What can be cooked from squid: quick and tasty

The process of raising water from wells, well shafts and other sources is carried out with the help of deep pumps. There are many models, as well as the characteristics by which the acceptability of a particular unit is assessed. The Vortex SN-90V is presented to the attention - a device with optimal qualities for use on summer cottages and adjoining territories... Judge for yourself.

Where is applied

Vortex SN-90V is mainly used for gardening needs and water supply for living conditions- home water supply, bath. It is forbidden to use the unit under the following conditions:

• Pumping out septic tanks.
• Emptying of reservoirs during the period of seasonal or natural flooding - basements, storm drains, gutters.
• Emptying containers with acidic, alkaline or other aggressive chemicals.

From the list, we can conclude that the pump is picky about the quality of water - it should not contain sand and impurities.

Specifications Vortex SN-90V

The unit operates from a home voltage network of 220 V and 50 Hz. Electric motor power - 550 V. Target tasks performed by the pump:

• Water rise - 90 m.Diving depth - up to 35 m.
• Productivity - 1.5 thousand l / h.Diameter of the supply hole - 9 cm.
• Water temperature - up to + 35 C.
• The casing and the pumping part are made of machined metals - stainless steel and chrome plated steel.

Well connection

The manufacturer provides the user with assembly instructions and recommendations for use.

The items are as follows:

Preparation for work

According to the assembly scheme, the pump body is connected to the pipeline using couplings, adapters, elbows, tees and others. Everything threaded connections condense suitable materials... The outlet from the power source is pre-installed in an area protected from moisture and splashes. A cable is attached to the eyes of the unit, a power cable is attached to the outlet pipe. Lower the structure carefully, without stressing the cable and stressing the riser pipe. The cable is fixed at the head of the well.

Inclusion and prevention

It remains to connect the pump with a plug to the power source and control the water quality. In the case of a dirty or turbid flow, it is recommended to check the position of the pump relative to the bottom and the water mirror - not lower than 60 and not higher than 50, respectively.

If network drops are not uncommon, it is important to purchase a voltage stabilizer. Higher or lower mains values ​​will reduce the service life of the device. At the end of the summer season, the pump rises to the surface, drains, dries up and stores in a place devoid of sunlight. Vortex SN-90V does not require special conservation.

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 the aggregates of this type today they have become very popular, because they can be used to 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 wells in suburban areas today began to appear more and more often in relation to wells. And even the complexity of their construction does not repel the owners of country houses.

It is necessary to speak about submersible pumps "Whirlwind" of borehole type as 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.

Well pump "Whirlwind"

Varieties of pumps "Whirlwind" for wells

To begin with, the manufacturer today offers several purely design positions. That is, all the proposed models are divided into three groups:

• centrifugal pumps;
• vortex;
• screw.

Attention! Immediately, we will make a reservation that centrifugal devices are equipped with a lower water intake, vortex and screw ones - with an upper one. In principle, by this design feature, they can already be distinguished.

Centrifugal model

Now distinctive features designs. The centrifugal pump "Whirlwind" differs from the vortex only in the impeller with blades. In the centrifugal, they are curved, which is why, getting on them, the water immediately bounces to the periphery, where an area is formed high pressure... And in the center of the wheel, an area will be formed low pressure... And since the 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 bending. This design allows you to create water swirls 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 in comparison with centrifugal ones, therefore they are inferior to the latter both in head and productivity.

As for the screw units, this is a unique design in which there are two screw parts: the screw and the chamber. They repeat each other in the configuration of the inner cavity, which is the screw. There is a small gap between them, through which the pumped liquid moves. It should be noted that screw well 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 35 and.

Screw unit with top water intake

All three models can also be compared for 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 a shop comes to buy. He selects a borehole pump in terms of performance and head. And this is correct, but do not forget about the concentration of suspended particles in water.

• the 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 capricious 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 are used today by residents of suburban villages. Let's consider two of them. By the way, it should be noted right away that units of this type are designated by the marking "CH", that is, a borehole pump.

Whirlwind SN 90v

So, the "Whirlwind" SN 90v borehole pump 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 borehole diameter of 100 mm. And they, as you know, are considered the most common.
• It can be immersed to a depth of 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.
• It can pump water with temperatures up to + 35C.
• The recommended distance to the bottom of the well is 60 cm.

SN 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 SN 90v pump has some drawbacks. For example, studs and eyelets are made of plain steel, so they rust quickly. And with long-term use, they simply fail. According to consumers, after three years of operation, the pump may end up at the bottom of the well forever. The lug will corrode to the end, and when lifting 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 sinking is 35 m.

Speaking about the "Vortex" SN 90V borehole pump (its structure 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. This is probably why this model is so popular today among residents of suburban settlements. 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 "Vortex" SN 50 borehole pump. This is a centrifugal unit with a bottom water intake. Here are its technical specifications.

• Productivity - 60 l / min.
• Head - 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 from of stainless steel, the pumping 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 model line of borehole pumps "Whirlwind". For example, brand CH 60. Its diameter is only 75 mm, which allows installing the device in wells with a borehole diameter of 80 mm. That is, when deciding on the choice of a unit, it is necessary to take into account the possibility of its installation in the mine of a hydraulic structure. And if a well with a diameter of 80 mm was drilled on the site, then the pump that is optimal for it is CH-60. The two previous positions will obviously not fit into such a well.

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

Model CH-60

Key advantages of Vortex borehole 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 your attention to is the small overall dimensions of the device, at 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 multiple consumers.
• High reliability of the pump, confirmed by its degree of protection, which classifies it as IPX8. Each manufacturer sets this category himself. But there are two positions in it that are considered the standard. This is a submersion depth of at least 1 m, in which the pump must work for at least half an hour.
• Different caliber electric motors used in different models guarantee a decent enough head. In any case, the minimum of them is 40 m, this is for household pumps borehole type is the optimal indicator.
• All borehole pumps "Whirlwind" 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 a 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 sufficient to ensure the installation depth of the device. Therefore, it can be increased. The only requirement for twisting is that it must meet electrical safety requirements. The ideal solution is if the twist will be located outside the wellbore.

Variety of lineup

Installation rules

Like all borehole pumps, "Whirlwind" is installed in the shaft of a hydraulic structure, suspended by a cable. To do this, you can use nylon or metal (stainless steel) cables. The unit has specially installed eye bolts, the cable is attached to them.

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

It is very important to properly lower the unit into the structure shaft. 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 to do this.

Installation of a borehole pump

Conclusion on the topic

Summing up all of the above, we must pay tribute to the "Whirlwind" (borehole) pump. 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 this or that model, it is necessary to analyze the water from the well.

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

Submersible pump Whirlwind SN 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 body should be at least 60 cm, from the surface to the device half a meter.

Downhole products are manufactured - top-drawer pumps in 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 passport.

The casing of the deep well pump vortex SN 90V is made of stainless steel. The length of the 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 out water should be from one to 32 degrees.

The model is supplied by the manufacturer with a rubber check valve which prevents water from flowing 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 ", if necessary, you can install a transitional connection 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 forbidden to artificially reduce the diameter of the installed hose.

On the sides of the body there are special eye-bolts for fastening steel cable... With the help of a cable, the body is immersed or then retrieved from the well.

It must be remembered that in order to avoid damage to the electrical connection of the electrical cable to the terminal box, do not pull on the cable, or even handle it when the electrical network 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 Techniques, 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 above 30 mA / sec.

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

Vortex data and characteristics can be viewed in the picture.

Device

СН series constructions

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 the narrower part, which creates pressure. For what type of pumps is a very important parameter such as the speed and power of the engine: the speed of rotation creates pressure, and power is the amount of liquid ejected. The standard engine speed is 2800 rpm.

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

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

The design with a centrifugal rotor allows the transfer of microparticles up to 15 microns. (turbid water). On the other hand, the screw can pump viscous liquids, but the paddle cannot.

The device of the borehole pump Whirlwind SN 90V

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

Dependence of the lift height in the deep-well vortex pump SN 90V on the performance.

Do-it-yourself Whirlwind SN 90V pump repair

It so 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:

• Dirty water inlet holes;
• sleeve wear;
• screw wear.

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

Disassembly:

To disassemble the case, it is necessary to unscrew the four screws on the shims and the lugs with keys with a facet 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 accessible for inspection.

From the top cover, carefully, without using sharp objects (only by hand), get the check valve - the rubber must be elastic, the movable valve cover and the body must not be damaged. If there are no visible breakages, then after cleaning the coking parts or the inlet openings of the grill, the product will work as before.

Device

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

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

So your helper has started to dispense less water. Most likely a malfunction in the working bodies that come into contact directly with water is interior housing, auger and its sleeve. It is strictly forbidden to start 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, take out the auger sleeve, after which the auger itself is unscrewed. The auger is screwed into the drive shaft on a "left-hand" thread. If the thread has acidified, there are turnkey edges under the protective sleeve.

Checking the motor

Checking the integrity of the windings includes a break test and insulation measurement.
To check the continuity of the circuit, two checks are carried out:

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

To do this, you need to use a multimeter, and understand the principle of operation and the device of the vortex pump SN 90V. To measure the first parameter, set the multimeter to 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 grounding conductor is measured by touching the grounding pin of the plug and the body. 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, cable plug or wire.

The next check consists in determining the insulation value of the phase wires from breakdown to the case. For this, the measuring probe of the multimeter in the 200 MΩ mode is connected to the pins of the plug of the electric wire. the second probe to the body (the place of contact must be clean), the resistance during measurement must be at least 200 megohms.

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 clicking or crunching, the rpm should be stable. frequency of revolutions for household appliances = 2800 rpm.

Inspection of working bodies

then the auger and the 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 should enter each other with friction.
After cleaning the parts, the assembly is carried out in the 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 carry out the diagnostics professionally.

Parts washing

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

Oxides and hydroxide (rust) are removed most effectively manual method- metal brush and rinsing with water. Ideally high pressure rinsing (mini wash). The deposition of carbonate salts, which turns into carbonate minerals during deposition: 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 solution table salt... But if you decide to disassemble it to the details, it is best to supply new spare parts, especially valves and gaskets.

So, if the assistant stopped delivering water to the mountain having lost productivity, and you decided to repair the vortex pump SN 90V, then most likely it got dirty, most often it is a calcium deposit (popularly limestone). If the plaque is not yet large and has not coked up, then you can do without chemistry and you can use citric acid for cleaning. It removes organic salt plaque well.

Well pump Whirlwind SN 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 case together. After a year and a half, there is a possibility that the body will crumble right in the well. It's amazing who came up with this - a stainless steel body, steel studs tightening. I suppose that initially the studs were made of stainless steel, but in order to save money, China proposed its own version of the assembly. I also attribute to the disadvantages that it is used only for pure water. Be sure to choose a solid stainless auger, chrome plated and then wedge due to increased friction with the sleeve. Approximate service life 2-3 years. But it looks like it's worth its money.

Anonymous 2016

I refer to positive properties: oil in the motor - this gives additional electrical properties to the windings. There are eyebolts for suspension, decent head. The store announced the length of the cable is 20 meters, I did not check it, it turned out to be a little more at home. It pumps from a depth of 20 m. The pressure is good, about the same as the full opening of a tap in an apartment. I'm tired of constantly turning on and off the outlet, I'm thinking of purchasing an automatic system for starting the engine from the pressure in the water line. It has been working for six months, so far without any comments.

Sergey 2017

I regard the advantages of a small price, a high-quality assembly of a vortex pump cn 90v review is good, though low productivity, but I have a non-standard well - 100 m deep. I consulted the sellers, they said that this type does not work for a deep well. I use it for a set of containers. Suspension on 6 mm cable. The length of the cable when purchased was 20 m, the consultant said that it can be increased. I cut the cable near the plug, built it up, nothing, it works normally for a year and a half, no complaints. Three-core cable in rubber, silk threads and braid inside.

You can buy the Vortex SN 90V in specialized dealerships, 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 with water far from the main water supply main, well drilling is used. In this case, the supply of liquid from a deep source is carried out by downhole pumps. This type of pumping technology is distinguished by a high pressure characteristic, continuous flow and a long service life.

Among the domestic models of apparatus for the 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 apparatus Whirlwind and their features

Several options are available depending on the application, performance and other performance characteristics. submersible pumps Vortex. The company produces models with an upper water intake, designed for highly polluted sources, and with a lower one, which are used in wells with clean water. Apparatus with assemblies made of steel, brass, and durable polymers are distinguished according to the materials used. Mechanical seals in such devices are made of graphite or ceramic.

One of the main criteria for the distribution of Vortex downhole pumping devices 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

The electric screw pump is a fairly versatile model. Such an apparatus can be used not only in wells, but also in wells, mine reservoirs, open reservoirs. Due to its design, the device is capable of passing liquids with a solid content of up to 250 g / cc. m. Models of this type support head 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 case, a working chamber, an electric cable and an eyelet with a 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 an external thread. The helical threads of both elements are offset from 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 openings to the outlet. The total head 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, convenient repair or maintenance. In addition, the device can be used in both horizontal and vertical orientation, which expands the range of applications.

1.2 Centrifugal downhole unit

As in the case of auger models, the centrifugal apparatus consists of an engine compartment and a working chamber, combined in one housing. Only the design of the working chamber of the device differs. It is a volute-shaped diffuser, inside of which a wheel with blades rotates on the 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 the displacement, an area of ​​discharged pressure is formed at the inlet of the apparatus, which leads to the suction of a new portion of water. In contrast to this, the pressure rises under the walls of the cochlea, which ensures a high head. Selected versions can 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 distinguished by high productivity and wear resistance of the units. To prevent overheating of the unit, most centrifugal models are equipped with an automatic emergency shutdown system.

1.3 Vortex deep unit

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

Due to the thinner design and small clearances between the impeller and the casing, the vortex unit has a capacity of only 40 g / cc. m. Protection from larger particles is provided by a strainer installed on the suction openings. The head of the vortex apparatus is over 100 m, which makes it possible to mount it 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 The 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 in the series are:

The CH 50 model is a vortex downhole tool with inlets at the top of the casing. The apparatus is made of stainless steel, and the cross-section of the body allows mounting СН 50 in a well with a minimum diameter of 100 mm. Liquid intake is carried out 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 is that the CH 50 N centrifugal apparatus is equipped with a lower water intake. Specifications devices have the following meanings:

• the maximum productivity of the model is 3600 l / h;
• lifting of liquid is carried out 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 the borehole pump Vortex SN 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 a domestic water supply system and for watering a garden or vegetable garden. The suction of the liquid is carried out in the area of ​​separation of the housing into the motor and working chambers (in the middle part). On the top cover of the body there are lugs for the cable, with which the CH 60V is fixed in the headband 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;
• volume of pumped liquid per hour - 3000 l;
• motor power - 800 watts.

The complete set of the Vortex SN 90V borehole pump is supplemented with a thermostat and a check valve, which prevents water from getting back into the device after it is turned off. The device belongs to screw models and is suitable for work with clean water. The minimum diameter of the well into which the apparatus is mounted is 100 mm.

The main performance characteristics of the borehole pump Vortex SN 90b:

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

Water in the screw pump Vortex СН 100В is sucked in through the holes in the upper part of the housing. The screw working mechanism allows you to work exclusively with clean liquid. As in the previous versions, the case is made of stainless steel. The cover of the device is equipped with cable eyelets. The powerful 1100 W motor is IPx8 rated. The performance characteristics of the model are as follows:

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

The most productive model of the series is the Vortex CH 135. The device belongs to the centrifugal type of pumps. In addition to the well, the device can be mounted in open water bodies, reservoirs, shaft wells. Sensitive units of the apparatus pump liquid containing abrasive particles up to 40 g / cc. 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 range and provides a capacity of up to 5700 l / h. In this case, the temperature of the liquid should not exceed 35 degrees, since the motor begins to overheat. In such a model, the height of the liquid supply is 135 m, and the pump itself deepens into the thickness of the liquid by 60 m. Water intake is carried out by suction holes in the central part of the housing. The minimum borehole section for the apparatus is 102 mm.
