly select the deep pump, you must consider the following data:
- water consumption at every point of water intake and on the whole site in the amount;
- diameter and depth of a borehole;
- geological data of the land plot (type of soil, depth of groundwater and so on.);
- the presence on the site of sources of electricity supply.
The pump selection directly depends on the depth of the well and the occurrence of groundwater. If the aquifer is at a depth of 10 m, then it is worth choosing a deep pump. When purchasing a pump, choose a device with a slightly exceeding the required: Subsequently, you can enhance the water supply, without resorting to replacing the water replacement device.
How the pumping device depends on the depth of the well
To select the pump, it is necessary to see the wells of the wells, all its parameters are indicated. If you do not know the depth of the well, then it is necessary to make measurements. To the dry (!!!) rope to bind the ship and lower it into the hole, remove the rope and the wet mark determine the distance from the surface of the Earth to the water level in the well. Omitting the rope is deeper, you can determine the depth of the well.
By purchasing the pump, be sure to learn the instructions and passport of the product. These documents indicate the power of the pump depending on the depth of the well.
- 30-60 meters. Installation of pumps in such conditions is performed directly in the well. When installing additionally put 2 -3 check valves, so that the raised water does not leave back. In such wells, centrifugal pumps equipped with thermal protection are installed. The device using special equipment is introduced into the well and fixes the cable on the ground surface.
- 10-20 meters. When watering water on medium and small depths, a surface, not a deep pump can be used. Such a device is installed away from the source, and the water is taken from the hose from it.
Installation of a deep apparatus on the example of the submersible pump of Grundfos (GRANTFOS)
Grandfos (Grundfos) depth pumps are equipped with submersible engines. The silent operation of the engine is ensured due to the installed sliding bearings, lubricated with a special liquid anti-corrosion lubricant. The electrical part of the pump is filled with a liquid, the marginal measurement temperature of which is -20 ° C and below. So that the engine worked properly, it is necessary to constantly monitor the level of fluid flow in it. Topping recommended Liquid type SML-2 only Grunfos. For the fill to the electric motor, use the following algorithm:
- Make sure that the engine installation is made in a vertical position with a deviation of 10-12 °.
- Unscrew the plug with a screwdriver.
- Using the syringe, fill the liquid into the engine.
- Distribute the liquid evenly on the surface of the engine capsule by sinking the device, the audience will come to the surface.
- Tighten the threaded plug as a tight as possible to prevent spraying.
- Install the engine into the pump housing.
In order for the pump engine to cool freely, it is necessary to control the temperature of the fluid flexible and the minimum value of the water flow rate. To ensure free convection, the well pipe width is made by 4-6 cm larger than the diameter of the pump housing.
Important! Free convection of the engine is not allowed under the formation of deposits on the pump housing.
Before making the pump mounting, you must make sure that it is disconnected from the network after possible verification and its inclusion is excluded. All the technical data of the products are described in the passport in the form of a table, the power, electricity consumption, power supply voltage of the "cosine fi", etc. are demolished.
Grudfos pumps (GRANDFOS) are equipped with an internal thermal relay, which is triggered when the installation is overheated, turning off the power of the pump. In additional protection do not need.
Installation of the depth GRUNDFOS (GRANDFOS) pump is performed as follows:
- The installation of the check valve on the pump nozzle is made. Water will not merge after power off.
The suction pipe is mounted with a coarse cleaning filter of a cupid form. It will save the working pumping chamber from heels. - After installing the check valve, the discharge nozzle is installed by which the water will be supplied up.
- The power cord in waterproofing is passed through the injection hose, it is fixed using a clip.
- The brackets provided on the top of the stainless housing are carried out polymer twine, which will be in the future to hold the pump in the well.
- Finished for launching the device is lowered into the mine's mine. Only twine is supported, the bunch of the cable with the hose does not carry any load.
- The rope is fixed on the bracket, which is located on the outside of the casing.
Please note that choose the correct installation algorithm to you will help you who deals with this professionally. If you want to install your own hands, consult the wizard to prevent errors.
Substitution and repair of the deep pump
Even the most reliable system is worn and can fail in work. To ensure the further operation of the device, it must be dismantled and replaced or repair. This procedure is done like this:
- Disconnect the power supply system and water supply from the pump unit.
- Remove the pump from the well. To do this, you need to use the help of comrades, since this procedure implies not small physical work.
- Disconnect the check valve and coarse filter, located at the entrance to the pump.
- Diagnose the product.
- Replace or repair failed parts.
- Carefully inspect all the nozzles, hoses and cable for damage.
- Clean the filter or replace it.
- Collect a pumping device and install it on the workplace.
When replacing the device, you should use new polymer ties and filters.
As you can see, installing and disassembling the deep pump unit can be performed independently. The main thing is to choose the device correctly and select the power of the pump under the appropriate well depth.

The drilling of the well on the site near the country house is completed. The next question that gets up to the owner is the choice of a pump that would be able to make the most effectively reach and transmit water to users. The optimal solution is to purchase a submersible pump for a well. This article will help you decide on the model and the main characteristics of the device.
How to choose a pump for a well
Water immersion pumps for wells are chosen based on:
- types of devices differing in principle of action;
- well parameters;
- technical characteristics of equipment.
Types of submersible pumps
How to choose a device that is most suitable for a well on the country site? First of all, it is necessary to decide on the type of pump.
All submersible pumps on the principle of action can be divided into several types:
- centrifugal;
- vortex;
- vibration;
- screw.
The submersible centrifugal pump for the well works through the creation of a turbulent flux by rotating diffusers.
Centrifugal pumps are easy to use and do not require special maintenance. The cost of equipment is relatively small. However, the device has both negative parties to which can be attributed:
- the need to install an additional filter at the bottom of the well. Centrifugal type pumps are very sensitive to entering the device of various impurities and / or small particles;
- entering the device is required, pre-filling the pump with water. The operation of the pump "In the dry" will lead to equipment breakdown.
One of the varieties of centrifugal devices are capable of pumping both clean and slightly clogged water.
Centrifugal submersible pumps can also be used for deep and small wells.
The immersion borehole type of vortex type lifts water due to mixing air supplied to the chamber through a special nozzle and working fluid.
Vortex pumps are distinguished by small power, so used only for shallow wells.
The principle of the action of the vibration pump is based on the movement of the rod due to the electric current.
The advantages of the vibration pump are:
- reduced requirements for water quality. The device can pump water with minor impurities without prejudice to wear;
- high reliability achieved by simplicity design.
Along with the essential advantages of equipment, there are disadvantages of the device to which include:
- vibration, created by the pump negatively reflected on the walls of the well. If the walls are not fixed by specialized materials, they gradually collapse;
- small working depth.
Vibrating pumps cannot be set below 5 m from the surface level of the Earth.
The submersible well pump pump consists of a housing (stator), inside which the spiral rotor rotates. When rotating the rotor, water is understood from the well and is fed into the pipeline.
Screw pumps are capable of lifting water from a depth of 40 - 50 m, but due to the increased friction created inside the design, the equipment requires periodic cleaning and replacing working parts.
Screw pumps are predominantly used in production purposes.
The well parameters affecting the selection of the pump
The selection of the immersion pump should be based on the well parameters, which can be obtained from the technical passport of the structure, decorated after manufacture or measure yourself with the help of cargo and a long rope. The main parameters that have a value when choosing a pump belong:
- depth, determined as the distance from the surface of the Earth to the bottom of the well. This indicator is necessary to determine the device's head;
- the diameter of the well is necessary to determine the diameter of the equipment. The pump should not touch the walls of the well, but also should not have too small diameter, as it affects the performance of the device;
The optimal diameter of the pump is 20-30 mm less than the hem diameter.
- debit well. The indicator determines the volume of water, which can be raised from the well per unit of time. The correct definition of the debit affects the choice of pump power. Exceeding of power over the debit can lead to "drying" of the water source;
- statistical and dynamic water levels. The statistical level determines the constant amount of fluid in the well. The dynamic level is calculated based on their constant consumption. These indicators are important to consider when choosing a pump to determine the dive level.
Determination of technical parameters
The technical characteristics of the pump, which should be paid to when choosing a submersible pump, are to be in the following parameters:
- equipment performance. This parameter shows how the volume of the fluid can pump the pump for a certain unit of time. Performance can be calculated in m³ / hour. The performance calculation is determined on the basis of consumption standards and installed in the house of sanitary devices on the basis of experts developed by experts;
- the height of the pressure on which the pump can raise water. When calculating the indicator, it should take into account the depth of the well and the length of the pipeline, and 10 m of length increase the height of 1 m. To ensure an additional reserve, the resulting indicator is recommended to be increased by 5 - 12 m. For example, the depth of a well is 10 m. For drains, a long 20 m pipeline is used for drainage . The minimum pump pressure must be 10 + 20/10 + 10 \u003d 22 m.
A good submersible pump for a well must meet all the necessary requirements.
Without defining the main parameters, it will not be possible to choose a submersible pump.
Additional parameters for pump selection
To determine which is better than the pump, it is also recommended to rely on the additional parameters to which you can attribute:
- water quality. If water contains a large number of impurities, it is more expedient to acquire a device equipped with additional filters or shredders;
- ways to start the equipment. If the well is located near the house, the pump can be turned on with hands. If the well is located in a significant distance from the buildings, it is better to get a submersible pump for a well with automation, that is, the device will work depending on the water consumption;
- cost of equipment. It is not recommended to purchase cheap devices, since in the case of submersible pumps there is a famous saying "Ichpets twice."
Montage Rules Submersible Pump
Installing the submersible pump in the well does not cause problems even in an inexperienced user. Each device is attached to a detailed instruction on the installation and use of equipment.
Installation of equipment occurs according to the following scheme:
- at the first stage, you must purchase all components: the pump, which will rise water, the cable for fastening, an additional electrical cable, check valve, if it is not included in the pump package;
- before installing, it is necessary to assemble the design into a single whole. Works begin with the installation of the check valve that prevents the reverse course of the liquid;
When installing the check valve, you need to pay attention to the course of water. It is usually shown by the arrow on the equipment itself.
- next is installed adapter for the pipe. All connections must be sealing with a fum-tape;
- at the next stage, a pipe is connected, intended for lifting the water of their well;
- after every 80 - 100 cm, the feed cable is fixed to the pipe. This can be done with the help of insulating tape or specialized clamps;
The cable cannot be attached to the stretch tube. It should be slightly weakened.
- it is attached with a steel cable that supports the pump in the well;
- the pump is lowered in a well to a previously defined level;
- power supply connected;
- on the upper part of the well is installed a headband preventing its pollution.
In more detail with the process of installing a well pump, you can get acquainted, looking at the video.
The selection and installation of the well pump should be taken with extreme attention. The wrong choice of equipment, as well as incorrect installation, will lead to the inoperability of the entire water supply system.
