They are submersible devices. They are multi-stage units, the operation of which is carried out through the use of centrifugal force.

Among the characteristic design features, which distinguishes the borehole pump Vodomet, can be distinguished:

powerful engine equipped efficient system cooling;
"floating" impellers;
connection of the power cable to the top cover of the product, so that it can be installed in wells with a small cross section casing pipe;
built-in capacitor that allows you to use a three-core cable for connection.

Pump borehole water cannon It has a durable housing made of high quality stainless steel. It is not subject to corrosion, is resistant to mechanical stress and reliably protects internal mechanisms from breakdowns.

The isolation of the hydraulic and electrical parts from the immersion medium is carried out by mechanical seals, which increase the life of the unit.
Oil-filled engine driving deep pumps for the well Vodomet, differs in stability of working parameters.
It is equipped with a protective casing that prevents oil from penetrating the cable.

Depending on the modification, downhole pumps Vodomet can be equipped with:

automatic equipment that prevents the possibility of idling and protects against deformations.
a removable filter, which is installed in the intake part and does not allow sand and dirt to be sucked in.

All components and components in contact with the liquid are made of inert materials. They don't provide negative impact per composition drinking water and do not impair its taste.

Operational Benefits

Downhole pump Jilex Water Cannon is reliable, easy to use and maintain. Its other benefits include:

High efficiency, providing good performance and other technical parameters.
The presence of protection in the form of a thermal protector, which protects the engine from overheating.
Long service life. The pump for the well Water Jet Dzhileks can be used for a long time in intensive mode due to the special arrangement of parts and the use of high-quality raw materials.
small size and weight, simplifying the transportation of the device. In addition, they help to reduce vibrations.

Pumps for water wells Vodomet are characterized by economical energy consumption and almost no noise during operation.
Cooling the motor with pumped water ensures trouble-free performance of the specified functions.
The relay, which protects against overheating, is placed outside the stator windings of the power mechanism. This makes it easier to diagnose breakdowns and carry out repairs.

Due to the use of "floating" impellers, Vodomet well pumps are not very sensitive to the composition of the pumped liquid and can be used to transport water with a high sand content.
Degree of protection IPX8 protects against ingress of moisture and is designed for operation in immersed state for more than 30 minutes.

Suggested range

Pumps for the well Vodomet are represented by several models. They differ in the nuances of design, technical characteristics and equipment.

The line of equipment includes devices that can be used:

for watering;
for sources with low debit;
for the organization of automatic supply.

The numbers in the marking indicate the amount of fluid consumed per minute and the maximum head.

Downhole pump Dzhileks Vodomet PROF - a classic downhole pump, with which it is very easy to organize a water supply system. It will need to purchase a hydraulic accumulator, a pressure switch and other components.

Borehole (well) pump Gilex Water Jet PROF A equipped with a float switch, which prevents operation without water. It turns off and on automatically.

well pump Water cannon "House" represents a more advanced version of the equipment, in terms of technical equipment.
It refers to automatic systems water supply and includes the following elements:

well pump Water jet with a wire for connecting to the electrical network;
storage tank with a durable steel body and a flexible synthetic rubber membrane;
three-pin fitting;
stop valves;
check valve, excluding the flow of fluid in the other direction.

Pressure control in the system is carried out using a control unit, which also allows you to determine the voltage and current in the network.
Using the remote control with a microprocessor, you can program desired parameters in the pipeline, depending on the operating conditions.

The Dom model is a modified water jet pump PROF, which has retained all the best properties of the basic products and is equipped with several additional functions. Among them:

protection against "dry running", voltage surges and overloads;
smooth start, which reduces the likelihood of water hammer during commissioning and reduces loads.

Thanks to the installation of protective systems and the improvement of consumer properties, Dzhileks Vodomet Dom series borehole pumps are more convenient to use.

Application features

In order for the Vodomet downhole pump to retain its functionality for as long as possible, it is necessary to strictly follow the rules of use recommended by the manufacturer. According to them, you should:

apply for pumping medium, the temperature of which is from +1 °C to +35 °C and does not go beyond the specified limit;
avoid installation in sources where the distance to the day is less than 1 m;
exclude the pumping of liquid containing more than 2 kg / m 3 of sand in suspension;
do not allow borehole pumps Vodomet to use if a violation of the integrity of the wire is detected.

To save the power cord for a long time, do not use it to hang the product.

If you are going to use the Dzhileks Vodomet borehole pump for its intended purpose, you must first check the performance. To do this, it is connected to the power supply for a few seconds.

When using the Vodomet pump for wells, it is necessary to provide for the installation of a head that will close the top of the casing and protect it from foreign objects and groundwater.

To prevent freezing, it will be necessary to build a well with a cover, and lay the pipeline below the soil freezing level characteristic of the area.
In this case, the internal cross section of the pressure water supply should not be less than the same parameter of the inlet of the apparatus for water supply.

To hang the water jet borehole pump, you will need a steel cable that is pulled through the lugs in the cover. It must support the weight of the apparatus and the filled pipe.

During the first start-up, the possibility of getting a significant amount of sand should be taken into account. In such a situation, it is forbidden to turn off the unit: it is left to work until the source is “pumped” and there are no impurities.

Mounting example

Borehole pumps Vodomet are manufactured in Klimovsk and are multistage centrifugal pumps designed for autonomous water supply of cottages and dachas.

Borehole pumps Vodomet are structurally somewhat different from most borehole pumps. At "Water cannons" the water intake is not from the side, but from below. This scheme allows you to effectively deal with siltation of wells. Pumps "Vodomet" are modified to work in sandy wells and are designed for long work with sand content up to 150 gr./cu.m. In reality, they can pump several kilograms per cubic meter of water.

Water jet pump. Advantages.

A very competent self-cleaning system of the Vodomet pumps allows them to be used to supply water from wells, where the distance from the pump to the bottom will obviously be small. Such pumps are equipped with a float switch to protect the pump from running without water, and are named with the letter "A".

Borehole pump Water jet can be located at a depth of up to 30 meters from the water surface, which allows them to be recommended for low-budget wells.

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) pressure. However, you can choose a pump according to the maximum parameters.

VODOJOT pumps with a maximum flow rate of 60, 115 and 150 liters of water per minute have been developed on the basis of many years of analysis of average water consumption data 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 a non-return valve on the pump outlet. For example, when a pump is operating in an automatic water supply system for a pressure-controlled pump, a check valve allows the pressure to be maintained in the system, preventing water from escaping. 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 air lock 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 slightly 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 characteristic 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 submersible pump there are suction windows with a size of 1.5 x 1.5 mm, 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 a "soft start" of the 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.

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 casing diameter.

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.

The range of products manufactured by GILEX includes several models of borehole pumps with different technical characteristics. This equipment is intended for use as part of domestic and industrial water supply systems with water intake from wells and boreholes. According to users, well pumps from JILEKS LLC are among the best on the Russian market.
