After drilling a well at personal plot will be completed, and the water in the mine will be completely cleared of sand and clay, you can begin the final stage of arranging an individual water supply system - installation of a well pump. Before installation work you need to choose the right pump, as well as buy the materials and accessories necessary to connect it.

Which pump is suitable for a well?

The choice of pumping equipment begins with determining the type of model. All pumping units are divided into surface and submersible: the former are installed in close proximity to the water source, and the latter must be completely immersed in liquid during operation. Surface models are easy to maintain and their cost is somewhat lower, however, most of these units are designed for a suction depth of 7-9 meters. In addition to conventional surface pumping stations, ejector-type installations are produced that are capable of lifting water from a depth of up to 25-40 meters. Their design requires immersion into the well of not one, but two pipes - suction and pressure.

For deep wells, submersible models are considered a more suitable option. When choosing an electric pump, you need to pay attention to the operating principle of the equipment. It is not recommended to lower vibration devices into the shaft. Installing such a pump in a well will lead to erosion and siltation of the source.

In cases where there is a significant amount of abrasive impurities in the water, you should opt for screw or screw pumps. They are not very productive, but are resistant to sand, clay and lime. If the water contains no more than 0.15% solid particles, it is best to purchase a centrifugal unit. The design of a centrifugal well pump allows the supply of large volumes of liquid to a pressure height of up to 100 meters or more.

Many manufacturers produce models specifically designed for use in deep wells. They are distinguished by smaller body sizes, have protection against engine overheating, and are often additionally equipped with an electric cable and cable, the length of which corresponds to the maximum immersion depth.

Surface pumps are easier to install and cheaper than submersible models, but they are only effective for wells up to 8 meters deep

An important parameter when choosing a model is the diameter of the case. It should be 15-20 mm smaller than the internal dimensions of the casing pipe. Otherwise, the equipment may malfunction and will be damaged for a long time. ahead of schedule declared by the manufacturer. You should also pay attention to the power supply features of the unit. For domestic supply, the power of single-phase installations is quite sufficient.

Additional materials

The list of required materials depends on which borehole pump will be installed. For surface models, you will need a check valve with a filter and a suction hose to immerse into the shaft with a sufficient degree of rigidity. When using an ejector model, you will need to purchase two pipes with a diameter corresponding to the inlet holes of the pump part.

To connect a submersible well pump with your own hands, you will need to purchase the following:

Cable for fixing the pumping unit in the shaft. If the equipment is already equipped with a cable, you should check its length, make sure it is strong and resistant to moisture. The cord must support 5 times the weight of the pump.

Electrical cable. The length of the cable is calculated so that it does not sag, but is not stretched either.

Pipe for connecting to the water supply. Typically, installation of a pump in a well is carried out using plastic pipes with a diameter corresponding to the outlet pipe. When choosing pipes, take into account the distance to the water surface: at a depth of up to 50 m you can purchase plastic designed for a pressure of 10 bar, from 50 to 80 m - up to 12.5 bar, and above 80 you should choose a pipe that can withstand a pressure of 16 bar. The pump can also be connected to the well using metal pipes, but this option is more expensive, and the presence of connections between individual elements increases the likelihood of loss of tightness of the supply pipe and the formation of leaks.

A strong steel assembly on the head of the shaft to secure the pump.

Fastenings for fixing electric cable on the supply pipe.

Installation of surface equipment

Surface models are installed indoors (if the water source is located near the house) or in a pre-prepared insulated well (caisson) near the mouth of the shaft. The installation site must be level; it is recommended that the unit be additionally secured with bolted connections.

Scheme of installing a pump in a well

How to properly connect a surface-type well pump? A check valve with a filter is placed on the lower part of the suction pipe, the upper end is connected to the inlet of the pump part. Ejector models are equipped with a remote block, which is connected to the bottom of the pipes; the upper ends of the suction hoses are attached to the inlet pipes.

The suction pipeline must be completely sealed: when air is sucked into the pipe or at the joints between the blades of the impellers of the pump part, turbulence will be created that will prevent the normal pumping of liquid.

Typically, the connection diagram for a surface pump for a well includes:

  • expansion membrane tank to constantly maintain pressure in the system and mitigate water hammer when starting the engine;
  • an automation unit that starts the engine when the pressure in the water supply drops and turns it off when the pressure rises to the specified parameters;
  • filters for purifying water from impurities.

All of the listed devices can be purchased separately or you can buy an already assembled pumping station, completely ready for connection to the water supply system. Before the first start-up, the pipe and chamber with the impeller are filled with water.

General installation diagram submersible pump and connecting all the necessary elements to the house water supply

Connecting a submersible pump is carried out in several successive stages.

Preliminary work

Before installing the pump in the well, it is necessary to carefully check the entire length of the barrel. In cases where the requirements for drilling a shaft were not met during excavation work, there may be narrowing or curvature at the joints of the casing pipes. If present defects prevent the free passage of the housing of the submersible pumping unit, they must be eliminated.

To fix the unit, you should make a strong steel frame, which is placed on the head of the well. A hole is drilled in it to secure the cable.

Installation stages

Preparation suspension system.

Installation begins with assembly: a check valve is installed on the inlet pipe to prevent the outflow of water from the system when the engine is turned off, then, if necessary, a cup-shaped filter is installed to prevent abrasive impurities from entering the working part of the installation.

The assembled unit is connected to the supply hose using an adapter. To ensure tightness, it is recommended to use winding. The fastening cord is pulled through the eyes provided in the housing and securely fastened. If an electrical cable is not provided in the design, it will also need to be connected to the device. In this case, it is very important to provide reliable protection against moisture penetration: the connection is insulated heat shrink tube, and on top of it - a waterproofing coupling.

The pipe, hose and cable are straightened along their entire length, and then connected together using clamps or clips, making sure that the cable is positioned more freely

Lowering the device into the shaft

After preparing the suspension system, you can proceed to lowering the unit into the well. Perform it slowly and extremely carefully, trying to ensure that the body does not come into contact with the walls of the casing pipe. To protect the device and the walls of the shaft from damage, you can put a protective ring on the housing. You only need to hold on to the fastening cable, while making sure that the hose and electrical cable are not too tight.

There is little space between the walls of the casing and the pump. Therefore, it is better to release the submersible pump into the well very carefully

The depth of immersion depends on the filling of the well and the manufacturer’s recommendations. Before performing work, you must carefully read the instructions. As a rule, the optimal distance to the bottom should be at least 1 m; with a lower location, the likelihood of abrasive particles getting inside the device increases. The recommended distance from the top of the hull to the water surface is at least 50 cm. After reaching pumping unit the recommended depth, the cable is fixed to the frame.

Connecting a well pump

Before connecting the pumping equipment, a trench is dug from the house to the well, the depth of which will be greater than the freezing depth. The supply pipe and electrical cable are laid in the trench. If it is not possible to install communications at the same depth into the house, the exit located above the freezing level should be well insulated.

The connection diagram for a well pump is the same as for surface models: a hydraulic accumulator with an automation unit and filters for water purification are connected to the supply pipe, the cable is connected to a household power supply.

Proper installation of a pump in a well with your own hands will ensure long-term operation of the equipment and uninterrupted supply of water to the water supply system of the house. When replacement or preventative maintenance is required, the pump can be easily lifted to the surface and lowered back into the shaft.

Comfortable living in a private house depends on many factors, and water supply plays an important role here. If there is already a well on the site, then the issue is half resolved. But to ensure a complete water supply, you will need to select a suitable pump, otherwise you will get water from deep and narrow hole It will be, to put it mildly, difficult, don’t you agree?

At first glance, installing a pump in a well seems like a rather difficult task. Here, as in any business, there are a number of important nuances. Therefore, before starting to solve it, it is worth thoroughly studying this issue. We will help you understand the intricacies of installing pumping equipment.

Useful tips for installing surface and submersible pumps are presented in this material. There are also photos and videos with expert advice that will help you better understand the intricacies of installation.

First you need to select and purchase a suitable pump, as well as a number of materials necessary for its successful installation. The pump is usually submersible, but it is highly desirable that it be centrifugal.

Unlike centrifugal models, they cause dangerous vibrations in the well, which can lead to destruction of the soil and casing. Such models are especially dangerous for sand wells, which are less stable than their artesian counterparts.

The pump power must correspond to the productivity of the well. In addition, the immersion depth for which a particular pump is designed should be taken into account. A model designed to operate at a depth of 50 m can supply water from a depth of 60 m, but the pump will soon break down.

A submersible centrifugal pump is the optimal choice for a well. Its performance, size and other indicators should be correlated with the characteristics of your own water source

Another risk factor is the level of quality of drilling work. If an experienced team drilled, the well will better withstand the destructive effects. And for wells created with your own hands or through the efforts of “shabashniks”, it is recommended to use not just a centrifugal pump, but special models for wells.

Such devices better withstand the loads associated with pumping water heavily contaminated with sand, silt, clay particles, etc. Another important point is the diameter of the pump. It must match the dimensions of the casing pipe. It is also important to take into account the power supply features of the pump. For wells, both single-phase and three-phase devices are used.

It is easier to find equipment for four-inch pipes than for three-inch pipes. It would be good if this point was taken into account at the well planning stage. The greater the distance from the pipe walls to the pump housing, the better. If the pump fits into the pipe with difficulty rather than freely, you need to look for a model with a smaller diameter.

Preparation of materials accompanying installation

A stuck pump in a casing can be a major headache. And you need to pull it out (as well as lower it) using a special cable. If the pump is already equipped with a polymer cord, you need to make sure that it is of high quality and of sufficient length. Sometimes it makes more sense to purchase this item separately.

It is believed that a reliable cable or cord must be designed to withstand a load that is at least five times the weight of the equipment attached to it. Of course, it must withstand moisture well, since part of it will constantly be in water.

If the device is suspended relatively shallowly, less than ten meters from the surface, care must be taken to provide additional shock absorption for the equipment during operation. To do this, use a piece of flexible rubber or a medical tourniquet. Metal cable or wire is not suitable for suspension as it does not dampen vibration but may destroy the mount.

A special electrical cable is provided to power the pump. Its length should be sufficient so that the cable lies freely and is not strained.

To supply water from the pump to the house water supply, special plastic pipes. Designs with a diameter of 32 mm or larger are recommended. Otherwise, the water pressure in the system will be insufficient.

To install a submersible pump, a special cable is used, which is designed for long-term operation under water. Its cross-section must correspond technical requirements specified in the product passport

Pipes can be used both metal and plastic. There is controversy regarding the connection of metal pipes. Some experts object to the threaded connection as less reliable. It is recommended to use flanges, and the bolt should be on top, this will prevent it from accidentally falling into the well.

But threaded connections in wells are used quite successfully. During installation, winding must be used. Some experts recommend using linen or “Tangit” sealing tape instead of the usual FUM tape or tow. The linen winding is additionally strengthened with silicone sealant or similar material.

The characteristics of the water supply pipe should be selected in accordance with its operating conditions. For depths up to 50 meters, HDPE pipes designed for a pressure of 10 atm are used. For a depth of 50-80 m, you will need pipes capable of operating under a pressure of 12.5 atm., and for more deep wells 16 atm pipes are used.

In addition to the pump, pipes and cord or cable, before installing, it is recommended to stock up on the following materials:

  • clamps for securing the electrical cable to the pipe;
  • check valve;
  • pressure gauge;
  • shut-off valve for the water pipe;
  • steel fastening unit;
  • power cable, etc.

Before connecting the pipe to the pump, attach a nipple adapter to its outlet. Usually modern submersible pumps are equipped with such a device, but if it is not there, this unit must be purchased separately.

It should be remembered that to pump the well immediately after drilling, i.e. To remove large amounts of very dirty water from a well, such a pump cannot be used. It will quickly fail. Usually the well is pumped with a separate pump, which is cheaper and works better when working with dirty water.

Rules for installing the surface version

Surface pumps are not often used for this type of water supply as they are only suitable for shallow hydraulic structures, up to eight meters deep.

And yet, this option has a right to exist, and its installation is no more complicated than installing submersible equipment.

Surface pumps are easier to install and cheaper than submersible models, but they are only effective for wells up to eight meters deep

Mount the device as follows:

  1. The surface pump is installed in a special caisson or a separate room.
  2. A hose of suitable length is connected to the suction pipe of the pump.
  3. A check valve is attached to the other end of the hose (a protective measure to prevent water from draining when the pump stops running).
  4. A protective guard is installed on the valve. strainer, preventing the penetration of various contaminants into the pump housing.
  5. The hose is lowered into the well.

At this point, the installation can be considered complete and a test run of the pump can be done. To install such a pump in a well, a special adapter is often used. In this case, the hose is connected to the adapter, and the adapter is connected to the pump. The rest of the installation procedure is exactly the same.

It is a little more difficult to install a surface pump equipped with a remote ejector into a well. In this case, two hoses need to be lowered into the well. In addition to the suction hose, a pressure hose is also installed. It is connected to the side fitting of the ejector using a special outlet.

After the drilling work is completed, proper installation is required deep well pump into the well. This will ensure its uninterrupted and long-term operation. The owner of the site can cope with this procedure independently if he has a standard set of tools and the necessary materials.

Equipment selection

For the drilled hole, you need to select a pump that will meet all operational requirements. You need to choose accordingly from submersible models, since surface devices are capable of operating at shallow depths, less than 8-10 meters.

Vibrating

Popular a budget option pump, which well owners love for its ease of maintenance and affordable cost. There are no bulky bearings or constantly rotating elements, which reduces wear, reduces heat and extends the interval of continuous operation during one start. Vibration pump models are easy to assemble and install in a well.

At the same time, they are very economical, weigh little due to the operating principle of oscillation, and not the operation of complex mechanical components that require lubrication. When used correctly, they last a very long time, but have a number of features. For example, vibrating equipment can only be used in a fixed well, otherwise the soil will begin to crumble and close the well. The recommended immersion depth is up to 3 meters, which also entails a number of restrictions.

Centrifugal

This type of equipment is designed to work at greater depths than its vibrating counterpart. However, centrifugal pumps have a higher cost. With their help it is possible to pump both cold water, and hot or some solutions of chemically active liquids.

Among the disadvantages, it should be noted the low pressure, not exceeding 45-40 meters. There is no function for self-suction of liquid - before putting the unit into operation, it is necessary to fill in the liquid. And most importantly, its power relative to vibration is weak.

Installation rules

  • Installing a deep-well pump in a well, the video of which is presented on the page, begins with checking the correct installation of the casing pipe.

It should have the most vertical state, which is controlled by the construction plumb line. Excessive misalignment may affect the proper operation of the pump.

  • We also check the ease of passage through the casing. The most acceptable gap between the pump wall and the pipe is at least 5-7 millimeters on each side.
  • Too small a distance will lead to rapid wear of the housing. This is especially true for vibration models. Their operating principle provides for the possibility of a small stroke inside the working hole.

Carrying out the procedure

The pump can be suspended on a nylon cord or multi-strand cable with a diameter of 5 mm or more. For the cord, select a breaking force that will be 5-10 times greater than the mass of the pump. Information about this parameter is on the packaging. The end of the rope should be trimmed minimally and then lightly burned with matches or a lighter to prevent the rope from unraveling.

When diving to the horizon below 10-15 meters, it is customary to form a damping unit. It is made from high-quality rubber or medium-hard springs. During operation, the pump will vibrate, and this solution will reduce the amplitude of vibration.

Be sure to use a suspension that is strong enough to support 10 times the weight of the drainage pump. It is best to make the attachment point at a distance of at least 10cm from the inlet holes.

To ensure rigidity, the bundle of cable, pipe (flexible hose) and cord is fixed with electrical tape.

We tightly wrap a couple of circles in the form of a ring every 1.3-1.5 m in length from the pump until the entire bundle exits the drill hole. The first ring should be made from the pump at a distance of no further than half a meter.

When connecting, it is not advisable to use threaded connections. They will turn out to be poorly effective due to the effects of corrosion, because there is an aggressive, humid environment around the pipe.

As a last resort, a flange connection is used. At the same time, there is a subtlety when the bolt must extend towards the bottom, so when dismantling the structure it will be easier to stick out the assembled pipes with the pump.

Before connecting the additional hydraulic accumulator to the pumping station, we place the upper side of the discharge pipeline on the base plate. At the next stage, we install a check valve and, if necessary, install a valve. A device can be installed into the design to measure the current pressure in the system.

We attach the prepared suspension to the transverse beam. At the final stage, we lower the pump into the well. During the process, it is advisable to avoid rubbing the body against the walls, doing everything strictly vertically.

It is advisable to leave space for measuring stationary water levels. To do this, a gas collection pipe is installed in one of the holes in the support platform. It must be lowered below the dynamic water level.

Using a megger, we determine the level of current winding resistance on the electric motor with the cable lowered. Now you can connect the control station to the pump.

Allowable depth

The owner of a well can determine the value of the stationary water level using its passport. It is physically measured from the soil horizontal to the liquid horizontal when the equipment is not working. When the pump is started, the water flows out more low level. You can also measure it or find out from your passport. This value refers to the dynamic water level.

Scheme correct location equipment relative to the level of the house and well

It will be possible to ensure proper cooling of the pump and its built-in electric motor by hanging the submerged pump on the horizon at least 0.3-0.4 m below the dynamic level. A more correct position would be 2-3 meters below the dynamic level.

At the same time, vibration or centrifugal pumps should not be allowed to operate at the very bottom. You will need to hang the device, 1...2 meters away from the lowest point. This will ensure there is clean water in the system.

Emergency pump replacement

The need for replacement does not arise very often. However, breakdowns occur or the device reaches its full service life. Then it must be replaced with a new one. There are reasons for accidents due to negligence or improper operation. If the power is insufficient, it is also possible to replace the pump with a more productive device.

You can replace the pump yourself or with the help of specialists. The second option is preferable for beginners. Especially if it was installed before you, and there is no information about the depth of the well or the hydraulic equipment has a significant mass.

Most connections will need to be cut and clamps will need to be replaced with new ones after significant corrosion has occurred. Having disconnected the pipes, we check the functionality of the device in any container. If necessary, we change it to a more powerful one or to a working one.

Owners of private households prefer tap water, which most often has very poor taste, to clean water obtained from a deep well.

This requires special equipment, as well as the help of specialist drillers. After all, it is impossible to dig a well by hand, especially if you are interested in drinking water and not industrial water.

But the arrangement of the future source of life-giving moisture does not end there. Having done everything preparatory work, including such as the installation and installation of a pump in a well, proceed to the main stage of testing the performance of the equipment and analyzing the resulting water.

But in order for the result to meet your expectations, it is necessary to complete all stages of equipment installation with the utmost precision.

What is a well pump?

This is equipment used for pumping water. Its main feature is the need to immerse the unit in water during operation. At the same time, it can lift water to the surface from a depth of up to 400 meters. The design of borehole pumps is quite complex; high-tech engineering solutions are used in their creation.

Types of pumps

There are several types of this equipment:

  • Deep;
  • For wells;
  • Borehole.

The former have a high cost due to their complex design. Pumps for wells are used for reservoirs with shallow depths, so they are simpler in technical terms and, accordingly, have a lower cost.

Downhole models are submersible pumps. They are installed in boreholes and mine wells and are used to pump water from various depths.

The price for installing such a pump in a well is quite high. This must be taken into account when choosing. Structurally, they consist of a multistage centrifugal pump and an electric motor with a rigid shaft connection, also of a submersible type.

Watch the video, types of pumps:

Such equipment has a cylindrical shape and small dimensions, which makes it possible to use them even in narrow wells. They are able to provide the necessary water pressure from the most remote sources. There are two types:

  • Centrifugal;
  • Vortex.

The first ones have a design of a large number of stages, which allows them to be used for supplying water containing mechanical impurities. While vortex ones are designed exclusively for pure liquid without any additives.

A model is usually selected taking into account the depth of the well, the maximum demand and the required pressure.

Which pump to choose

In order to pump drinking water from a well, one of two types of equipment is usually used: deep or surface. The first one must be completely immersed in water, so installation is carried out according to a certain pattern. The second one is usually located on the ground.

It pumps water by sucking it from the source, but the deeper the vein is, the more powerful the equipment must be. Therefore, surface equipment is usually used for wells and boreholes up to 8 meters deep. But at the same time, such a pump is very easy to install.

Watch the video, expert advice:

Submersible models are installed directly into the pipe, and they must be completely immersed in water. Their operating principle is based on pushing liquid into pipes. They are selected taking into account the height to which the equipment will have to push water. Its installation is much more complicated, and choosing the necessary modification is not very easy. However, most wells are deep, so submersible ones are most often used.

Preparation for installation of water supply equipment

The installation process of a deep-well pump depends on many factors:

  1. Required pressure;
  2. Pressure;
  3. Reliability;
  4. Ease of use.

But before proceeding with installation, it is necessary to determine how well the parameters of the equipment correspond to the dimensions of the well and select an installation scheme for the well pump. In addition, the characteristics of the device are determined, the power of which must correspond to the required pressure and volume of water consumed.

To install, you must purchase in advance:

  • Pump;
  • Stainless steel clamps;
  • Pipes;
  • Fitting.

The pipes and cable must correspond to the length of the dive plus 2-3 m in reserve. In order for the well to be in constant operation, a 220 V stabilizer is required.

Installation steps

Pipe fastening

Installation begins with disassembling the head. Its flange together with the sealing ring are put on the casing pipe. Then measure the length of the cable and make two loops at its end. One of them is passed into the eye of the pump, and the second through the carabiner of the head.

The pump is installed in the well by holding it by the cable. It is necessary to ensure that the pipe with cable and cable does not twist. In this case, the latter are attached with special ties so that there is no sagging. After the immersion is completed to the required depth, the end of the pipe is cut at a short distance from the head flange.

Watch the video, installation:

Installing a well pump is quite simple and you can handle it yourself. However, some nuances must be taken into account:

  • Before carrying out installation work, the well must be cleaned;
  • Water is pumped until the sediment in the form of sand disappears.

There is one more thing important condition. The pump must be placed in the well in such a way that it does not reach the bottom by 1 m, but is completely submerged in water. This installation guarantees normal operation of the equipment.

Causes of failure and troubleshooting methods

If your pump begins to vibrate during operation or the tone of the noise it produces has changed, or pressure pulsations have appeared, then you need to contact a specialist. Perhaps it has malfunctioned. There can be many reasons for this; they are divided into several groups:

  • Mechanical;
  • Control systems;
  • Hydraulics.

And although manufacturing defects are usually identified during the preparation and test run, this is not all. Some of them may appear after some time of use.

Example installation and diagram of a borehole pump:

In addition, during pump operation, certain parts wear out, such as bearings, sealing elements and rubber coupling parts. They lead to the changes described above.

Some of them can be fixed on your own. For example, if the housing is depressurized, disconnect the power supply and remove the electric motor from the housing. Next, take out the magnet and cut small grooves across its entire surface. It is then coated with sealant and placed back into the housing using a press. After drying, the pump is assembled and placed back into the well.

But since malfunctions can be very different and not all of them can be fixed at home, it is better to entrust this process to professionals.

One of the primary tasks of every owner of a suburban area is to provide living space drinking water. Several decades ago, this problem was solved by digging a well.

Deep-well pumps are easy to install, you don’t need to look after them, since they are protected against “dry running,” and the price is quite reasonable.

These days, the best source of drinking water is your own well. Correct installation of pumping equipment is the key to the effective functioning of the water supply system at home.

Preparatory work

To drinking water arrived uninterruptedly Vacation home, you need to purchase a pump that is characterized by reliable operation and excellent quality. One of these types of equipment are deep-well pumps.

Before lowering equipment into a well, its exact depth and width should be determined. The choice of pump model directly depends on the depth of the well. On the one hand, the unit should not lift water in an amount that exceeds the productivity (dynamic potential) of the well. On the other hand, the pressure should be enough for normal water supply to the house and land.

Electrical wiring is installed immediately. Even if you plan to use the pump irregularly. An extension cord is not suitable since the equipment consumes a large amount of electrical energy. This often leads to overheating of the cable and melting of the plug, which can cause a short circuit and a fire.

When installing the pump, ensure the presence of optimal voltage electrical network, on which the indicators of water pressure and equipment pressure depend. Depending on the power of the unit, the need for two or three phases of electric current is determined.

The deep-well pump is quite sensitive to voltage changes. Therefore, when connecting it to the electrical network, it is better to use a voltage stabilizer (220 V). If electrical wire needs to be increased, then the soldering method is used, followed by insulating the cable into a fluid coupling. It is recommended to connect cables that have insulation of the same color.

The well needs to be cleaned. To do this, a small amount of water is pumped out. Pumping is carried out until the impurities of soil and sand disappear. Only after this can installation work be carried out.

To efficiently install a pump in a well, we will need the following materials and tools:

  • safety rope;
  • HDPE pipe;
  • hose;
  • fitting;
  • couplings;
  • insulating tape;
  • silicone sealant;
  • clamps;
  • head kit;
  • pipe wrench;
  • metal scissors;
  • bending pliers;
  • hammer;
  • air gun;
  • hexagon;
  • roulette;
  • square;
  • lace.

The safety rope and pipe are purchased with a margin of 2-3 m.

Nuances of equipment installation

On initial stage The casing should be checked carefully. There should be no narrowing, unevenness or curvature of the structure. The presence of any defects will lead to difficulty correct installation deep-well pump and its premature deterioration.

It is immediately worth noting that there should be no significant discrepancies between the diameter of the HDPE pipe and the diameter of the pump. A large difference in size may negatively affect the efficient operation of the unit. In some cases, this can result in equipment failure. The maximum rate of discrepancy can be found in the instructions that come with the pump.

Installation of equipment is carried out on a clean and level surface. A fitting is screwed to the pump, which has different external threads on both sides. The fitting is connected to the HDPE coupling. For maximum thread tightness, flax is used, which is coated with silicone sealant.

The HDPE pipe is unwound. It should be laid in as straight a line as possible. It's best to take advantage polyethylene pipe, which has a diameter of 32 mm. If its diameter is less than 32 mm, pressure loss will increase and water pressure will deteriorate.

The end of the pipe that connects to the deep-well pump is pulled out and straightened. The equipment must fit smoothly into the well. To install the pipe to the pump, use a HDPE coupling, which is tightened with a pipe wrench.

A safety rope and an electrical wire are unwound along the pipe. The cable is threaded through special eyelets-brackets. Two loops are made. The two ends of the cable are compressed with steel clamps.

Electrical tape is used to secure the electrical cable and cable to the pipe. There is no need to strongly attract them to the pipe. If the cable and cable are not secured to the pipe, then when lifting the pump from a depth they may become tangled.

The next step is installing the head. To facilitate this process, all connecting screws are unscrewed. The head flange is placed on the pipe. The extreme part of the pipe is lubricated with sealant. Water pipe connects to the rubber ring of the head. The casing pipe is cut before the head is installed. The pipe should protrude 25-30 cm above the well.

Completion of installation work

The pump is lowered into the well. If in some area the equipment does not pass further, it is necessary to carefully rotate the pump or pipe around its axis. If the unit does not lower further, it should be pulled to the surface and try to better align the pipe. The pump must be installed below the water level and above 1 m from the bottom of the well.

It takes two people to complete the installation of the pump. One person is holding the pipe. His assistant must thread the cable through the head and secure it to the carabiner. The upper part of the head with a cable and pipe is lowered into the well. Both parts of the head are combined.

To check the correct location of the pump (it should be fixed with a cable and not hanging on the pipe), press on the end of the pipe.

It should go down a little. Now the head can be tightened with screws. After installing the equipment, all performance indicators are checked: pressure, power and amount of electricity consumed.

Largely from correct installation deep-well pumps will depend on the quality of operation and service life of the equipment. The use of low quality materials and violation of the pump installation technology in the well can cause breakage or premature failure of the equipment. And this is fraught with additional costs for creating a new well, since it is almost impossible to get a stuck pump.
