Borehole pump whirlwind sn 90v design. The principle of operation and types of borehole pumps whirlwind

The domestic manufacturer of various pumping equipment under the brand name "Whirlwind" offers today a fairly extensive model line of its products. But in this article we will be interested in the Whirlwind 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 the wells is cleaner and its flow rate is quite high. That is why the wells 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.

It is necessary to talk about submersible pumps "Whirlwind" of the borehole type as about very high-quality devices. 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.

Pump for wells "Whirlwind"

Varieties of pumps "Whirlwind" for wells

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

  • centrifugal pumps;
  • vortex;
  • screw.

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

centrifugal model

Now distinctive features structures. The centrifugal pump "Whirlwind" differs from the vortex only in the impeller with blades. In centrifugal, they are curved, which is why, falling on them, water immediately bounces to the periphery, where a high pressure area is formed. And in the center of the wheel an area will be formed low pressure. And since centrifugal force acts on the water inside the compartment, that is why the name of these models appeared.

At the impeller of vortex devices, the blades are even, going from the center to the edge without bends. This design allows you to create water turbulences between them, which in turn create pressure inside the working chamber. True, it should be noted that pumps of this type have a small UPD compared to centrifugal ones, so they are inferior to the latter both in pressure and in productivity.

As for screw units, this is a unique design in which there are two screw parts: an auger and a chamber. They repeat each other in the configuration of the internal cavity, which is the screw itself. Between them there is a small gap, through which the pumped liquid moves. It should be noted that screw borehole pumps "Whirlwind" 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 head is 50 m, for screw 100 m when the device is immersed to a depth of up to 35 and.

Screw unit with top water intake

All three models can also be compared in terms of pumping water with varying degrees of contamination. Many may think that this is not the most important indicator, and make a big mistake. After all, as often happens when buying comes to the store. He selects a borehole pump for performance and pressure. And rightly so, but do not forget about the concentration of suspended particles in water.

  • centrifugal pump "Whirlwind" 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 most unpretentious in terms of pumping contaminated water. Therefore, they can be used not only for installation in wells, but also in shaft wells.

Popular Models

It should be noted that there are a small number of popular models that residents of suburban villages use today. Let's consider two of them. By the way, it should immediately be noted that units of this type are marked with the marking "SN", that is, a borehole pump.

Whirlwind CH 90v

So, the borehole pump "Whirlwind" CH 90v is a screw-type unit with an upper water intake. Let's start with its technical characteristics.

  • The pump diameter is 90 mm, which allows them to be installed in wells with a bore diameter of 100 mm. And they, as you know, are considered the most common.
  • It can be submerged to a depth of up to 35 m.
  • Its productivity is 25 l/min.
  • Head - 90 m.
  • Electric motor power - 0.55 kW.
  • The package includes an electric cable 17 m long.
  • Works from the network alternating current voltage of 220 volts.
  • Can pump water 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, the 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 drawbacks. For example, studs and eyelets are made of plain steel, so they rust quickly. And when used for a long time, they simply fail. As consumers say, after three years of operation, the pump may be at the bottom of the well forever. The lug 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 lowering is 35 m.

Speaking about the downhole pump "Vikhr" CH 90v (its device 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. Perhaps that is why this model is 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 there is a huge amount of suspended impurities, especially at the first stage of operation. It is with them that a screw-type pump can handle.

Whirlwind CH 50

The next popular model is the Whirlwind CH 50 borehole pump. This is a centrifugal type unit with a lower water intake. Here are its specifications.

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

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

There are in the model line of borehole pumps "Whirlwind" and more compact devices. For example, brand CH 60. Its diameter is only 75 mm, which allows you to install the device in wells with a bore diameter of 80 mm. That is, when deciding on the choice of the unit, it is necessary to take into account the possibility of its installation 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 do not fit in such a well.

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

Model CH-60

Key advantages of borehole pumps "Vikhr"

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 overall dimensions of the 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 a small amount of water. Vacation home with multiple users.
  • The high reliability of the pump, confirmed by its degree of protection, which classifies it as IPX8. Each manufacturer sets this category for himself. But there are two positions in it that are considered the standard. This is an immersion depth of at least 1 m, in which the pump must work for at least half an hour.
  • Various types of electric motors used in different models, guarantee a decent enough pressure. In any case, the minimum of them is 40 m, this is the optimal indicator for domestic borehole pumps.
  • All Whirlwind 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 work as part of pumping station or without storage tank.
  • For such technical characteristics, the pumping unit does not have the highest price. And this is one of the biggest pluses.

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 lineup

Installation rules

Like all borehole pumps, "Whirlwind" 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 bolts with eyes, and the cable is attached to them.

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

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 bled down simultaneously and evenly. Usually one person can handle this process. The small dimensions of the device make it possible.

Downhole pump installation

Conclusion on the topic

Summing up all of the above, we must pay tribute to the pump "Whirlwind" (borehole). A variety of models makes it possible to choose a unit of this type, which would fully satisfy the conditions of its operation. 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.

Pump products with 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, the production of various pumping equipment was launched. Screw downhole electric pumps, which are also called worm or screw pumps, are used to pump clean water from deep wells. One of these devices:


Submersible pump Whirlwind CH 90V

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

Downhole products are produced - top intake devices pump cleaner water, but there must be enough fluid for long-term operation. The maximum water supply is 55 meters, a more detailed schedule can be found in the product data sheet.

The housing of the deep pump whirlwind sn 90v 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 must be remembered that the operation of the device "dry" is not allowed, and the temperature of the pumped water should be from one to 32 degrees.

By the manufacturer, the model is equipped with a rubber check valve which does not allow water to be poured 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 a hose adapter for 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 forbidden to artificially narrow the diameter of the installed hose.

On the sides of the housing there are special eyebolts for attaching a steel cable. With the help of a cable, the body is immersed or then removed from the well.

It must be remembered that in order to avoid damage to the electrical connection between the electrical cable and the terminal box, do not pull on the cable, or even pick it up when the mains 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 requirements of Safety, during operation, it is necessary to connect the product to a network where there is an electric fuse with a cut-off current of not more than 16A, and which is triggered when the current rises more than 30 mA/sec.

During operation does not require special maintenance. But, if the product is out of use for more than 10 days, you need to get it, drain the water and dry it.

Data on the vortex and characteristics can be viewed in the picture.

Device

CH Series Structures

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

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

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

Attention! It must be remembered. Due to its design, the creation of pressure largely depends on the tightness of the screw-bushing pair. Therefore, this product may only be used with clean water so that abrasive sand or solid particles do not damage the surface of the hub mirrors.

The design with a centrifugal rotor allows pumping of microparticles up to 15 microns. (cloudy water). On the other hand, auger can pump viscous liquids, but a bladed one cannot.

Borehole pump device Whirlwind CH 90V

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

Do-it-yourself pump repair Whirlwind CH 90V

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

  • Pollution of the water inlet holes;
  • bushing wear;
  • screw wear.

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

Disassembly:

To disassemble the case, it is necessary to unscrew the four screws on the studs and the eyes with keys with a face of 10. 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, check valve becomes available for inspection.

From the top cover, carefully, without the use of sharp objects (only with your hands), the check valve is taken out - the rubber must be elastic, the movable valve cover and the body are not damaged. If there are no visible breakdowns, then after cleaning the coking parts or the grate inlets, the product will work as before.

Device

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

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

So, your assistant began to give out less water. Most likely a malfunction in the working bodies that come into direct contact with water is inner part body, auger and its bushing. It is strictly forbidden to launch deep products without water, therefore all checks should be carried out exclusively immersed in liquid.

How to disassemble the vortex CH 90V

We remove the cover, under which there is a check valve, 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.

Motor check

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

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

To do this, you need to use a multimeter, and understand the principle of operation and the device of the pump vortex sn 90v. To measure the first parameter, put the multimeter in the ohmic resistance mode. Then, touching the pins of the plug with the probes, we will measure, the reading should be no more than 1 ohm. The ground wire is measured by touching the ground contact of the plug and the case. If the resistance is more than 1 ohm, then a break in the ground or phase wire in the motor winding itself, cable plug or wire is possible.

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

After that, the operation of the engine is checked, for this it is enough to connect the power plug of the electric motor to the mains, while paying attention to the noise of the bearings during operation and the stability of the revolutions. The noise from the bearings should be smooth without clicks or crunch, the speed is stable. the frequency of revolutions for household appliances = 2800 rpm.

Inspection of working bodies

then the auger and sleeve are inspected; they should not have significant damage and should be in close contact with each other; for this, it is enough to insert the sleeve into the auger; they must enter into each other with friction.
After cleaning the parts, reassemble in reverse order. If you are still not sure how to properly disassemble the vortex pump sn 90v, then it is best to contact a specialized center where specialists will diagnose professionally.

Parts washing

At long-term operation depending on the chemical composition water, less and more often the case and parts are exposed to mineral deposits, and plain steel rusts.

Oxides and hydroxide (rust) are most effectively removed by the manual method - with a metal brush and washing with water. Ideally, washing under a high pressure jet (mini wash). The deposition of carbonate salts, which, when deposited, turns into carbonate minerals: organite, coccid, can be easily removed with dilute hydrochloric acid and a metal sponge, of course followed by thorough rinsing.

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

So, if the assistant stopped giving water to the mountain, having lost productivity, and you decided to repair the vortex pump sn 90v, then most likely it became contaminated, most often it is a calcium deposit (popularly limestone). If the plaque is not yet large and has not coked, then you can do without chemistry and you can apply for cleaning citric acid. It removes the plaque of organic salts well.

Borehole pump Whirlwind CH 90V - reviews:

Korshunov Sergey 2013 Kostroma

What's Good: Stainless steel body, good performance.
What is bad: the studs hold the 2 halves of the body together. In a year, a year and a half, there is a chance that the body will crumble right in the well. It's amazing who came up with this - a stainless steel case, steel studs tightening. I assume that initially the studs were made of stainless steel, but in order to save money, China offered its own assembly option. I also attribute to the disadvantages that it can only be used for clean water. Be sure to choose an auger made of solid stainless steel, chrome-plated will peel off and then wedge due to increased friction with the bushing. Approximate service life is 2-3 years. But it seems to be worth the money.

Anonymous 2016.

I attribute it to positive properties: oil in the motor - this gives additional electrical properties to the windings. There are eye bolts for suspension, decent pressure. The store declared a cable length of 20 meters, did not check, it turned out to be a little more at home. It pumps from a depth of 20 m. The pressure is good, approximately like a full opening of a tap in an apartment. Tired of constantly turning the socket on and off, I think to buy automatic system turning on the engine from the pressure in the water line. Works for six months, so far without remarks.

Sergey 2017

I attribute the low price to the merits, the high-quality assembly of the pump vortex sn 90v is good, though low productivity, but I have a non-standard well - 100 m deep. I turned to the sellers for advice, they said that this type is not suitable for a deep well. I use for a set of containers. Suspension on 6 mm cable. The cable length upon purchase was 20 m, the consultant said that it could be extended. I cut the cable near the plug, increased it, nothing, it has been working normally for a year and a half, there are no complaints. Three-core cable in rubber, silk threads and braid inside.

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

To provide residential and industrial premises well drilling is used for water away from the main water supply line. In this case, the supply of fluid from a deep source is carried out by borehole pumps. This type of pumping technology is characterized by a high pressure characteristic, continuity of supply and a long service life.

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

1 Types of downhole devices Whirlwind and their features

Depending on the specifics of the application, performance and other performance characteristics, there are several versions of the Whirlwind submersible pumps. The company produces models with an upper intake of water, designed for highly polluted sources, and with a lower one, which are used in wells with clean water. According to the materials used, devices with nodes made of steel, brass, and durable polymers stand out. Mechanical seals in such devices are made of graphite or ceramics.

One of the main criteria for the distribution of downhole pumping devices Whirlwind is the type of working body. In this regard, stand out:

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

1.1 Screw type devices

Screw electric pump is enough universal model. Such a device can be used not only in wells, but also in wells, mine tanks, open reservoirs. Due to its design, the device is capable of passing liquids with a solids content of up to 250 g / cu. m. Models of this type support pressure up to 100 m.

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

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

The elastic stator has internal thread. Inside it rotates, connected to the motor shaft, a rotor with an external thread. The helical 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. The total pressure created by the model depends on the number of cavities formed.

The main advantages of this type of pumps are noiselessness, the ability to pump heavily polluted water, convenient repair or maintenance. Besides the device can be used both in horizontal, and vertical orientation that expands possibilities of application.

1.2 Centrifugal downhole unit

As in the case of auger 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 which a wheel with blades rotates on a shaft.

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

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/cu. m. The pressure characteristic of centrifugal devices is 50 m. They are characterized by high performance and wear resistance of the nodes. To prevent overheating of the unit, most of the centrifugal models are equipped with an automatic emergency shutdown system.

1.3 Vortex deep unit

In constructive terms, vortex-type models are similar to centrifugal ones. The difference lies in the fact that the working disk of the vortex apparatus is equipped with shorter blades of a closed or open type. During operation, the blades take water from the inlet pipe and disperse it in a circle under the action of centrifugal force. During the circular motion, the flow again enters the blades, which betrays it with additional rotation and strength. Whirlwind brand devices use multi-stage pump options.

Thanks to the slimmer design and small gaps between impeller and housing, throughput aggregates of the vortex type is only 40 g / cu. m. Protection against larger particles provides a mesh filter installed on the suction holes. The feed height of the vortex apparatus is over 100 m, which allows it to be mounted 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, it is necessary to highlight the efficiency with an indicator of only 45%.

2 Main range of downhole models Whirlwind

The Russian manufacturer offers customers a wide range of pumping devices for various well parameters. Among the most popular models of the series are:


Model CH 50 is a vortex downhole tool with inlets located in the upper part of the body. The apparatus is made of stainless steel, and the section of the body allows mounting the CH 50 into a well with a minimum diameter of 100 mm. Liquid is taken from a depth of up to 50 m. The model is based on an engine with a power of 750 watts. 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 lies in the fact that the CH 50 H centrifugal apparatus is equipped with a lower water intake. Specifications devices have the following values:

  • the maximum productivity of the model is 3600 l / h;
  • the 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.

With the help of a borehole pump Whirlwind CH 60V, water is taken from wells with a minimum cross section of 75 mm. The body of the centrifugal device is made of stainless steel, and the impeller is made of durable plastic. It is used both for supplying liquid to domestic plumbing, and for watering a garden or vegetable garden. The liquid is sucked in in the area where the housing is divided into the motor and working chamber (in the middle part). On the top cover of the body there are eyelets for a cable, with which CH 60V is fixed in the head of the reservoir. Specifications are as follows:

  • the pressure characteristic of the device is 50 m;
  • the content of abrasives in the liquid is not more than 40 g / cu. m;
  • the volume of pumped liquid per hour - 3000 l;
  • motor power - 800 watts.

The complete set of the borehole pump Whirlwind CH 90V is supplemented with a thermal relay and a check valve that prevents water from entering the device back after it has been turned off. The device belongs to screw models and is suitable for working with clean water. The minimum diameter of the well in which the device is mounted is 100 mm.

The main performance characteristics of the borehole pump Whirlwind CH 90b:

  • liquid lifting height is 90 m;
  • device productivity - 1500 l / h;
  • motor power has a maximum of 550 W;
  • the adapter for the pipeline has a section of 1 inch.

Water in the screw pump Whirlwind CH 100V is sucked in through holes in the upper part of the casing. 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 a cable. The powerful motor with a power of 1100 W is distinguished by the IPX8 protection class. The performance characteristics of the model are as follows:

  • the maximum performance of the unit is 2400 l / h;
  • the pressure characteristic differs in the value of 100 m;
  • the device during operation is capable of diving 60 m into the water column;
  • the weight of the apparatus is 13 kg.

The most productive model of the series is Whirlwind CH 135. The device belongs to the centrifugal type of pumps. In addition to the well, the device can be mounted in open reservoirs, reservoirs, shaft wells. Sensitive components of the apparatus pump liquid containing abrasive particles up to 40 g/cu. m. The body of the apparatus is made of steel, and the material of the impeller is a dense polymer alloy.

The device is equipped with a motor with a power of 1800 watts. This power unit is the most powerful in the line and provides performance up to 5700 l / h. In this case, the temperature of the liquid 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 deep into the liquid column by 60 m. Water is taken in by suction holes in the central part of the housing. The minimum well section for the device is 102 mm.

Every day, owners of private houses or summer cottages are increasingly asking themselves the question of drilling a well or a well on their territory. But in addition to drilling, you also need to somehow supply the extracted water to the house, and here the owners go into a stupor, and a lot of questions arise in their heads. Which well pump to choose? What should be its performance? Choose an expensive model or save? Consider the domestic borehole pump Whirlwind sn-100, because they have proven themselves to be reliable and inexpensive products. Over the long period of the company's existence, the model range of pumps has become very large, since an individual tool is required for each working condition.

The main purpose of borehole pumps is to pump water from various sources, for example: a well, a deep well or a reservoir. Since the device operates under extreme conditions for it, it requires an increased degree of protection against corrosion, electric shock and abrasive materials.

Based on the above requirements, the Whirlwind borehole pumps have a protection class against short circuit and electric shock IPX8, which allows the use of these devices at depths from 1-2 to 70 m with different levels of contaminants.

The difference between models according to the principle of operation


V model range"Whirlwind" has three types:

  • Borehole pump Whirlwind CH 100, CH-50 is a product that works on the vortex principle. In such models, water is captured from above;
  • Pumps for wells SN-90V and SN-100V use screw water capture and carry out water intake from above;
  • The CH-50N model uses a centrifugal principle of operation and liquid intake in the lower part.

Vortex borehole pumps are designed for the intake and supply of the purest water with a content of abrasive particles (sand) of not more than 40 grams per cubic meter.

The device is quite simple, its working part is a flat disk with blades along the edges. This disc is placed in an annular cavity with tightly fitted ends. Along the edges of the cavity there are inlet and outlet pipes, which are separated from each other. When the disk rotates, water is captured and untwisted in the cavities of the disk, after which, due to centrifugal forces, the liquid under pressure is supplied to the outlet pipe and enters the consumers. During the operation of the blades in the pump housing, a kind of vortex movement is formed, which ensures the continuous capture and supply of water. Due to this principle of operation, the pump is called a vortex pump.

  • Pros: This type of pump provides excellent water pressure and works at maximum simple principle, and also they are the most common and budget.
  • Cons: For high-quality and long-term operation, the suction water must be as clean as possible, otherwise the device may quickly fail or lose its power. Also, such models can create significant noise from the operating blades.

Centrifugal borehole pumps are used to supply a clean liquid with a small amount of abrasive, which should not exceed 180 grams per cubic meter.

The pump works according to the following principle: water enters a rotating wheel with blades. After that, centrifugal forces act on the liquid, and a vacuum is formed inside the wheel, and pressure is formed along the edges, which pushes the water with great force. The pump housing is made in the form of a snail, this is done to increase the swirl of water and increase the pressure in the system.

  • Pros: This type of pump is very productive and reliable. They can work long time and at the same time they do not heat up, and providing a large pressure is carried out at depths of up to 60 meters. Also, the device has protection against overheating and emergency shutdown to prevent equipment damage.
  • Cons: These pumps do not have obvious disadvantages, and the reviews about them are extremely positive. The only negative may be the price and quality of parts, on which the cost of the product depends.

Screw borehole pumps 90V and 100V are designed for pumping water from wells, large tanks, reservoirs and even shaft wells. The maximum allowable degree of water pollution can be 250 grams of abrasive per cubic meter.

Screw pumps work according to the following principle: there are two screw pairs in the device case, one of which is stationary, that is, it is a stator and is made of rubber. The second spiral is a rotor and is made of a special alloy of steel coated on it. During rotation, friction points are formed between the rotor and the stator, which create fluid pressure. The more contact points, the higher the performance and working pressure.

  • Pros: Among the positive qualities, one can single out greater reliability and performance, as well as the noiselessness and depth of the device.
  • Cons: CH-90V and CH-100V are the most expensive, because they require high quality materials and protective equipment, since the devices are often used in polluted reservoirs, wells with a high sand content, etc.

Pump Selection Criteria


  • Depending on the diameter of the well, the size of the pump is also selected, taking into account the fact that it must enter the pipe with a gap (at least 10-15% of the diameter of the well);
  • In accordance with the depth of the well, the operating capabilities of the pump are also selected.

Advice! It is better to take a more powerful pump due to the fact that over time, the apparatus will weaken from the abrasive agents present in the water;

Important! With an increase in the immersion depth of the pump, its performance decreases;

  • Regardless of the pump model, automatic protections must be present in it. For example, all models of Whirlwind pumps have a thermal switch in their arsenal, which is triggered when the device heats up to a temperature of 110 degrees. Also, some models have protection against clogging.
