Borehole pumps are used to provide residential and industrial premises with water. They operate at great depths with full immersion in water over 50 meters. The powerful power plant allows water to be supplied uninterruptedly from wells and deep wells. A domestic example with high quality is the Vortex borehole pumps.

The principle of operation and types of pumps Whirlwind

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

• centrifugal;
• screw;
• vortex devices.

The centrifugal submersible pump lifts drinking water from a depth of up to 50 meters. At the same time, it 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 "Vortex SN-50N".

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

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

On devices of this type, special thermostats are installed, which, in the event of an overload of the electric drive, turn it off.

Screw pumps maintain the 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.

For the well, it consists of a thin cylindrical body connected to an electrical power plant. Inside the body there is a screw mechanism, which consists of a steel rotor (screw) and a rubber stratum (inner rubber gasket of the body with ribs). As a result of immersion to a depth, water is supplied to the chamber of the screw mechanism.

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

This principle of operation is used on the "Vortex SN-90V" and "Vortex SN-100V" vehicles.

Only suitable for ponds with a 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 disc inside. The work is provided by an electric motor.

When submerged, water enters the disc chamber through the inlet. Driven by an electric motor, the paddle disk creates a vortex flow of water along the walls of the housing. After that, it is pushed into the outlet by centrifugal force.

This class includes the "Whirlwind CH 100" and the more efficient model "Whirlwind SN-50".

Model range of downhole apparatus of the "Whirlwind" type

In terms of their performance and scope of application, the following borehole pumps "Whirlwind" stand out:

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

The "Vortex SN-50 N" apparatus is designed to pump water resources out of 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 deteriorate. The apparatus is made of chrome-plated steel. Equipped with a thermostat with a forced shutdown system.

The model has the following specifications:

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

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

The technical characteristics of the device are as follows:

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

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

Working qualities of the borehole pump Whirlwind SN 90b:

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

With the help of the Whirlwind SN 100V pump, you can pump out water masses from mines, deep pits and wells. In this case, the cross-section of the hole must be at least 120 mm in diameter. Like the previous submerged model, the CH 100B is equipped with additional hook rings, which allow safer use of the device when diving. The body is made of stainless and partly chrome-plated steel. Equipped with a thermal relay with the ability to disconnect in case of too high load.

Specifications:

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

Not so long ago, a model appeared on sale that provides the deepest (in the model range) water withdrawal from a depth of 135 meters. Pump Whirlwind SN-135, like the 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 the rest of the points, the description repeats the previous model.

How to choose the right pump for you?

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

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 the theoretically correct one. Since the high percentage of abrasive substances significantly reduces the capabilities of the device.

In some complete sets of models, special filters and purification systems are built-in, which protect the mechanisms of the device from the action of sand. This option is more expensive, but has a significantly longer service life. Also, when buying, you should definitely check the presence and operating condition of the thermostat, which turns off the device when the engine reaches a temperature of 110 degrees.

How to install the Vortex borehole pumps correctly?

Correct installation of the pump will keep its performance and functionality longer. To do this, you need to adhere to 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 body of water, the distance to the surface of the reservoir must be at least 4 meters. The distance from the device to the bottom is at least 60 cm. When installing the mechanism, you should not rely only on the water supply channel. Fix the ends of metal cables with a small section on the device body, and fix 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" 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 they can be used to organize water supply to 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 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 the distinctive features of the designs. The centrifugal pump "Whirlwind" differs from the vortex only in the impeller with blades. In centrifugal ones, they are curved, which is why, getting on them, water immediately bounces to the periphery, where a high-pressure area is formed. A low pressure area will form in the center of the wheel. 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 bends. This design allows you to create vortexes of water 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 internal cavity, which is the screw. There is a small gap between them, through which the pumped liquid moves. It should be noted that the Vortex screw well pumps are not as popular as the two previous models. They are more expensive, however, they have good efficiency, and fairly high technical characteristics. For example, 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 people may think that this is not the most important indicator, and they 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 is a small number of popular models that are used today by residents of suburban settlements. Let's consider two of them. By the way, it should be noted right away that units of this type are marked with 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 submerged to a depth of 35 m.
• Its productivity is 25 l / min.
• Head - 90 m.
• Electric motor power - 0.55 kW.
• The package includes 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 also has some drawbacks. For example, studs and lugs 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 to pump not very pure 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 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 Vortex borehole pumps. 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 country house with several 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.
• Electric motors of different sizes used in different models guarantee a decent enough head. In any case, the minimum of them is 40 m, this is the optimal indicator for household pumps of a borehole type.
• All Vortex borehole pumps are designed for frequent switching on and off, which is an important indicator for units of this type. Especially if the pumps do not operate as part of 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 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 model range

Installation rules

Like all borehole pumps, the "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.

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 your attention - a device with optimal qualities for use in summer cottages and adjacent territories. Judge for yourself.

Where is applied

Vortex SN-90V is used mainly for gardening needs and water supply for domestic 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 treated 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. All threaded connections are sealed with suitable materials. The socket 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. With the end of the summer cottage, the pump rises to the surface, drains, dries and stores in a place devoid of sunlight. Vortex SN-90V does not require special conservation.

Eugene H.

Pluses: Value for money

Disadvantages: The studs for which the pump is attached 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 7,000 rubles. In May, he lowered it into a well (18 meters). Until October, they used it in a simple mode - plugged in the plug - pumped up the containers - removed the plug from the socket. No problem. I decided not to get it for the winter, hung in the water all winter. In May 2016 he took it out for external examination. The fastening studs are completely rusted. The stainless steel body is normal. They also installed it in an automatic system with a hydraulic accumulator and a pressure switch. I worked well for the season, no problem. The only remark - when there were cold evenings and at the dachas everything was turned on, it did not work due to a decrease in voltage in the network. But then, at some point in the growth of tension, it worked again. It is necessary to put a voltage stabilizer, but my hands have not yet reached. In general, for 5200, for which you can now buy it, a good option for a summer residence. Enough for two seasons. (maybe more, but you probably need to lift it - disassemble, service, change the studs, reluctance) I think to buy a couple, as a consumable, change the norms every two years. :-) There was a little bit of very, very fine sand in the well - it didn't affect the work in any way.

Pluses: PRICE! this is the most optimal offer on the Internet. Good performance

Commentary: I don’t know why there are so many bad reviews, but we will give the same to the parents at the dacha, the performance is 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, put a check valve and immediately change the studs to stainless steel and you will be happy.

Rating: 5 out of 5

Advantages: From 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 that kind of money.

Commentary: the sand in the well haunts that soon you will still have to buy a new one. but I have already worked for 4 years, I'm happy.

Rating: 4 out of 5

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

To provide residential and industrial premises with water far from the main water supply main, drilling of a well 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 Vortex 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

Depending on the features of application, performance and other performance characteristics, several versions of the Vortex submersible pumps are distinguished. The company produces models with an upper water intake, designed for highly contaminated sources, and with a lower one, which are used in wells with clean water. Apparatus with units 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 screw electric 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 a 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);
• stationary 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, 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 height 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 demanded models of the series stand out:

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 operates on the basis of 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. The technical characteristics of the device 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 vortex SN 60V borehole pump, 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 home water supply system, and for watering a garden or vegetable garden. The suction of the liquid is carried out in the area where the housing is divided 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 entering the device 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 borehole diameter 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 pure liquid. As in the previous versions, the case is made of stainless steel. The lid of the device is equipped with cable eyelets. The high-performance 1100 W motor features an ipx8 protection class. 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 / 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 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.
