Pumping equipment intended for installation in a well acts as an important element responsible for water intake. The functioning of the entire water supply system will depend on how correctly the equipment was selected and installed. Before starting installation of the pump, it is necessary to analyze the well for the absence of curvatures or any kind of narrowing that it may have. If such conditions occur, then you must be prepared for the fact that installation will occur with some difficulties. It must be remembered that the service life of the equipment will be significantly reduced. If the difference between the pipe diameters turns out to be quite impressive, then the device will not be able to cool properly. This will cause the pump to catch fire. Experts emphasize that too small a difference can lead to problems that arise during the operation of the equipment. If you are interested in this issue, then you can find out about the minimum acceptable indicators by looking at the technical documentation.
Installing a pump in a well
It should be drilled into the well only after the foreman or team has selected a cord that meets certain requirements. The rope must withstand a breaking load that is five times the weight of the device itself. Among other things, you need to pay attention to what distance must be maintained to fix the suspension. It is imperative to exclude suction of the node. To do this, it should be located no closer than 10 m from the inlet. If installing a pump in a well is accompanied by lowering the device to a more impressive depth, then a spring suspension is fixed at the end of the cable. This component will help dampen vibrations. This element can be a medical tourniquet.
Technological features of the installation
Installing a pump in a well should not involve the use of a steel cable, which some craftsmen use as a suspension. This rule should not be neglected for the reason that a metal element can break the fasteners located on the pump body. Maintaining a step ranging from 0.7 to 1.3 meters, it is necessary to strengthen the electrical cord, the nylon suspension, and the pipe (the latter must be made of metal-plastic). To carry out these manipulations, you should use electrical tape. Stepping back about 20 cm from the pipe, you need to make one fastening.
How to avoid mistakes
Installation of a pump in a well should not involve the use of threaded connections to connect the device. Experts say that they may be susceptible to corrosion during operation. That is why it is recommended to use an alternative solution that involves using the mounting bolt must be facing upward, while the nut will be facing down. This way you will be able to prevent the bolt from falling into the well, which can happen completely by accident. If this cannot be avoided, the well will be stopped.
When installing a submersible pump in a well, the upper part, which belongs to the discharge pipeline, must be well fixed to the base plate. Then you can begin installation work involving the use of a check valve. It is worth considering that this recommendation is true for all variations that lack this component. The suspension needs to be strengthened to the crossbar. It is important to prevent any contact of the surface of the pump housing with the walls of the well. If you are not sure that you can perform these manipulations without interaction of materials, then you can play it safe by protecting the case using a rubber ring. The insulation resistance of the motor winding is determined by a pressure gauge. The next step will be to check whether the device is at a sufficient depth. You can then test how well the electric motor functions when a load is placed on it.
About the diving depth
If you decide to install a water pump in a well yourself, then you need to think about the depth of its location. The equipment is installed 30 cm below the so-called dynamic water level. This figure is minimal. Under the static level, the distance from the water surface to the surface of the earth should be raised. After pumping water from the water intake, you should measure the level at which the stop will be made. This position will become the dynamic level. The step from the pump to the bottom should be equal to the limit of 1 to 2 meters. This figure may be increased. If you are installing a submersible pump in a well for the first time, then when choosing equipment you need to pay attention to those models that have a float switch. If the water level in the well reaches the most critical level, the float switch will perform its function by stopping the engine.
Reinstallation of the pump in the well
Do-it-yourself pump installation in a well can be done again. This need arises in some cases. Among them are equipment falling into a water intake. The most common cause is a broken fastening cable. It may be necessary to replace the installation if the equipment modification is selected incorrectly. Quite often, purchased pumps have insufficient or, on the contrary, excessive power. This also applies to performance. Re-installation into the well may also be necessary if the operation or installation was carried out in violation of the rules and technology. Well owners are faced with the problem of voltage drop that occurs in the electrical network. This may also contribute to the need to change equipment. Re-installation of the water pump in the well is also carried out by pulling out the electrical cable, as well as wedging the equipment. If a break in the water-lifting pipe, sagging cables, or groundwater fluctuations have occurred, the equipment must be immediately removed and replaced.
Replacing the pump with a new one
You can carry out the replacement work yourself or use the services of specialists. If you decide to carry out the work yourself, you will need the help of several more people. One master will not be able to cope with the weight of 100 kilograms, which is possessed by equipment located at a depth of 50 meters. You will also need a safety rope for manipulation. After removing the equipment, it should be checked for maintainability. If there is no chance of returning the pump to operation, then you need to purchase and install a new unit.
Work procedure
Step-by-step installation of a pump in a well involves initially disconnecting the equipment from the power supply. In the place where the pipe was connected, the fastening must be unscrewed. The old pump is removed quite slowly, and it is necessary to provide insurance with a cable. It is necessary to pull out the equipment continuously, with the help of three people. After removing the pump, you can begin installing a new one. Downhole installation involves fixing the device to the pipe. It is necessary to connect a cable to the base, as well as solder the wires and install a fluid coupling. The wires are secured to the pipe. The next step is to lower the device into the well. The electrical cable must be protected from rubbing at the edge.
Final works
Once the pump has reached the required depth, it should be tested by connecting it to the electrical network. If the need arises, it will be necessary to reconfigure the automation. Installation of a deep-well pump in a well can be done independently, but experts recommend seeking professional help. Among other things, this approach is more acceptable for the reason that a team of professionals guarantees a successful outcome.
In order to provide a country house or cottage with the required amount of water used for domestic needs and for watering green spaces on a personal plot, a source of water supply is needed, which can be a well or a borehole. If it is best to entrust the solution to issues with the arrangement of such a source to qualified and experienced specialists, then installing a pump in a well that will pump water out of it can easily be done independently.
How to properly install a pump in an already prepared well? First of all, you need to purchase a device whose technical characteristics correspond to the parameters of the autonomous water supply system being installed. Only if the pump is selected correctly, and the pump is installed in the well properly, can you count on the efficient and uninterrupted operation of such a device over a long period.
How to install a pump in a well and perform commissioning work
After drilling a well, a casing pipe is installed into it, into which a deep-well pump is lowered. Before installing a deep-well pump into a well, you should make sure that there are no narrowings or curvatures along the entire inner surface of the casing pipe, which can not only complicate installation, but also significantly reduce the life of the pumping equipment.
Before installing a submersible pump in a well, the difference between the inner diameter of the casing pipe and the outer diameter of the hydraulic machine body should be determined. If such a difference is too small, then all the defects present on the inner walls of the casing pipe will negatively affect the operation of the device. If the gap between the pump body and the pipe walls is too large, this may cause equipment failure. The water that the deep-well pump pumps out of the well must move at a sufficient speed to ensure effective cooling of the pump, therefore, when installing, the gap between its body and the inner walls of the casing must be optimal. This value is usually indicated in the technical data sheet for each submersible pump model.
Installation of a submersible pump in a well is carried out using a polyamide cord, which is tied to the body of the hydraulic machine. When choosing such a cord for installing a pump in a well with your own hands, you should keep in mind that this product must withstand a tensile load, the value of which is at least five times the weight of the pumping equipment being installed. To eliminate the risk of the knot with which the polyamide cord is attached to its body being sucked into the inside of the hydraulic machine, such a knot should be tied at a distance of about 10 cm from the inlet holes of the device, and the ends of the cord should be melted.
If the depth of the well into which the deep-well pump is mounted does not exceed 10 meters, then in addition to the polyamide cord, when installing the pump, it is necessary to use a spring suspension attached to the body of the device. As such a suspension, which is necessary in order to dampen vibrations of a working submersible pump, you can use a medical tourniquet or tape made of flexible rubber. However, wire or cable made of metal cannot be used for this function. This is explained by the fact that the elements of such a suspension, which are characterized by high hardness, can simply break the mounting holes on the pump body.
Installation of a deep-well pump assumes that, together with the hydraulic machine itself, which is installed in the well using a polyamide cord, a power cord and a metal-plastic pipe connected to the discharge pipe are lowered into the casing pipe. All three elements lowered into the well together with the pump (polyamide cord, power cord and pipe) are fastened together using insulating tape, and the step with which such fastenings are made can be in the range of 70–130 cm. Place the first ligament connecting polyamide cord, pump power supply wire and pipe should be at a distance of at least 20–30 cm from the discharge pipe.
Since threaded connections reduce the strength of pipes, they try to install a well pump without using them. As a rule, installation of a submersible pump in a well is carried out using flange-type connections, which are highly reliable and durable. The fastening bolts in connections of this type are inserted through the upper flange, and the nut is screwed onto it from below. The need to follow such a recommendation is explained by the fact that if an unscrewed bolt falls into the well shaft, it will cause much more damage to it than a nut falling into it.
Before installing a well pump, you should first measure the depth of the water in the underground source. To carry out this measurement, a column of gas pipes is used, lowered into the well shaft through a hole in the base plate.
You should also know how to lower the pump into the well so as not to damage the device housing during installation. When lowering the pump into the well, it is best to put a rubber ring on its body, which will protect it from damage when hitting the walls of the casing pipe. After the submersible pump is lowered into the well to the required depth, the upper end of the suspension on which such a device is supported is tied to a special crossbar fixed to the surface of the earth.
When equipping an underground water source with pumping equipment, it is important to know how to install a pump in a well, as well as how to properly connect such a device to the pipeline system that it will serve. Installation of a well pump, carried out after the equipment is already at the required depth of the underground water source, is carried out according to the following algorithm.
- The upper end of the pipe connected to the pump discharge pipe is attached to the base plate with which the well is equipped.
- If the pump design does not provide a built-in check valve, it must be purchased separately for installation on the discharge line.
- In addition, it is necessary to install a valve, a discharge elbow and a pressure gauge on the discharge pipe, with which the liquid pressure will be measured.
- After all of the above steps have been completed, you can connect the elbow extending from the injection pipe to the pipeline itself, through which the water pumped from the well will flow to the points of its consumption.
Before connecting a pump placed in a well to a power supply and control station for such a device, it is advisable to measure the winding resistance of its drive motor and the electrical cable immersed in a liquid medium. You can perform this procedure to complete the installation of a well pump yourself using a megohmmeter. After checking, the pump's electrical cable is connected to the control station. Then a test run of the installed equipment is performed.
How to Determine the Required Source Depth
The borehole pump must be installed at a certain depth of the water source. When using a well as a source of water supply, the static and dynamic levels of the location of the pumped liquid medium in it are taken into account. The static level is understood as the distance at which the surface of water, in a calm state, is located from the surface of the earth. At the dynamic level, water is in the well after it begins to be pumped out.
In order for submersible pumping equipment to function effectively and be cooled efficiently by the liquid medium it pumps, it should be located in the well at a level at least 30 cm below the dynamic level. If the thickness of the water layer allows, then it will be better if the deep pump is installed at a level located 2–3 m below the dynamic level. It should be taken into account that the pump installed in the well should be located at a distance of at least 1–2 m from its bottom.
Dismantling the deep-well pump
The need for dismantling due to pump failure may arise for a number of reasons, the most common of which are:
- incorrect installation of a submersible pump in a well;
- incorrectly selected elements of automatic control of pumping equipment;
- incorrect choice of the hydraulic machine itself based on its power.
So, if a pump, initially designed to service wells with a depth of no more than 50 m, is used to lift water to a height of about 80 m, then repairs to such equipment may be required after just a few months of its operation. The automation of this pump, configured for a certain pressure of the pumped liquid medium, simply will not periodically turn off the device, as a result of which it will work with constant overloads and, accordingly, will quickly fail.
It is now impossible to do without well pumps in most suburban areas. After all, it is wells in modern society of summer residents or residents of country houses that provide approximately 85% of the liquid.
1.1 Installation features depending on the type of pump
So, pumps that are created for ordinary household water supply are most often divided into (that is, internal) and surface. Directly submersible type pumps most often include well and borehole equipment. Interestingly, they are completely immersed in water during operation.
Their main function is to lift the required water from great depths. As for surface pumps, they are used to extract water from a relatively shallow depth (maximum depth is eight meters). They are installed only separately from the main source of water supply.
Many may try to do this, but if a centrifugal type device is required, difficulties may arise. Borehole pumps (in this case we are talking about their horizontal arrangement) are often used to draw water from various rivers or any other open types of reservoirs.
This option is perfect for people who do not have the opportunity to drill a well and whose water source is located far from home. In this case, you need to select a mechanism with high power ratings.
It is worth noting that well pumps have a number of quite significant advantages and advantages:
- Long service life;
- Very low noise level;
- Complete absence of rubbing parts;
- Ease of connection (even if you wanted to do it yourself);
- Significant depth of water intake, which is unacceptable for many other types and types of pumps.
If you decide to install a well pump yourself, then it is worth remembering that this process will require certain knowledge in this area.
The main thing is to install the centrifugal submersible pump carefully and competently, because all future use will depend solely on the correct arrangement of the equipment purchased or made by yourself.
Remember that an error during the installation of a pump, including a centrifugal or deep-well type, a violation of technology, as well as the use of cheap materials can lead to various negative consequences in the future. These include:
- Inability to lift the pump unit during dismantling;
- Premature failure;
- Breakage of communications of the pumping mechanism.
All this can lead to the impossibility of further connecting it, so a diagram can help here, which can tell you in detail how to do everything correctly.
If your well pump simply gets stuck, then its further use will be under serious threat, after which all organizational work on the construction and actual drilling of the well will have to start all over again.
2 Nuances and stages of installation of a well pump
So, after a careful and painstaking selection and purchase of the necessary devices, the subsequent installation of a well pump belongs to the second, very important stage of completing the well.
It is worth remembering that the pumping unit must be placed in the well you created below the water mark. But here it is important to measure one meter to the bottom so that during operation of your equipment there is no capture of soil and sand that has settled at the bottom. After a certain time, they can accumulate in large volumes in the well, or rather at its bottom.
For this reason, the immersion depth is extremely important, even when using a centrifugal or submersible pump. However, in most cases, the immersion depth is automatically adjusted by special automatic floats. In the event of a critical drop in the water level from the source, the float will immediately turn off the device.
For subsequent connection, a special plastic tube or hose is also carefully lowered into the well along with the pump. It is along it that the water subsequently rises. Next, the scheme is simple - an electric cable for the electric motor is secured and, of course, a safety rope, which is placed on the head of the created well.
The water supply pipe and the protected one must be connected or brought into the house. To further seal the mouth of the created structure, a cap is used.
It is important to know that during the installation of water equipment it is worth ensuring in advance the organization of the so-called check valve. It is he who will perform the function of protecting the system from dangerous water hammer.
If you need to ensure the autonomy of the entire system, the power supply cables can be connected to a hydraulic accumulator, which will generate the required energy.
The water supply from the caisson to the house must be laid in the ground in advance. The most important thing here is that it is below the freezing level, that is, at a depth of no less than 1.5 meters.
Before installing submersible pumping equipment, you should carefully clean the new well, pump out all the water, and carry out good preparation. If you are sure that the well is completely cleared of various excess particles, including sand, you can begin connecting.
The further scheme does not require special knowledge - the pump is lowered into the well, a special start-up protection mechanism is installed, and then the necessary regulatory processes begin.
The main problem that arises for a person who has become the owner of a suburban area is providing water for his family and all its household needs, including watering the garden. The key requirement for a source of autonomous water supply is, first of all, the quality of life-giving moisture. Water should not contain harmful impurities. It is not always possible to achieve this by drawing water from a traditional well. Wells are more sensitive to contamination and require regular maintenance and cleaning.
Deep wells are much more practical to operate. Drilling such a well will provide owners with a productive source of water supply with healthy and tasty water. And in order to supply water from a well to the home water supply, you need to install a sufficiently powerful pump. And you can do it yourself.
Varieties
Pumps designed for use in wells can operate at great depths. Most models are submerged in water - they are more often called deep-well pumping equipment. Units of this type have compact dimensions with a small diameter and a long service life. They can fit even in a narrow needle-type well (Abyssinian well). But there are also surface models that are successfully used for pumping water from medium-depth wells. All this must be taken into account if you want to know.
The classification is as follows:
Submersible (deep models):
- vibration;
- centrifugal.
Surface:
- self-priming type;
- manual columns, more often used in Abyssinian wells.
Submersible vibration type models
These are the most economical units to date. They cost little and are absolutely easy to maintain. The principle of their operation is to create a magnetic field by an electric coil, which attracts the armature of the pumping chamber and thereby creates the vibration necessary for operation.
Advantages:
- low cost;
- simplicity of design and operation;
- the absence of rotating elements in the housing, which most often fail in other pumps;
- high-quality engine cooling due to water circulation;
- low electrical energy consumption.
Flaws:
- short power cable length for some models;
- engine noise;
- It is undesirable to use the unit at great depths - the optimal value is 10-15 meters, although
- the device is also used in deeper sources;
- Works only with slightly contaminated water (up to 2 mm).
Especially popular in Russia.
The main purpose of vibration-type submersible pumps is pumping liquid from containers, watering beds, pumping drainage water from flooded basements, and providing water to autonomous water pipelines.Centrifugal type units
These are universal devices designed for pumping a wide variety of liquids (drinking water, oil, acids). They are widely used in industrial production. The operating principle of the equipment is based on the rotation of wheels with blades and the transfer of centrifugal energy to the liquid flowing through the body. There are units that are entirely dependent on water - it must be poured into the chamber before starting (classical centrifugal principle of operation), and those that suck in air or are of the vortex type. The pump can be installed on a special raft (relevant for wells), immersed in water or located on the surface.
Advantages:
- good pressure at standard performance;
- low price;
- reliability with regular use;
- high maintainability;
- ease of maintenance;
- can be installed above the liquid level;
- Suitable for use in contaminated water.
Flaws:
- it is necessary to fill the pump chamber with water before the first start;
- Vortex-type models have a high probability of engine overheating.
The main purpose of units of this type is to provide watering and irrigation of agricultural land, connection to autonomous water supply systems, use for extinguishing fires and pumping out drainage fluid, as well as industrial use.
Surface Type Pumps
These are kind of sissies among pumping equipment, extremely sensitive to water pollution. Household units operate on a self-priming principle and can be centrifugal or vortex.
Advantages:
- budget cost of many models;
- ease of maintenance and installation;
- low energy consumption.
Flaws:
- increased operating noise of models with a built-in ejector;
- impossibility of using standard models without an ejector at depths greater than 7-9 meters;
- sensitivity to water pollution (the unit fails).
designed to provide housing with drinking water and irrigation of household areas (gardens and vegetable gardens).
Tools and materials
To install the pump you will need:
- Special adapter for connecting a pipe (nipple). It has an external thread at one end and an internal thread at the other. When purchasing a pump, you need to check whether such an adapter is included. If it is not there, you should immediately purchase a nipple of a suitable diameter.
- Coupling – fits onto the nipple and ensures reliable fastening of the pipe.
- Plastic clamps or insulating tape for attaching the power cable to the water intake pipe (relevant for deep models).
- Sealant for joints - tow with silicone sealant or FUM tape.
- Cable (to be purchased if not included with the pump).
- Cable or rope for hanging a well pump inside a shaft.
Installation process
The installation procedure may vary depending on the pump type.
Installation of surface models
They are installed in utility rooms or placed on a bracket directly at the well head (summer option).
Installation includes the following steps:
- connecting the water intake hose to the suction pipe;
- installing a check valve at the end of the hose;
- securing the filter (mounted behind the valve).
If an ejector is used, a system of two hoses must be inserted into the well - a suction hose and a pressure hose. The ejector, filter and valve are installed on the suction hose, and the pressure hose is connected to the side inlet of the ejector (an outlet is used).
Installation of submersible models
Such units are lowered directly into the water. The size of the pump must be smaller than the diameter of the well, that is, it is necessary to provide a gap between the walls of the well and the body of the unit for its free movement.
Installation consists of the following steps:
- the check valve is screwed to the pump nozzle;
- then a filter with a concave shape is mounted here - the device prevents siltation of the unit;
- a water pipe is mounted to the check valve (such models do not have a water intake hose);
- the second end of the pipe is fixed to the hydraulic accumulator (if it is located in a caisson chamber near the well) or attached to an adapter - a special adapter at the head of the well;
- the power cable is secured to the pipe with plastic clamps;
- a safety cable or rope is threaded into the brackets of the unit;
- the pump goes down (you cannot hold it suspended by the cable!);
- the pipe is fixed to the head with a coupling.
Important points
For installation to be successful, it is recommended to follow a few simple rules:
The lowered pump should not lie on the bottom. This will lead to silting of the unit. The optimal distance to the bottom is from 50 cm to one meter.
Holding a cable or bundle consisting of an electrical wire and pipe is strictly prohibited.
The unit is suspended using a safety cable. To prevent it from getting tangled, it is permissible to fasten the safety net to the main water supply pipe using plastic clips or insulating tape.
You should clearly determine the type of pump and the depth of the source:
- For a depth of 7-10 meters, a surface self-priming or submersible vibration pump is required.
- At a level of 15-20 meters, vibration and centrifugal pumps, as well as surface units with an ejector, operate.
- Deep submersible units are used in wells from 20 meters.
Switching on and operation
Pumps operating on the vortex principle (suction air) do not require filling the pump chamber with water. Classic self-priming centrifugal models must be filled with water before the first start!
One of the primary tasks of every owner of a suburban area is to provide drinking water to the living space. 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
In order for drinking water to flow uninterruptedly into a country house, it is necessary 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 will not work because 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, it is necessary to ensure the presence of the optimal voltage of the 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 the electrical wire needs to be extended, 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
At the initial stage, the casing should be carefully checked. There should be no narrowing, unevenness or curvature of the structure. The presence of any defects will make it difficult to properly install the deep-well pump and lead to its premature damage.
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 is best to use a 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 pull them strongly towards 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. The water pipe is connected 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.
The quality of operation and service life of the equipment will largely depend on the correct installation of deep-well pumps. 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.
