The operating principle of the whirlwind pump SN 90V. Model range of well pumps "Vikhr"

Reading time: 7 minutes.

Well pumps used to provide water resources to residential and production premises. They operate at great depths with complete immersion in water over 50 meters. A powerful power plant allows water to be supplied uninterruptedly from wells and deep wells. Domestic example with high quality are well pumps Vortex.

Operating principle and types of Whirlwind pumps

The difference between Vortex submersible pumps is the principle of pumping water into the device. On this basis the following are distinguished:

• centrifugal;
• screw;
• vortex devices.

Centrifugal deep well pump lifts drinking water from a depth of up to 50 meters. At the same time, it copes with sand concentrations of up to 180 grams per cubic meter. The device is quite powerful and provides an uninterrupted supply of water. Such pumps include the Whirlwind SN-50N.

Its structure resembles a snail. It consists of a cylindrical body and an electric drive. A propeller with wide curved blades is connected to the drive. When submerged, the pump freely passes water inside the housing and it fills the entire space between the blades.

After this, the electric drive is activated, which intensively spins the screw. The water is pushed out by the propeller from the spaces between the blades to the inner surface of the housing walls. There is a hole here that connects the housing and the pipeline. The result is a pressure difference that causes the water to rise.

Devices of this type are equipped with special thermostats, which, in case of overload of the electric drive, turn it off.

Screw pumps maintain water pressure when immersed in a well or well with a depth of up to 100 m. At the same time, the immersion depth of the device from the surface of the water should not exceed 35 m. The design of the device allows you to work with water, the concentration of sand in which does not exceed 250 grams per cubic meter.

For a well, it consists of a thin cylindrical body connected to an electric power unit. Inside the case there is a screw mechanism consisting of a steel rotor (screw) and a rubber strator (internal rubber gasket housings with ribs). As a result of immersion to depth, water is supplied to the chamber of the screw mechanism.

Under the action of an electric drive, the internal screw turns inside the strator. By contacting together, the friction pair forms sealed spaces that are maintained until water is released into the pipeline. The next portion of water increases the pressure and throws the water mass even higher.

This operating principle is used on the Whirlwind SN-90V and Whirlwind SN-100V devices.

Only suitable for ponds with low sand content. Its maximum concentration should not exceed 40 grams per cubic meter. This device consists of a round flat body with two pipes and a disk inside. The work is provided by an electric motor.

When diving, water enters the chamber with the disk through the inlet pipe. Driven by an electric motor, a disk with blades creates a vortex flow of water along the walls of the housing. After this, it is pushed out into the outlet pipe by centrifugal force.

This class includes the Whirlwind CH 100 and the more productive model Whirlwind CH-50.

Model range of downhole devices of the “Vikhr” type

Based on their performance characteristics and scope of application, the following “Vikhr” borehole pumps stand out:

• sn-50N;
• SN-60V;
• SN-90V;
• SN-100V.

The device “Vikhr SN-50 N” is designed for pumping out water resources from wells and pits, the depth of which does not exceed 50 meters. In this case, drilling holes in the reservoir must be at least 10 cm. The device is suitable for working with water without impurities. In moderately and heavily polluted reservoirs, they quickly become unusable. The device is made of chrome steel. Equipped with a thermostat with a forced shutdown system.

The model has the following technical characteristics:

• water enters through the lower holes;
• rated power reaches 600 W;
• the pressure is maintained up to a height of 50 m;
• works with liquids up to + 35 degrees;
• device productivity 60 l/min.

When using a borehole pump sn 60v, you can lift water from reservoirs and wells with a depth of up to 60 meters and a diameter of up to 100 mm. The system uses water supply. Made from of stainless steel. Suitable for water containing abrasive materials not exceeding 40 grams per cubic meter.

The technical characteristics of the device are as follows:

• operating power is 370 W;
• optimal working depth 50-60 m;
• the water temperature should not exceed 35 degrees;
• the volume of pumped water is 25 l/min.

The immersion depth of the Vikhr sn 90v well pump is significantly higher than previous models and is 90 m. For easier immersion into the well and removal, the chrome-plated steel body is equipped with special hooks to which a cable or rope is attached. Optimal distance from the surface of the water mass to the device – 35 m. With deeper placement, negative pressure is applied to the mechanism components.

Performance qualities of the well pump Vikhr sn 90b:

• water passes through the upper channels;
• power consumption within 550 W;
• optimal pumping depth is 90 m;
• the device operates with liquid temperatures up to 35 degrees;
• productivity – 25 l/min.

Using the Vikhr sn 100v pump, you can pump out water masses from mines, deep pits and wells. In this case, the cross-section of the hole must be at least 120 mm in diameter. Like the previous deep model, CH 100B is equipped with additional hook rings that allow you to use the device more safely when diving. The case is made of stainless and partially chromed steel. Equipped with a thermal relay with the ability to turn off if the load is too high.

Characteristics:

• The upper inlet channel is used for water injection;
• operating power limit – 1100 W;
• the pressure is maintained up to a height of 100 m;
• permissible water temperature – + 35 degrees;
• volume of pumped out liquid – 40 l/min.

Not long ago, a model also appeared on sale that provides the deepest (in the model range) water withdrawal from a depth of 135 meters. Pump Whirlwind SN-135, like previous models, it is made of chrome and stainless steel. Its productivity is 40 l/min, and the power of the device is 800 W. For other points, the description repeats the previous model.

How to choose the right pump?

The first thing you need to pay attention to when purchasing is the diameter of the device. When entering the well, a cavity of at least 10% of the well diameter should remain between the channel wall and the surface of the apparatus. Therefore, for sources with a cross section of up to 10 cm, models CH-50N and CH-60V are used. If the hole diameter exceeds 10 cm, it is optimal to use CH-90N and CH-100V and CH-135.

When taking into account the power of the required device, it is better to focus on the depth of the well. Numerous reviews indicate that it is effective to take a model with a power slightly greater than the theoretically correct one. Since a high percentage of abrasive substances significantly reduces the capabilities of the device.

Some models have built-in special filters and cleaning systems that protect the device’s mechanisms from sand. This option is more expensive, but has a significantly longer service life. Also, when purchasing, you should definitely check the presence and working condition of the thermostat, which turns off the device when the engine reaches a temperature of 110 degrees.

How to install Vikhr well pumps correctly?

Proper installation of the pump will preserve its performance and functionality longer. To do this you need to adhere to certain rules. First of all, the device should run idle as little as possible. Such loads may damage the device.

When deepening the apparatus into a body of water, the distance to the surface of the reservoir must be at least 4 meters. The distance from the device to the bottom is at least 60 cm. When installing the mechanism, you should not rely only on the water supply channel. Fix the ends of metal cables with a small cross-section to the device body, and secure the free ends at the well outlet.

Periodically, you should remove the pump from the well and clean it of accumulated abrasive.

Whirlwind pump repair (video)

To provide residential and industrial premises with water far from the main water supply, well drilling is used. In this case, the supply of liquid from a deep source is carried out by borehole pumps. This type of pumping equipment is characterized by high pressure characteristics, continuous supply and a long service life.

Among domestic models of devices for wells, the Vortex borehole pump is popular. A wide range of models and modifications of the brand allow you to select a device ideally for the characteristics of the source.

1 Types of downhole devices Vortex and their features

Depending on the specific application, performance and other performance characteristics, there are several versions of Vikhr submersible pumps. The company produces models with upper water intake, designed for heavily polluted sources, and with lower water intake, which are used in wells with clean water. Based on the materials used, devices with components made of steel, brass, and durable polymers are distinguished. Mechanical seals in such devices are made of graphite or ceramics.

One of the main criteria for the distribution of wells pumping devices A vortex is a type of working body. In this regard, the following stand out:

• screw pumping apparatus;
• centrifugal submersible pump;
• vortex deep well pump.

1.1 Screw type devices

The screw electric pump is sufficient universal model. Such a device can be used not only in wells, but also in wells, mine tanks, and open reservoirs. Thanks to its design, the device is capable of passing liquid with a solid particle content of up to 250 g/cubic meter. m. Models of this type support pressure up to 100 m.

Design screw device assumes the presence of an electric motor installed in the upper part of the steel body, working chamber, electrical cable and eyelet with cable. The working chamber in screw devices consists of two elements:

• movable rotor (screw);
• fixed stator made of rubber.

The elastic stator has an internal thread. Inside it rotates, connected to the motor shaft, a rotor with external thread. The spiral threads of both elements are offset relative to each other. The result of this displacement is the appearance of sealed cavities in the stator during the movement of the screw. It is in these cavities that the device transports water from the suction holes to the outlet pipe. The total pressure created by the model depends on the number of cavities formed.

The main advantages of this type of pump are noiselessness, the ability to pump heavily contaminated water, and convenient repair or maintenance. In addition, the device can be used in both horizontal and vertical orientation, which expands its application possibilities.

1.2 Centrifugal well unit

As in the case of screw models, the centrifugal apparatus consists of a motor compartment and a working chamber, combined in one housing. Only the design of the working chamber of the device differs. It is a snail-shaped diffuser, inside of which a wheel with blades rotates on a shaft.

During operation, the wheel rotates, the blades capture water and rotate it in a circle. Under the influence of centrifugal force, the liquid is displaced under the walls of the diffuser. As a result of the displacement, an area of ​​​​discharged pressure is formed on the inlet pipe of the device, which leads to the suction of a new portion of water. In contrast, under the walls of the cochlea the pressure increases, which ensures high pressure. Selected options designs may include multi-stage impellers consisting of several standard discs with an impeller.

In terms of sensitivity to mechanical impurities, centrifugal models are less functional. The maximum content of abrasives in water should not exceed 160-180 g/cubic meter. m. The pressure characteristic of centrifugal devices is 50 m. They are distinguished by high productivity and wear resistance of components. To prevent the unit from overheating most of centrifugal models are equipped with an automatic emergency shutdown system.

1.3 Vortex deep unit

IN constructively Vortex-type models are similar to centrifugal ones. The difference is that the working disk of vortex devices is equipped with shorter blades of closed or open type. During operation, the blades take water from the inlet pipe and accelerate it in a circle under the influence of centrifugal force. During the circular motion, the flow again enters the blades, which gives it additional rotation and force. Vikhr brand devices use multi-stage pump options.

Thanks to the thinner design and small gaps between the impeller and the housing, the throughput of vortex-type units is only 40 g/cubic meter. m. Protection against larger particles is provided by a mesh filter installed on the suction openings. The feed height of the vortex apparatus is over 100 m, which allows it to be installed in a deep source.

Also, the advantages of models of this type include a small diameter, suitable for wells with a cross-section of up to 100 mm.

Among the shortcomings, the efficiency should be highlighted with an indicator of only 45%.

2 Main range of well models Vortex

For buyers Russian manufacturer offers a wide range of pumping devices for various parameters wells. Among the most popular models in the series are:

Model CH 50 is a vortex downhole tool with inlet holes located in the upper part of the body. The device is made of stainless steel, and the cross-section of the body allows the CH 50 to be mounted in a well with a minimum diameter of 100 mm. Liquid is taken from a depth of up to 50 m. The model operates on a motor with a power of 750 W. In a minute, such a unit is capable of pumping up to 40 liters of liquid.

The description of the CH 50 N model actually coincides with the previous model. The difference is that the centrifugal apparatus CH 50 N is equipped with a lower water intake. The technical characteristics of the device have the following values:

• the maximum productivity of the model is 3600 l/hour;
• liquid is lifted from a depth of up to 50 m;
• the minimum cross-section of the source is 100 mm;
• The maximum temperature of the pumped liquid is 35 degrees.

Using the Vikhr CH 60V borehole pump, water is drawn from wells with a minimum cross-section of 75 mm. The body of the centrifugal device is made of stainless steel, and Working wheel made of durable plastic. It is used both for supplying liquid to the home water supply and for watering the garden. Liquid suction occurs in the area where the housing is divided into the motor and working chambers (in the middle part). On the top cover of the housing there are eyes for a cable that secures the CH 60B to the head of the reservoir. The technical characteristics are as follows:

• the pressure characteristic of the device is 50 m;
• the content of abrasives in the liquid is no more than 40 g/cubic meter. m;
• volume of pumped liquid per hour – 3000 l;
• motor power – 800 W.

The Vortex CH 90V well pump is equipped with a thermal relay and a check valve, which prevents water from entering the device after it is turned off. The device is a screw model and is suitable for working with clean water. The minimum diameter of the well into which the device is mounted is 100 mm.

Main performance characteristics of the well pump Vikhr SN 90b:

• the liquid lifting height is 90 m;
• apparatus productivity – 1500 l/hour;
• motor power has a maximum of 550 W;
• The pipe adapter has a cross-section of 1 inch.

Water in the screw pump Vortex CH 100V is sucked through holes in the upper part of the housing. The screw working mechanism allows you to work exclusively with clean liquid. As in previous versions, the case is made of stainless steel. The cover of the device is equipped with eyelets for the cable. The powerful 1100 W motor has a protection class of ipx8. The operating characteristics of the model are as follows:

• the maximum performance of the unit is 2400 l/hour;
• the pressure characteristic has a value of 100 m;
• the device during operation is capable of immersing 60 m in the water column;
• The weight of the device is 13 kg.

The most productive model of the series is the Whirlwind SN 135. The device is a centrifugal type of pump. In addition to the well, the device can be installed in open reservoirs, tanks, and mine wells. Sensitive components of the device pump liquid containing abrasive particles up to 40 g/cubic meter. m. The body of the device is made of steel, and the material of the impeller is a dense polymer alloy.

The device has a motor with a power of 1800 W. This power unit is the most powerful in the line and provides performance up to 5700 l/h. In this case, the fluid temperature should not exceed 35 degrees, as the motor begins to overheat. In this model, the liquid supply height is 135 m, and the pump itself goes 60 m deep into the liquid thickness. Water is drawn in through suction holes in the central part of the housing. The minimum well section for the device is 102 mm.

Pumping products bearing the Vikhr brand have been known in Russia since 1974. At that time, the Kuibyshev Electromechanical Plant produced the first downhole submersible electric pumps. In 2000, production was moved to China, where, together with Russian specialists, production of various pumping equipment. Screw borehole electric pumps, also called worm or auger pumps, are used for pumping clean water from deep wells. One of these devices:

Submersible pump Vortex CH 90V

a well pump that has a maximum immersion in the well of 32 m. The distance from the bottom of the well to the edge of the housing must be at least 60 cm, from the surface to the device half a meter.

Downhole products are produced - a device with an upper intake pumps cleaner water, but there must be enough liquid for long-term operation. Maximum water supply 55 meters, more detailed schedule can be found in the product data sheet.

The body of the Vortex sn 90v deep-well pump is made of stainless steel. The length of the electric cable is 20 m, it is possible to extend it to the required length.

During operation, it is necessary to remember that operating the device “dry” is not allowed, and the temperature of the pumped water should be from one to 32 degrees.

The model is equipped by the manufacturer with a rubber check valve, which prevents water from pouring back into the container when stopped. But when operating the product in deep wells, a rubber valve will not work; it is best to immediately install it from metal. The standard outlet threaded hole of the check valve is 1 inch; if necessary, you can install an adapter fitting for a hose with a diameter of at least 3/4’’.

During operation, it must be remembered that the smaller the diameter of the supply hose, the greater the pressure. It is prohibited to artificially narrow the diameter of the installed hose.

There are special eye bolts installed on the sides of the body for fastening steel cable. Using a cable, the casing is immersed or then removed from the well.

It must be remembered that to avoid damage to the electrical connection between the electrical cable and the terminal box, you should not pull the cable, or even pick it up while the power supply is connected.

To prevent water hammer when air enters the chambers at the beginning of work, it is recommended to install a special device called a hydraulic accumulator.

It must be remembered that according to the safety requirements, during operation it is necessary to connect the product to a network where there is an electrical fuse with a cut-off current of no more than 16A, and which is triggered when the current rises to more than 30 mA/sec.

Does not require special maintenance during operation. But, if the product is left without use for more than 10 days, you need to take it out, drain the water and dry it.

The vortex data and characteristics can be seen in the picture.

Device

SN series designs

The series consists of a number of models with different principles actions: screw or centrifugal submersible electric pumps.

The fundamental difference between vortex and screw products is that the working body of a vortex pump is made of a wheel with blades. This wheel is placed in a chamber with an eccentric displacement of the outer walls; when the blades rotate, they capture water in the widest part of the chamber and move it to the narrower part, which creates pressure. For which type of pumps, a very important parameter is the rotation speed and engine power: the rotation speed creates pressure, and the power creates the amount of liquid ejected. Standard engine speed is 2800 rpm.

The screw deep-well pump vortex sn 90v differs from the vortex working body, which resembles an auger in a meat grinder. Capturing part of the liquid at the bottom, the auger pushes it upward, reaching the top the liquid is pushed out through check valve into the supply hose with sufficient pressure to lift water up to 40 m.

Attention! Need to remember. Due to its design, the creation of pressure largely depends on the tightness of the screw-bushing pair. Therefore, operation of such a product is allowed only with clean water, so that abrasives of sand or solid particles do not damage the surface of the sleeve mirrors.

The design with a centrifugal rotor allows pumping microparticles up to 15 microns. ( muddy water). But the auger can pump viscous liquids, but the blade cannot.

Design of the well pump Vikhr SN 90V

The principle of operation of a deep-screw pump is to push water between the cavities formed by a rotating screw and a bushing. The sleeve is made of plastic material (corded rubber metal); a rotating screw from the electric motor drive pushes water along the rubber walls of the housing, creating pressure at the outlet

Do-it-yourself repair of the Whirlwind CH 90V pump

It happens that during operation the product loses its former productivity, that is, it does not produce a certain amount of water per hour. One possible reason:

• Contamination of water inlet holes;
• bushing wear;
• screw wear.

If the contamination can be cleaned during disassembly, but wear or malfunction of the screw or bushing can only be done by replacing it. The cable may also be damaged as it exits the protective sealing tube. In this case, repairs should only be carried out by a specialist electrician.

Disassembly:

To disassemble the case, you need to use keys with a 10 edge to unscrew the four screws on the pins and the eyes. Remove the cover carefully so as not to damage the gasket between the body and the cover. After the cover is removed, the shaft, bushing, and check valve become accessible for inspection.

Carefully remove the check valve from the top cover, without using sharp objects (only with your hands) - the rubber must be elastic, the movable valve cover and the body must not be damaged. If there are no visible breakdowns, then after cleaning the coked parts or grille inlets, the product will work as before.

Device

The device consists of a pressure flange, a working part housing, a stator housing, and an electric motor housing.

The auger and body are made of stainless steel, the auger bushing is rubber-metal. The asynchronous type motor is placed in oil bath, protection class IP68.

So, your assistant began to dispense less water. Most likely the malfunction is in the working parts that come into direct contact with water - this is the inside of the housing, the auger and its bushing. It is strictly forbidden to launch deep products without water, so all checks should be carried out exclusively immersed in liquid.

How to disassemble a vortex CH 90V

We remove the cover under which the check valve is located, pull out the auger bushing, after which the auger itself is unscrewed. The auger is screwed into the drive shaft on the “left” thread. If the thread is acidified, there are turnkey edges under the protective sleeve.

Checking the motor

Checking the integrity of the windings includes checking for breaks and measuring the insulation.
To check the continuity of the circuit, two tests are carried out:

• integrity of the phase wire circuit and motor windings;
• insulation resistance measurement.

To do this, you need to use a multimeter and understand the operating principle and design of the vortex pump CH 90V. To measure the first parameter, let's put the multimeter in ohmic resistance mode. Then, touching the plug pins with the probes, we will take a measurement; the reading should be no more than 1 ohm. The ground wire is measured by touching the ground contact of the plug and the housing. If the resistance is more than 1 Ohm, then there may be a break in the ground or phase wire in the motor winding itself, the cable plug or wire.

The next check is to determine the amount of insulation of phase wires from breakdown to the housing. To do this, connect the measuring probe of a multimeter to the pins of the electrical wire plug in the 200 MOhm mode. the second probe on the body (the place of contact must be clean), the resistance during measurement must be at least 200 MOhm.

Afterwards, the operation of the engine is checked; to do this, it is enough to connect the power plug of the electric motor to the electrical network and pay attention to the noise of the bearings during operation and the stability of the speed. The noise from the bearings should be smooth without clicks or crunching, the speed should be stable. speed of household devices = 2800 rpm.

Inspection of working parts

Next, the auger and bushing are inspected; they should not have significant damage and be in close contact with each other; to do this, simply insert the bushing into the auger; they should fit into each other with friction.
After cleaning the parts, assembly is carried out in the reverse order. If you are still not sure how to properly disassemble the vortex pump CH 90V, then it is best to contact a specialized center, where specialists will carry out professional diagnostics.

Washing parts

During long-term use, depending on chemical composition water, less and more often the body and parts are subject to mineral deposits, and simple steel rusts.

Oxides and hydroxide (rust) are most effectively removed by the manual method - brushing the metal and washing with water. Ideally rinsing under jet high pressure(mini washer). The deposit of carbonate salts, which turn into carbonate minerals during deposition: organite, coccide, can be easily removed using dilute hydrochloric acid and a metal sponge, of course, followed by thorough washing.

rubber, plastic parts can be washed in a strong solution of table salt. But if you decide to disassemble it down to the parts, it is best to supply new spare parts, especially valves and gaskets.

So, if the assistant has stopped dispensing water to the pump and has lost productivity, and you decide to repair the whirlwind sn 90v pump, then most likely it has become dirty, most often due to calcium deposits (popularly limestone). If the deposit is not yet large and has not become coked, then you can do without chemicals and can be used for cleaning citric acid. It removes organic salt deposits well.

Borehole pump Vikhr CH 90V - reviews:

Korshunov Sergey 2013 Kostroma

What's good: stainless steel body, good performance.
What's bad: the studs hold the 2 halves of the body together. In a year, a year and a half, there is a possibility that the casing will crumble right in the well. It's amazing who came up with this - the body is made of stainless steel, the tightening pins are steel. I assume that initially the studs were also made of stainless steel, but in order to save money, China offered its own assembly option. Another disadvantage is that it is used only for clean water. Be sure to choose a screw made of solid stainless steel, the chrome plated peels off and then jams due to increased friction with the bushing. The approximate service life is 2-3 years. But it looks like it's worth the money.

Anonymous 2016

I consider it a positive property: oil in the motor - this gives additional electrical properties to the windings. There are eye bolts for suspension, decent pressure. The store stated that the cable length was 20 meters, but I didn’t check it; at home it turned out to be a little longer. It pumps from a depth of 20 m. The pressure is good, about the same as fully opening a tap in an apartment. I'm tired of constantly turning the socket on and off, I'm thinking of purchasing automatic system starting the engine from the pressure in the water line. It's been working for six months, no problems so far.

Sergey 2017

I consider the advantages to be the low price, high-quality assembly of the whirlwind pump sn 90v, the review is good, although the productivity is low, but I have a non-standard well - 100 m deep. I asked the sellers for advice, they said that this type is for deep well doesn't work. I use it to set containers. Suspension with 6 mm cable. The length of the cable upon purchase was 20 m, the consultant said that it could be increased. I cut the cable near the plug, extended it, nothing, it works fine for a year and a half, no complaints. The cable is three-core in rubber, inside there are silk threads and braiding.

You can buy Whirlwind CH 90V at specialized dealerships or on Internet resources. To avoid buying counterfeits, it is best to contact trusted large centers where they value their reputation and you can consult with sellers online or by correspondence.

The domestic manufacturer of various pumping equipment under the Vikhr brand today offers a fairly extensive model line of its products. But in this article we will be interested in the “Vikhr” borehole pumps. The thing is that units of this type have become very popular today, because with their help you can organize water supply country houses not only from wells, but also from wells. And everyone knows that the water in wells is cleaner and its flow rate is quite high. That is why wells are summer cottages today they began to appear more and more often regarding wells. And even the complexity of their construction does not repel the owners of country houses.

Talk about submersible pumps The borehole-type “vortex” is needed as a very high-quality device. Their models have excellent power and good pressure, and since these characteristics are most often the main selection criteria, they are also the main popularity of the units.

Well pump "Vikhr"

Types of Vikhr pumps for wells

Let's start with the fact that the manufacturer today offers several purely constructive positions. That is, all proposed models are divided into three groups:

• centrifugal pumps;
• vortex;
• screw

Attention! Let’s immediately make a reservation that centrifugal devices are equipped with a lower water intake, vortex and screw devices are equipped with an upper one. Basically, according to this design feature they can already be distinguished.

Centrifugal model

Now distinctive features designs. The Vikhr centrifugal pump differs from a vortex pump only in its impeller with blades. In a centrifugal one, they are curved, which is why, when water hits them, it immediately rebounds to the periphery, where an area of ​​​​high pressure is formed. And in the center of the wheel an area will form low pressure. And since centrifugal force acts on the water inside the compartment, that is why the name of these models appeared.

The impeller of vortex devices has smooth blades, running from the center to the edge without bending. This design allows you to create water vortices between them, which in turn create pressure inside the working chamber. However, it should be noted that pumps of this type have a small SOP compared to centrifugal ones, so they are inferior to the latter in both pressure and performance.

As for screw units, this is a unique design in which there are two screw parts: a screw and a chamber. They repeat each other in configuration internal cavity, which is the screw. There is a small gap between them, through which the pumped liquid moves. It should be noted that “Vikhr” screw well pumps are not as popular as the two previous models. They are more expensive, however, they have good efficiency and fairly high technical characteristics. For example, at centrifugal pumps the maximum pressure is 50 m, for screw ones 100 m when the device is immersed to a depth of 35 and.

Screw unit with top water intake

All three models can also be compared in terms of pumping water from to varying degrees pollution. Many may think that this is not the most important indicator, and make a big mistake. After all, as often happens when you come to a store to buy. He selects a well pump based on performance and pressure. And this is correct, but we should not forget about the concentration of suspended particles in water.

• the Vikhr centrifugal pump can pump water with an impurity concentration of up to 180 g/m³;
• vortex up to 40 g/m³;
• screw up to 250 g/m³.

That is, it turns out that vortex models are the least capricious in terms of pumping contaminated water. Therefore, they can be used not only for installation in wells, but also in mine wells.

Popular models

It should be noted that there are a small number of popular models that are used today by residents of suburban villages. Let's look at two of them. By the way, it should immediately be noted that units of this type are designated “CH”, that is, a well pump.

Whirlwind CH 90v

So, the “Vikhr” CH 90v well pump is a screw-type unit with an upper water intake. Let's start with him technical characteristics.

• The pump diameter is 90 mm, which allows them to be installed in wells with a barrel diameter of 100 mm. And they, as you know, are considered the most common.
• It can be submerged to a depth of 35 m.
• Its productivity is 25 l/min.
• Head – 90 m.
• Electric motor power – 0.55 kW.
• The package includes electrical cable 17 m long.
• Powered by network alternating current voltage 220 volts.
• Can pump water with temperatures up to +35C.
• The recommended distance to the bottom of the well is 60 cm.

CH 90v

The body of the device is made of stainless steel, internal parts are made of brass and chrome-plated steel. But according to consumer reviews, it turns out that the CH 90v pump also has some disadvantages. For example, the studs and lugs are made of plain steel, so they rust quickly. And with long-term use they simply break down. As consumers say, after three years of operation, the pump may end up at the bottom of the well forever. The eye will rust to the end, and when lifted, the pump will simply break off and fall down. It will be almost impossible to get him out of there. Moreover, the depth of its descent is 35 m.

Speaking about the “Vikhr” CH 90v borehole pump (its design and technical characteristics), it should be noted that this pumping unit has exactly the design that can be used for pumping not very clean water. That's probably why this model so popular today among residents of suburban villages. After all, a depth of 35 m is an opportunity to build a well on sand, in which suspended impurities great amount, especially at the first stage of operation. This is exactly what a screw type pump can handle.

Vortex CH 50

The next popular model is the “Vikhr” CH 50 well pump. This is a centrifugal type unit with a lower water intake. Here are its technical characteristics.

• Capacity – 60 l/min.
• Head – 50 m.
• The power of the electric motor varies depending on the modification: either 600 or 750 W. The first is installed in the CH-50N model, the second in the CH-50.
• The diameter of the device is 100 mm.
• Can dive to a depth of 40 m.
• Can pump water with temperatures up to +35C.

The pump body is made of stainless steel, the pump part is either plastic or brass. This again depends on the manufacturer. By the way, about the manufacturers. Borehole, submersible and surface pumps "Vikhr" are produced in Russia, China, and Latvia.

There are also more compact devices in the Vikhr model line of well pumps. For example, grade CH 60. Its diameter is only 75 mm, which allows the device to be installed in wells with a barrel diameter of 80 mm. That is, when deciding on the choice of unit, it is necessary to take into account the possibility of installing it in the shaft of a hydraulic structure. And if a well with a diameter of 80 mm was drilled on the site, then the optimal pump for it is CH-60. The two previous positions clearly simply will not fit into such a well.

Like the CH-50, the CH-60 has two modifications that differ from each other in electric motor power and performance. CH-60 – 800 W, CH-60v – 370 W. Respectively 50 and 25 l/min.

Key advantages of Vikhr well pumps

So, let's summarize all of the above and note the advantages of this type of equipment.

• The first thing I would like to draw attention to is the small dimensions device in which it can pump water to a fairly decent height. And although the performance of the unit is not the highest, it is enough to provide water for a small Vacation home with several consumers.
• The high reliability of the pump is confirmed by its degree of protection, which categorizes it as IPX8. Each manufacturer sets this category himself. But there are two positions in it that are considered standard. This is an immersion depth of at least 1 m, in which the pump must operate for at least half an hour.
• Various caliber electric motors used in different models, guarantee a fairly decent pressure. In any case, the minimum of them is 40 m; this is the optimal indicator for domestic borehole pumps.
• All Vikhr well pumps are designed for frequent switching on and off, which is an important indicator for units of this type. Especially if the pumps do not operate as part of pumping station or without storage tank.
• For such technical characteristics, the pumping unit does not have the most high price. And this is one of the biggest advantages.

Attention! The cable length of 17 m is not always enough to ensure the installation depth of the device. Therefore, it can be increased. The only requirement for twisting is that it must comply with electrical safety requirements. The ideal solution is if the twist is located outside the wellbore.

Variety of models

Installation rules

Like all well pumps, the “Vikhr” is installed in the shaft of a hydraulic structure, suspended on a cable. To do this, you can use nylon or metal (stainless steel) cables. The unit has specially installed eye bolts, and the cable is attached to them.

You can connect a hose to the supply pipe with clamps, and a pipe to the threaded adapter. An electrical cable is also attached to them. For them, holes are provided in the well head, for each separately. The cable is attached to the head with special eyes.

It is very important to correctly lower the unit into the shaft of the structure. In this case, all elements: cable, hose and cable are discharged down simultaneously and evenly. This process can usually be handled by one person. The small dimensions of the device allow this to be done.

Conclusion on the topic

To summarize all of the above, we must pay tribute to the “Vikhr” (well) pump. The variety of models makes it possible to select a unit of a type that would fully satisfy its operating conditions. But when choosing, you will have to take into account the contamination of the pumped water. Therefore, before giving credit to one or another model, it is necessary to analyze the water from the well.

Advantages: the pump pumps perfectly for 2 years

Disadvantages: the studs that attach the pump to the motor are made of ferrous metal, after six months the water ate them up... they need to be made of stainless steel!! The fastenings to the rope were also eaten away by the water.. everything must be made of STAINLESS STEEL.... THE SICK POINT IS THE STUD

Comment: overall the pump is excellent NO PROBLEMS

Advantages: Value for money

Disadvantages: The studs that secure the pump rust. Sensitive to network voltage. If it is less than 190-200 volts, it does not turn on at all.

Comment: I bought it at a market in the Moscow region in May 2015 for 7,000 rubles. In May, he lowered it into a well (18 meters). Used until October simple mode- plugged the plug into the socket - pumped up the containers - removed the plug from the socket. No problem. I decided not to take it out for the winter and hung in the water all winter. In May 2016, I took it out for an external inspection. The mounting pins are completely rusty. The stainless steel body is ok. We mounted it in an automatic system with a hydraulic accumulator and a pressure switch. I worked well for the season, without any problems. The only remark is that when there were cold evenings and the heating was turned on at the dachas, it did not work due to a decrease in the voltage in the network. But then at some point when the voltage increased it worked again. We need to install a voltage stabilizer, but we haven’t gotten around to it yet. In general, for 5200, for which you can now buy it, it is a good option for a summer residence. Enough for two seasons. (maybe more, but you probably need to lift it, disassemble it, maintain it, change the studs, I’m reluctant) I’m thinking of buying a couple, as consumables, change once every two years, normal. :-) There was a very, very little in the well fine sand- did not affect the work in any way.

Advantages: PRICE! This is the best offer on the Internet. Good performance

Comment: I don’t know why I don’t pay so much good reviews, but we’ll give the same one to our parents for the dacha, the performance is enough for the eyes + they are now even cheaper than 3 years ago. PEOPLE - a life hack especially for you: in order not to force the pump and extend its service life, install a check valve and immediately change the studs to stainless steel and you will be happy.

Advantages: From experience of use, I want to confirm that this pump is ideal for organizing a water supply system for a private home. Has been working for 4 years.

Disadvantages: only advantages for the money.

Comment: the sand in the well gives me no peace that soon I will have to buy a new one. but I’ve already worked for 4 years and I’m happy.

After five months of use, the studs rotted, so if you buy them, immediately replace them with stainless steel. This is a good pump. It will work in the country.
