Borehole pumps water cannon technical characteristics. The success of the Russian manufacturer - borehole pump "Vodomet

Vodomet pumps are submersible multi-stage devices of the Russian company Dzhileks, designed to provide autonomous water supply to houses and watering plots.

Production is located in Klimovsk, Moscow region.

Equipment Features

The equipment of this brand is a range of household appliances of various sizes and different capacities, so you can choose a model that will provide the required amount of water.

Advantages of submersible pumps:

• work quietly;
• are small in size;
• do not "trouble up" water, unlike vibration ones;
• small size;
• low price;
• high efficiency;
• reviews of submersible pumps Vodomet are mostly positive - there are practically no negative ones, which is also a significant indicator;
• the ability to work in water with a significant amount of sand or clay (from 2 to 5 kg / m 3).

Water pumps Vodomet, designed specifically for Russian operating conditions, are of two types:

• wells;
• borehole (deep).

What are their differences?

Pumps for wells Dzhileks Vodomet are designed for use in relatively shallow wells (8-10 m), tanks or open water.

A prerequisite for the operation of such a pump is the sufficient width of the reservoir so that not only the pump, but also the float switch can fit there.

The water cannon pump for the well has obvious benefits before the well:

• larger ratio useful action, which means that, other things being equal, the submersible water jet pump for wells will have a greater performance than the water jet pump for a well;
• less sensitivity to dirty, "sandy" water;
• the presence of a simple float switch, thanks to which there is no need to install protection against "dry" operation;
• low price - from 9,000 to 13,000 rubles.

The submersible water pump for wells is smaller in size and is designed for extracting water from narrow (from 100 mm) and deep wells, lifting water from a considerable depth (usually the depth of wells is from 40 m).

The price of pumps for water jet wells is slightly higher than the price of well pumps - from 10,000 to 24,000 rubles.

About manufacturer's models

Submersible pumps Vodomet are available in several modifications, differing in power and other technical characteristics. Pumps for wells are marked as follows: pump Vodomet 55/35A, 55/50A, 55/75A, 150/30A, 150/45A, 150/60A.

Here, the letter "A" indicates that the pump is equipped with an automatic float switch.

Well pumps have the following designations: Water jet pump 40/50, 40/75, 60/32, 55/35, 55/50, 55/75, 55/90, 110/110, 115/115.

• The first number indicates the pump's maximum outlet flow (l/min). This flow rate is determined with open taps and no resistance to water movement.
• The second number is the maximum head (m), which develops the device with fully closed taps.

For example, the submersible pump Vodomet 60/32 delivers up to 60 liters of water per minute with a free spout, and when the water consumption taps are closed, it can create a pressure of up to 32 m. This unit costs almost 6800 rubles.

Based on the technical characteristics, we can say that:

• Water jet pumps with a maximum possible flow rate of 60 l/min will work most efficiently in water supply sources with a small flow rate (the amount of water that a source can give per unit time). In this case, the flow rate of the source must be no less than the performance of the pump, otherwise the pump may pump out all the water in the well (well), and begin to draw in silt or work “dry”, which can lead to its breakdown.In real conditions, a submersible pump Vodomet 60/52 at a price of about 8000 r can provide a consumption of 35-40 l / min (more than 2 m 3 / hour) - up to 4 consumer taps at the same time. The submersible pump Vodomet 60/72 at the price of 10,000 r will give a stronger pressure at the same flow rate. Thanks to this, with the help of such a pump it is possible to move water over a greater distance.
• Pumps Vodomet with the highest flow rate of 115 l / min, provide for use in wells with medium and high flow rates, with a possible water flow rate of up to 65 l / min (about 4 m 3 / h). The submersible pump Vodomet 115/115 is one of the most powerful borehole pumps in the line. Its power is about 2200 kW, and the price is 16,000 rubles.
• Pumps Vodomet with a flow rate of up to 150 l / minute are necessary for the water supply of large houses. Such pumps can only be used in wells with a high flow rate, and their use is advisable when the water flow is high - more than 4 m 3 / h.

More accurate data for selection is easy to calculate on your own. The required pressure of the pump is the sum of the values ​​of the required pressure in the taps of consumers, possible pressure losses in pipelines and the height difference between the source and consumers.

Roughly, the maximum pump head can be determined by measuring the distance from ground level to water level in a reservoir:

• if the specified distance is less than 5 meters, then a pump with a head of up to 35 m is suitable. For example, a submersible pump Vodomet 55/35;
• if the distance is from 5 to 25 m, then a device with a declared head of 40 or 50 m is suitable. For example, a submersible pump Vodomet 60/52;
• if the distance is 25 - 45 m, you should choose a model with a head of 60 or 75 m. For example, a submersible pump Vodome 60/72;
• if the distance is from 45 to 60 m, it is better to choose a device with a pressure of 90-150 m. For example, a submersible pump Vodomet 115/115.

Device Reviews

Water pumps Vodomet are very popular with owners of private houses and summer cottages, so a variety of reviews have been accumulated about pumps for Vodomet wells.

Since the submersible pump for the water jet well is not deprived of attention and there are enough reviews about it - let's give a few for an example.

Maxim Viktorovich, 41 years old, Podolsk:

I have had a submersible water pump for the fifth year. Installed in a well at a depth of 25 meters. It works and works, the pressure is normal, only sometimes there is not enough water for everyone.

At first, I thought that my sandy well would "kill" the Vodomet well pump in a couple of years. I don’t know about others, but everything suits me. I'm thinking of looking at a more powerful model.

Maria and Alexander Semenov, Kursk:

Considered different variants for supplying water to the country house. We chose between Ukrainian Aquarius and Russian Gileks. Aquarius, they say, is very sensitive to sand, a remote condenser is also inconvenient. In general, we settled on a submersible pump Vodomet 60/52.

It turned out that it gives 52 l / min only in ideal conditions, but in fact it comes out two times less. Nobody warned us about this. Would have known in advance — bought more powerful.

Mikhail Viktorovich, 61 years old, Ufa:

Reliable, good device. A submersible well pump Vodomet has been installed in the well for more than three years. It extracts water from eight meters and in a straight line about 35 meters more. Disadvantages - it is bad to connect through the RCD (often knocks out) and the cables are short.

About the device

The pump, completely immersed in water, works in very difficult conditions. Despite research, testing and the latest developments, these devices often fail. The causes of breakdowns are very diverse, but the main ones are:

• installation and operation of the pump in violation of the manufacturer's recommendations;
• voltage drops;
• dirty, sandy water;
• mechanical wear of parts of the mechanism - housing, blades.

In order for the Water Jet water pump to work properly for as long as possible, it must be installed correctly. So, when installing a pump in a well, it is necessary to mount it in a casing pipe with inside diameter not less than 100 mm.

The upper part of the pipe is closed with a cap to prevent foreign objects from entering the well.

To prevent the device from freezing in winter, a closing well is installed above the well, and the main pipe to the house is buried in the ground below the freezing level. The pump is installed so that it is lowered into the water, but not closer than 1.5 m to the bottom of the reservoir.

The schematic diagram of connecting the Water Jet pump is no different from the nuances of installing any other pump for a well - tied to a cable, it sinks to the bottom of the well. Attached to the cable with staples power cable and a hose through which water will flow.

After the device is at the bottom, the cable should be firmly fixed at the top.

A big plus is that do-it-yourself repair of the Water Cannon pump is quite possible. For a successful repair, you will definitely need spare parts to replace the damaged ones.

If "guilty" - circuit diagram water jet pump - the capacitor may have failed. If the water from the tap began to flow worse, the filter may be clogged or the hose is damaged (and the water simply flows back into the well).

The internal structure, the procedure for disassembling and repairing the Water Jet pumps are indicated in each instruction for the device.

However, it should be noted that it is not recommended to engage in such work on your own - despite the simplicity of the design, its disassembly and assembly (especially) requires some experience.

Equipment overview (video)

It is not enough to dig a well or a well. You should take care of how to supply water to the house, garden and other places. The water pump is designed for this purpose. The pump manufacturer is Dzhileks, a domestic leader in the manufacture of water pumps and related equipment.

Where can I use Gilex Water Cannon:
open waters,
wells,
wells,
various water tanks.

From the sources, water is supplied to the automatic water supply systems of the house, for watering the garden and garden, or for other purposes at the discretion.

Due to the layout features, the Gileks Vodomet pump can be placed at a depth of 100-150 mm from the water surface, and can also be used in a horizontal position. It is perfect for working in open and shallow sources.

How does a water pump work?

All Gilex models have a similar device principle. The stainless housing houses the pump part and the electric motor, which is washed by water. The rest of the parts are fixed with an intermediate support. The case is closed with covers on both sides.

The pump motor is filled with oil. The thermal relay is located outside the oil-filled cavity, which simplifies the repair of the part.

Depending on the model, the Waterjet pump may have different number repetitive steps. The parts of the device are divided into four components:
Cup.
The bottom of a glass.
Anti-friction washer.
Impeller.

The impellers rotate in the glass. And the cylinders are fixedly fixed between the cover and the plastic ring.

Device advantages

The manufacturer took care of human health. All parts of the Gileks water jet pump that come into contact with water are made of environmentally friendly and safe materials that do not affect water quality.

Some models of the Jilex Water Jet device have a removable filter. Its purpose is to protect the system from dirt, clay and sand. The filter extends the life of this equipment. If it gets dirty, you can clean it yourself. Also, the fence mesh has a large area. Water will fully flow even if the pump was lowered to the very bottom of the source.

The bottom cover has a conical shape. This design makes it easier to submerge the pump, it will not cling to possible casing connections.

The power cable can be pulled through the cover on top of the pump. Thanks to new design device it can be effectively used in wells with a small diameter casing pipe.

The engine of the Gileks water jet pump is cooled thanks to the duct cold water between stator and housing.

Automation, which is built into the pump system, excludes its operation in idle mode. This function protects the engine from overheating, which prolongs its service life.

The thermal relay built into the pump motor determines the oil heating temperature and, if the norm is exceeded, stops the operation of the device.

In order to ensure uninterrupted operation of water production, it is necessary to install special equipment. Pumps Dzhileks Vodomet for pumping water, you can install with your own hands near the mouth of a source of drinking or technical water.

In addition, Dzhileks Vodomet pumps for pumping water from a well can be immersed under the surface of the water table. This one is able to extract the required volumes of water from a do-it-yourself well and supply it to the house, outbuildings, greenhouses or gardens.

1 What is the design of Dzhileks Vodomet pumps?

The Gileks Water Jet pump for water extraction is presented in the form of a multi-stage unit, the principle of operation of which is based on the active use of centrifugal force. All Dzhileks Vodomet pumps for pumping water are equipped with floating wheels and a washed motor. A do-it-yourself unit can reliably supply water from:

• reservoir;
• open reservoir;
• Wells.

Due to the presence of floating wheels, the Dzhileks Vodomet pump for pumping water has enough high rates hydraulic efficiency. Reviews about such a pump, for the most part, are only positive.

The technical characteristics of the Jilex Vodomet devices are quite high, this is also evidenced by user reviews. Thanks to a number of design improvements, the Dzhileks Vodomet pump has a fairly compact axial dimensions of the body and a low weight of all rotating working elements.

The consequence of all this is a significantly reduced level of vibration of the unit during its operation. In addition, it will not be difficult to disassemble such a pump with your own hands and repair it.

The use of floating wheels in the pump contributes to the minimum number of blockages that occur due to the ingress of large particles into the system.

In addition, the electric motor of the pump is well protected against sudden overheating. The characteristics of the device allow washing the engine with a stream of water in order to cool it.

In addition, the presented pump can be installed in the well with your own hands. Repair of this unit can also be done by hand.

Feedback on the installation of the pump with your own hands and how it was repaired will help you figure out how to properly carry out the procedure for such work.

The engine is located above the pumping part of the device. Such a feature constructive solution allows you to output the power cable directly from the .

Thanks to this, the pump can be mounted in a well with a minimum working diameter, and it can be easily repaired if necessary.

It should be noted that the presented layout of the pump has proven itself well in cases where the design is used and when it is partially submerged.

The unit itself consists of two main parts - this is the engine and the pump compartment, which is located in a common housing. All other moving parts and elements of the unit are centrally fixed in the housing using a special intermediate support.

It also uses the front and back covers. The pump is designed in such a way that the floating wheels included in it can approach each other.

Due to this, there is a significant reduction in the gap between the parts of the device that are in a movable state and the fixed parts.

This solution avoids the occurrence of internal leaks and, in general, has a positive effect on increasing the efficiency of the entire system.

All presented units, depending on the types of marking, have a different number of repeating steps. All parts in the device are divided into four subspecies. This:

1. Impeller.
2. Cup.
3. The bottom of a glass.
4. Anti-friction washer.

The glasses are made in the form of cylinders made using black polyamide. Each of them is equipped with a belt that rests against the ring.

The ring is inserted into the spacer located in the body. An anti-friction washer is located between the glass and the impeller; it is designed to prevent friction of the mechanism parts.

The whole system is based on the rotation of the impellers located in the glasses. The cylinders are fixed and do not move due to the fact that they are fixed between and the cover.

1.1 Types of models

All units are divided into three main categories. These can be pumps for extracting water from a well; a special cooling jacket is supplied with such devices.

In most cases, the systems are used in the arrangement of private houses or summer cottages. Downhole type units are used to provide water supply from those wells that have a large diameter.

In addition, such pumps are used in all kinds of tanks and reservoirs. Chastotnik type systems are widely used in areas where uninterrupted water supply is required in automatic mode.

As a rule, these are cottages and summer cottages. An important advantage of such a device is the ability to provide the desired level of pressure in the entire water supply line.

The pressure level is not affected by the number of points from which water is drawn. Feedback on pumps is mostly positive.

1.2 Specifications and reviews

2 The most common malfunctions and their repair

One of the most common unit malfunctions that require repairs is that when the device is turned on, the pump does not pump water.

If you listen carefully, you can sometimes hear a barely noticeable buzz. Sometimes the device does not make any sounds at all and can be shocked at the moment when the user touches its case.

All these signs indicate that there was a partial abrasion of the covers located between the stages and the impellers. In order for the unit to work again, it must be completely disassembled and worn out impellers and covers must be replaced.

In addition, another cause may be a faulty capacitor. In such cases, the incorrect operation of the device is due to the ingress of water through the cable passage into the cavity of the capacitor compartment.

A faulty capacitor is subjected to mandatory replacement. In the event that when the start button is pressed, the pump does not turn on, first of all, you should make sure that there is voltage in the electrical network.

First of all, the integrity of the cable, which provides power to the unit, is checked. It happens that the control panel of the device fails.

In this case, it is almost impossible to make repairs on your own. Here you will need the help of a qualified specialist.

You should also act if protection is often triggered, which is activated in the event of a breakdown of the power cable and leakage of electricity.

If during start-up the device turns on, but does not pump water, check that the valve is installed correctly.

In this case, the pump must be lifted out of the well and make sure that the valve is installed properly. Sometimes it happens that an air lock forms inside the unit.

To eliminate it, it is necessary to immerse the pump to a greater than usual depth. In this case, the valve is installed at a height exceeding 1 meter.

Another reason for this problem may be correct installation and installation of a check valve. In this case, the pump is also removed and the check valve is reinstalled.

If, when the system is turned on, a partial supply of water is produced and its pressure constantly weakens, then, most likely, the equipment was operated without turning off for quite a long time. The reason for the low pressure is a clogged cleaning filter.

If it is clogged, the filter is disassembled and cleaned. Otherwise, it is completely replaced.

During the intake of water, the pump in some cases gets a large number of sand. In such a situation, the unit is placed in a container with water and it is pumped.

In order to avoid such moments in the future, you need to take care of installing an additional cleaning filter. If the equipment has completely stopped pumping water, then first of all the unit should be de-energized and removed from the well in order to conduct a detailed inspection.

With such a breakdown, the cause may be a significant decrease in the water level in a well or well. It is necessary to immerse the pump to an even greater depth.

In some cases, equipment jamming occurs. Often this is observed with severe contamination of all channels. If it is not possible to eliminate the cause with your own hands, then you should contact a qualified specialist or a service center.

We offer for sale submersible borehole pumps "Vodomet". Before you buy a pump, we suggest that you familiarize yourself with its description and price.

Centrifugal multistage pump The “water cannon” with “floating” impellers, an electric motor “washed” by water and a built-in condenser is designed to supply water from wells with an internal diameter of 100 mm or more, as well as wells and open reservoirs for water supply to the house, watering the garden and vegetable garden. The pump can work in wells with high sand content.

Pumps "Vodomet" can be used: with control "by level" of filling storage capacity, with control “by level” of the pumped out water (automatic pumps with the index “A”) and with a system automatic control"by pressure" (pumps with indices "DOM" and "Ch"). The source of water supply can be a well, a well or an open reservoir.

Selecting a model of a submersible borehole pump Vodomet

Two numbers in its designation will help you choose the right pump model. The first number indicates the maximum flow rate in liters of water per minute at the outlet of the pump in the absence of resistance to water flow. The second number shows the maximum head in meters developed by the pump during dead end operation.

For example: the pump WATER JET 60/52, with a free spout, delivers 60 liters of water per minute (3.6 cubic meters per hour), and when cutting off the supply, i.e. with closed water taps, it develops a pressure of 52 meters (5.2 atm.). In the limit mode, the pump is practically not used. It is most often operated at the so-called "working point", with a nominal (50% of maximum) flow at a nominal (50% of maximum) head. However, you can choose a pump according to the maximum parameters.

VODOJOT pumps with a maximum flow of 60, 115 and 150 liters of water per minute were developed on the basis of many years of analysis of average water consumption and the performance of water sources. VODOJOT pumps with a maximum flow rate of 60 liters of water per minute are designed for water supply sources (well, well, etc.) with a small and medium flow rate and with an expected moderate flow rate (2-3 cubic meters per hour or 35 - 40 l / min, t .e. 3-4 taps) with nominal water flow.

VODOJOT pumps with a maximum flow rate of 115 liters of water per minute are designed for water supply sources (well, well, etc.) with an average and increased flow rate and with an expected increased (3-4 cubic meters per hour or 50 - 65 l / min) nominal water consumption.

Pumps submersible water jet with a maximum flow rate of 150 liters of water per minute are intended for water supply sources (well, open reservoir, etc.) with a high flow rate and with an expected high (4-6 cubic meters per hour or 65 - 100 l / min) nominal water flow.

The maximum pump head should be selected depending on the vertical distance, from the ground surface to the static water level in the source:
- if this distance does not exceed 5 meters, you need a pump with a pressure of 30-32 meters;
- if this distance is up to 25 meters, you need a pump with a pressure of 45-52 meters;
- if this distance is from 25 to 45 meters, you need a pump with a pressure of 60-75 meters;
- if this distance is from 45 to 60 meters, you need a pump with a head of 92-115 meters.

Submersible borehole pumps Water cannon are not equipped with a built-in non-return valve, therefore, in some cases, it is recommended to install check valve at the pump outlet. For example, when a pump is operating in an automatic water supply system for a pressure-controlled pump, a check valve maintains pressure in the system, preventing water from flowing out. Moreover, the check valve should be installed in the pressure line near the pump, since in this case it protects the system from hydraulic shocks, preventing the formation of voids in the pipeline.

A valve installed above 7 meters from the surface of the water in the source cannot prevent the formation of voids in the pipeline, and this leads to water hammer at the moment the pump is turned on. However, the installation of a check valve directly at the outlet of the pump, with a slight deepening of the pump under water, can lead to the formation airlock in the pump and the water will not reach the first impeller, which will lead to "dry running" pump. Therefore, with a slight (up to one meter) deepening of the pump, the check valve should be installed at a distance of 1 to 7 meters from the pump.

In the case of using the pump for filling containers or watering, when periodically removing the pump from the source, the check valve should not be installed, since the hose filled with water is not light in weight. However, care must be taken in this case, otherwise, after turning off the pump, water flows back through the pump and the hose works like a vacuum cleaner. Therefore, a hose dropped to the ground during a backflow can cause the pump to clog.

Water jet pump device

The pump consists of a pump part and a wetted electric motor, located in a single housing made of high quality stainless steel. The components are centered in the housing by means of front and rear covers, as well as an intermediate support. Pump motor oil-filled, sealed, asynchronous with squirrel-cage rotor on rolling bearings. A thermal protector is built into the stator winding to protect the motor from overheating. The motor seal is unloaded, as the pressure inside and outside the motor is equalized by the membrane, the maximum submersion depth of the pump under water is 30 meters. The pump motor is cooled by the pumped water, so the pump must not be allowed to run when there is no flow.

Design feature "floating" pump impellers "Water cannon" is their running-in. It is known that the gap between the rotating and stationary parts of the hydraulic part of the pump is the cause of internal leakage in the pump, which reduces its efficiency. Therefore, ensuring small gaps in a traditional pump is a difficult technological task. During operation, these gaps increase, which, accordingly, reduces the already low efficiency of the pumping stage of a traditional pump.

In the "VODOMET" pump, the impellers are "floating", as they have the ability to move in the axial direction, clinging, under the action of working pressure, to the rear surface of the guide vane (diffuser) of the previous stage. In this case, the contact occurs along one of the two pairs of rubbing surfaces. In the first hours of operation, the plastic shoulder of the impeller in the cover of the guide vane (diffuser) is intensively worn, while electricity consumption increases somewhat and the flow-pressure characteristic decreases. This wear and tear results in "lapping" collar, providing "zero" gap. Then, unloading the first rubbing pair, the second pair of rubbing surfaces comes into contact. This is an anti-friction washer and a ceramic ring. Since the friction of these parts in water occurs without wear, and a "zero" gap has already formed in the zone of the sealing shoulder, the pump reaches the optimal operating mode. This mode is characterized by an increase in the flow-pressure characteristics and a decrease in electricity consumption.

All parts of the pump that come into contact with the pumped water are made of materials approved for contact with foodstuffs. In the rear cover of the pump with the outlet pipe, there are two lugs for fixing the cable. A water-resistant, hygienic cable of the required length exits from the rear cover of the pump, which reduces the risk of incorrect connection of the pump.

Pump with index "BK"- with cable length 1 m. Pump with index "A"(automatic) is equipped with a float switch that prevents the pump from running without water. Such a pump can be used in a well or other source that has enough space to use a float switch. An anti-friction sleeve is installed in the front cover of the pump, which serves as a support for the shaft of the pump part.
In the front cover of the submersible pump, there are suction windows 1.5 x 1.5 mm in size, which prevent the penetration of large particles into the pump.
In the front cover of the pump with an index "M"(main) a fitting is mounted, which allows the pump to be used as a surface pump built into the water supply line.
it is completed with a hydraulic accumulator, a control panel and the necessary shut-off valves that allow you to assemble.
Pump with index "H"(frequency converter) equipped with electronic system automatic control, which provides " smooth start» pump, protection against "dry running"(from the operation of the pump without water consumption) and the exact maintenance of the specified pressure in the water supply system, regardless of the flow rate.

The Russian company "Dzhileks", located in the village of Klimovsk, Moscow Region, produces submersible multistage pumping units. Water cannon pumps are manufactured to provide independent water supply to a private house and garden watering. Moreover, the range of equipment of this brand is represented by a whole set of household appliances that have different power and dimensions. Thanks to such a large selection, the buyer can choose a model that provides the required amount of water.

All submersible pumping units of the Vodomet series are manufactured at domestic enterprises, therefore, even at the development stage, parameters are laid in them that allow the equipment to be adapted to work in the conditions of domestic water supply systems. This is especially important, since our waterways are not as clean as foreign ones.

Downhole pumps of this series are able to pump even dirty water with impurity content up to 300 g per m³. For the production of guides and impellers, the manufacturer uses a special LEXAN polymer. And for the manufacture of thrust bearings, ceramics and graphite are used. Thanks to such innovative additions, the wear resistance of the units increases, their service life increases, and the likelihood of breakdowns is minimized.

At the same time, downhole units of the Dzhileks brand are practically not subject to clogging, since they have a self-cleaning function. It is not surprising that such pumps can only be heard about positive reviews, because in addition to domestic nodes, they use parts of American, French, Swedish, German and Italian production.

The performance and design of pumps of this brand are constantly being improved. For example, new models are distinguished by the fact that the electric motor in them is located above the pumping part. This made it possible to reduce the dimensions of the housing, as well as connect the electrical cable to the upper part of the unit.

Advantages of water jet pumps

Submersible pumps of this brand have whole line advantages over similar models from other manufacturers. Thanks to them, they have earned numerous positive reviews. Among the advantages of these units are the following:

• The borehole and well pump of the Dzhileks brand works very quietly, which is important for country houses and dachas.
• Compact dimensions allow you to choose a unit for any well size.
• Unlike vibration models, submersible pumping units of the Vodomet series do not create turbulences in the water that raise silt and sand from the bottom.
• Acceptable cost, since the pumps are of domestic production.
• High performance and efficiency.
• The units can work even in dirty water containing sand, silt or clay within 2-5 kg/m³.
• Due to the washed motor (water circulates between the stator shell and the unit housing), the electric motor is effectively cooled.
• Another significant advantage is the use of two separate sealing parts in the design. They not only protect the electric motor from high pressure, but also ensure its tightness and separate oil filling of the internal parts.
• In models of the PROF series, the membrane and seal are protected (this function is not provided in other units).

Important to know: pumps must be lowered into the shaft of a hydraulic structure on steel cables. This is the only way to be sure of the reliability of fixation.

Varieties

All pumps of the Vodomet series can be divided into two types:

• well unit;
• borehole pump.

Dzhileks brand well pumps are suitable for use in relatively shallow structures (8-10 m). They can also be used in open reservoirs and various water tanks.

The main condition for the operation of such a unit is sufficient dimensions of the tank, well or reservoir. The thing is that it is necessary to install not only the pumping unit there, but also the float switch.

Many reviews say that the Vodomet well pump differs from the downhole unit in a number of advantages:

• The efficiency of such a device is much higher. Hence, submersible pumps for wells with the same technical characteristics will give greater productivity than similar downhole equipment.
• They are less sensitive to dirty, silty or sandy water than well pumps.
• In such models, it is not necessary to use protection against operation in the absence of water, since there is a simple float switch.
• The price of such units is in the range of $ 90-130, which is lower than the cost pumping equipment for wells.

Models

Submersible pumping units of the Vodomet series are produced in various modifications. All of them are different technical parameters and power. Usually the marking of pumps of this brand looks like this - 55/50A (there may be other combinations of numbers). The letter designation "A" indicates that the pumping equipment is equipped with a float switch that produces automatic shutdown in the absence of water. The numbers in the designation indicate such characteristics:

• The first number is the flow rate of the pumping equipment at the outlet. It is measured in l/min. This value is determined with fully open taps, in conditions where there is no resistance to the movement of water.
• The second number is the maximum head that can be reached with fully screwed taps. Measured in meters.

Based on the marking, we can draw the following conclusions about the operation of units of various modifications:

1. Deep pumps 60/32 with a flow rate of 60 liters per minute will work more efficiently in water intake facilities with a small debit. At the same time, the performance of the hydraulic structure should not be lower than the performance of the pumping equipment. Otherwise, the pump can quickly pump all the water from the water intake and will work "dry". This can lead to failure of the unit.
2. A device marked 60/52 can provide water consumption of 35-40 liters per minute (more than 2 m³ per hour). This is equal to four faucets open at the same time.
3. A Gilex brand pump marked 60/72 with a similar water flow will provide a stronger pressure. Such units allow you to move water over longer distances, so they are suitable if the source is away from home.
4. The 115 liters per minute borehole pump is suitable for use in medium to high production wells. In this case, the debit of a hydraulic structure can be about 4 m³ per hour. Submersible pumping equipment model range 115/115 is one of the most powerful devices. The power of such pumps reaches 2200 kW.
5. For water supply of multi-storey buildings, it is better to use units with a flow rate of 150 l / min. They can only be installed in hydraulic structures with high performance. It is also better to use them when the water flow is more than 4 m³ per hour.

How to choose?

Of course, you can make a choice of a Water Jet pump model based on customer reviews, but it’s still worth doing a simple calculation yourself. To determine the required pressure of pumping equipment, it is necessary to take into account the required pressure in consumer taps. It is important not to forget about possible pressure losses in the pipeline, as well as the height difference between the consumer and the source.

• if this value is less than 5 m, then you can use a pumping unit with a pressure not higher than 35 m. Submersible pumping equipment Vodomet 55/35 is suitable for this purpose;
• if from the water mirror to the earth's surface within 5-25 m, you can buy a pump with a pressure of 40-50 m, for example, a pumping unit Vodomet 60/52;
• at a distance of 25-45 m, it is better to use a model with a pressure indicator in the range of 60-75 m. For these purposes, a submersible device Water cannon 60/72 is suitable;
• if from the water surface to the top of the earth 45-60 m, it is better to choose more powerful units with a pressure of 90 to 150 m. The device of the 115/115 model range will cope well with this task.

Operation and possible breakdowns

Since pumping equipment is completely submerged in water, it works in extreme conditions. Despite constant improvement, the pump can fail. The most common causes of breakdowns can be such phenomena:

• If the installation and use of the unit was carried out without following the recommendations and instructions of the manufacturer, then there is a high probability of a breakdown.
• Voltage fluctuations in the network can lead to the failure of pumping equipment.
• If the unit is constantly pumping very dirty water with a high content of sand particles, this will accelerate its wear and failure.

Important: a guarantee of a long service life deep pump– correct installation in the hydraulic structure. In this case, the diameter of the casing pipe must be at least 100 mm. The unit must be completely submerged in water, but no more than 1.5 m from the bottom of the water intake.

To protect the well from foreign objects, the upper part of the casing string is closed with a special cap. To prevent freezing of water in winter period a caisson is constructed above the upper part of the casing pipe, and the pipeline is connected and laid to the house at a mark located below the freezing point of the soil.

Pumps of the Vodomet series are lowered into the well, suspended on a strong cable, to which a power cable and a hose are attached to the sides for lifting water. The rope is securely fixed at the top.
