Types and models of borehole pumps whirlwind. Model range of borehole pumps "Whirlwind" How to properly install borehole pumps "Whirlwind"

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 that prevents water from pouring back into the tank 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, when the blades rotate, they capture water in the widest part of the chamber and move it to a narrower one, which creates pressure. For which type of pumps, a very important parameter is the speed and engine power: the rotation speed creates pressure, and the power creates the amount of ejected liquid. 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, the operation of such a product is allowed only with clean water, so that abrasive sand or solid particles do not damage the surface of the sleeve 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 driven by the electric motor pushes water along the rubber walls of the housing, creating pressure at the outlet

Dependence in the deep pump whirlwind sn 90v lifting height on performance.

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 the inner part of the housing, the auger and its sleeve. 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 experts will diagnose professionally.

Parts washing

During long-term operation, depending on the chemical composition of the water, less and more often the body and parts are exposed to mineral deposits, and simple 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 use citric acid for cleaning. 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. I'm tired of constantly turning the socket on and off, I'm thinking of purchasing an automatic system for turning on the engine from the pressure in the water mains. 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.

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

In the model range "Whirlwind" there are 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 according to the simplest principle, and they are also 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 for a long time and do not heat up, and high pressure is provided 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.

Model Specifications

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.

Repair of the pump "Whirlwind":

Rating: 5 out of 5

Advantages: naosu pumps perfectly for 2 years

Disadvantages: the studs that attach the pump to the motor are made of black metal, after six months the water ate them .. they must be made of stainless steel !! The fastenings to the rope were also eaten by water .. everything must be made of STAINLESS STEEL .... A PAINFUL PLACE OF THE HAIRPIN

Comment: overall the pump is excellent NO PROBLEMS

Rating: 4 out of 5

Eugene h.

Pros: Value for money

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

Comment: I took it on the market in the Moscow region in May 2015 for 7000 rubles. In May, he lowered it into the well (18 meters). Until October, they used it in simple mode - plugged the plug into the outlet - pumped up the containers - removed the plug from the outlet. No problem. I decided not to get it for the winter, I hung in the water all winter. In May 2016, he took out for an external examination. The studs are completely rusted out. Stainless steel body is ok. They mounted it in an automatic system with a hydraulic accumulator and a pressure switch. Worked well for the season, no problems. The only remark - when it was cold evenings and everything turned on the heating in the dachas - it did not work due to a decrease in the voltage in the network. But then, at some point, the voltage increased again. It is necessary to put a voltage stabilizer, but the hands have not yet reached. In general, for 5200, for which you can now buy it, a good option for giving. Enough for two seasons. (maybe more, but you probably need to raise it - disassemble, service, change the studs, reluctance) I think to buy a couple as consumables, change every two years, normal. :-) There was a little bit of very, very fine sand in the well - it did not affect the work in any way.

Rating: 5 out of 5

Pros: PRICE! This is the best deal on the internet. Good performance

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

Rating: 5 out of 5

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

Disadvantages: only pluses for such money then.

Comment: the sand in the well does not give rest that soon you will still have to buy a new one. but I have already worked for 4 years, I am satisfied.

Rating: 4 out of 5

After five months of use, the studs rotted, so if you take it, immediately change it to stainless steel. And so a good pump. It will go in the country.

Borehole pumps are used to provide residential and industrial premises with water resources. They operate at great depths with full immersion in water over 50 meters. A powerful power plant allows you to supply water uninterruptedly from wells and deep wells. Whirlwind well pumps are a domestic example with high quality.

The principle of operation and types of pumps Whirlwind

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

• centrifugal;
• screw;
• vortex devices.

The centrifugal submersible pump lifts drinking water from a depth of up to 50 meters. At the same time, he copes with the concentration of sand up to 180 grams per cubic meter. The device is quite powerful and provides uninterrupted water supply. These pumps include "Whirlwind CH-50N".

In its structure, it 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 immersed, the pump freely passes water into the body and it fills the entire space between the blades.

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

On devices of this type, special temperature controllers are installed, which, in the event of an 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 water surface 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.

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

Under the action of the electric drive, the internal screw is wrapped inside the strator. Contacting together, the friction pair forms sealed spaces, which are maintained until the release of water into the pipeline. The next portion of water increases the pressure and throws the water mass even higher.

This principle of operation is used on the Vikhr SN-90V and Vikhr SN-100V apparatuses.

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

When immersed, water enters the disc chamber through the inlet. Driven by an electric motor, the disc with blades creates a vortex flow of water along the walls of the hull. After that, it is pushed out into the outlet pipe under the action of centrifugal force.

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

The model range of downhole devices of the "Whirlwind" type

According to their working qualities and scope of application, such borehole pumps "Whirlwind" stand out:

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

The Whirlwind CH-50 N device is designed for pumping water resources from wells and pits, the depth of which does not exceed 50 meters. In this case, the drilling of holes in the reservoir should be at least 10 cm. The device is suitable for working with water without impurities. In medium and heavily polluted water bodies quickly become unusable. The device is made of chrome-plated steel. It is equipped with a temperature regulator with system of compulsory shutdown.

The model has the following specifications:

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

When using a borehole pump SN 60v, it is possible to 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 stainless steel. Suitable for water with an admixture of abrasive materials not higher than 40 grams per cubic meter.

The technical characteristics of the device are as follows:

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

The immersion depth of the borehole pump Whirlwind sn 90v is much higher than the previous models and is 90 m. For easier immersion in the well and extraction, the chrome-plated steel body is equipped with special hooks to which a cable or rope is attached. The optimal distance from the surface of the water mass to the device is 35 m. With a deeper placement, negative pressure is exerted on the nodes of the mechanism.

Working qualities of the borehole pump Whirlwind sn 90b:

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

With the help of the Whirlwind sn 100v pump, water masses can be pumped out of 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, the CH 100B is equipped with additional hook rings that allow you to use the device more safely when diving. The body is made of stainless and, partially, chrome-plated steel. Equipped with a thermal relay with the ability to turn off in case of too high a load.

Characteristics:

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

Not so long ago, a model also appeared on sale that provides the deepest (in the model range) water extraction from a depth of 135 meters. Pump Whirlwind CH-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 watts. 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 buying 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 apparatus surface. 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, CH-90N and CH-100B and CH-135 will be optimal.

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 higher than theoretically correct. Since a high percentage of abrasive substances significantly reduces the capabilities of the device.

In some complete sets of models, special filters and cleaning systems are built in, which protect the mechanisms of the device from the action of sand. This option is more expensive, but has a much longer service life. Also, when buying, 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 Whirlwind well pumps?

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

When deepening the apparatus into the water mass, 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 channel. Fix the ends of metal cables with a small cross section on the body of the device, and fasten the free ends at the exit of the well.

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

Whirlwind pump repair (video)

The domestic manufacturer of various pumping equipment under the brand name "Whirlwind" today offers 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 it is possible to organize water supply for 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 wells in summer cottages today began to appear more and more often relative to 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. In principle, by this design feature they can already be distinguished.

centrifugal model

Now the distinctive features of the designs. 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 of ​​low pressure will form. 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 performance.

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, for centrifugal pumps, the maximum head is 50 m, for screw pumps, 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.
• Operates on 220 volt alternating current.
• Can pump water up to +35C.
• The recommended distance to the bottom of the well is 60 cm.

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.

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 water to a small country house with several consumers.
• 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.
• Different-sized 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 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 a pumping station or without a 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.

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.

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.
