How to get a broken pump out of a well. How to get a pump out of a well

Alexei 07.12.2014 Pumping stations

Those who use pumps sometimes encounter abnormal situations. One of them is that the unit is stuck in the well.

The trouble is that if it is not properly removed, the equipment can remain in the ground forever, and this already threatens with considerable losses.

How to get the pump out of the well so as not to break anything and destroy the entire water supply system? For this, it is necessary to observe certain safety measures during its arrangement and to know some rules for removing the device.

The main reasons and their solutions

What to do if the trouble has already happened and all attempts to do something do not give a result? The first step is to find out why this happened. And then it is already determined with the method of resolving the situation.

There may be several factors that provoked the breakdown. The most common reasons are:

Wire slack;
Well silting;
Mechanical damage to the pipe walls;
The presence of foreign objects in the channel;
Wrong choice of equipment.

Depending on this, the method of solving the issue is chosen.

Electrical cable slack

We take out the pump from the well

In this case, a loop forms and an overlap around the device, which leads to jamming. Now how to get the pump out of the well and what to use at the same time? Special tools are not needed here. The use of brute force can cause a rope or wire to break.

When raising the pump, the mount will have to be cut off each time, and then, when lowering, reinstalled. The procedure is laborious, but the safety of the equipment largely depends on it, so it is worth a little work for this.

If the pump is stuck and you have to lift it not by the cable, but by the hose or cable, which is generally undesirable to do, then it is necessary to make sure that there is no relaxation on any of the stretching elements.

Do not connect the cable and hose together with the cable attached to it. When lifting, a break may occur and this will cause the unit to tilt.

If the pump is stuck for this reason, you should first slide it back into the pipe, and then continue to lift. Everything must be done slowly, without jerks.

Well silting

This happens when the water intake is idle for a long time. You can pull out the device, but it will take a lot of patience. Since you can get the pump out of a silted well in only one way: by uniformly pulling and loosening the cable, as if jumping. Moreover, even the appearance of a small gap guarantees a positive end result.

Water will begin to flow into the formed space, it will erode the sludge, and it will begin to flow down, freeing the device. The main thing is not to make sharp jerks in order to prevent the cable from breaking.

Reverse siltation

Cleaning the pump

If a well is drilled in limestone rocks, then the water in it will contain a lot of salts and iron. Dissolved chemical compounds react with oxygen to form a sludge that covers the pipe walls. This happens especially quickly at great depths and with slow water renewal.

Accumulating on pipes and on the upper part of the mechanism, the sediment forms a plug, which reduces the channel cross-section. Even powerful units with high performance cannot cope with the accumulation of plaque.

Re-silting is usually detected only when trying to lift the device, after it is no longer possible to pull the equipment out of the well correctly.

To prevent such cases, you should adhere to two simple recommendations:

Take the equipment to the surface once every few years;
Choose the right level of equipment placement in the well.

But if this has already happened, then in this case the method of pulling into the swing is the most suitable. And this should be done when the device is running - the crumbling sludge plug will immediately be pumped out, freeing the pump.

Casing protrusions

It often happens that the pump in the pipe moves easily when it is lifted and suddenly runs into some kind of obstacle. You can lower the device down, but upward its movement becomes difficult. What prevents this and how to correctly pull the pump out of the pit in such a situation?

This could be due to a protrusion in the casing. Raise the equipment gradually, turning it around its axis. This rotational motion will help overcome the existing obstacle.

Foreign objects

They fall into the wells most often due to the fault of people. An example would be the use of a plastic bottle trim instead of a real rubber anti-vibration ring. And then an object falling into the channel can cause jamming.

It is better to prevent such a situation than to solve the problem later, how to get the pump out of the well. In this case, the best option would be to contact special services. An attempt to do everything on your own most often ends with a break in the cable. It is better to pay for the service, even if its cost is high, than to lose all the equipment.

Precautions

All these troubles can be avoided if you follow some rules when arranging a well. You should not save money by choosing a cable. It must be stainless, all other types and ropes cannot be used. And the fasteners must also be made of stainless steel, otherwise problems with how to pull the pump out of the well cannot be avoided.

Multiple hose pieces are not permitted. If there are connections, then breakage is possible during lifting, even a small piece can lead to jamming.

Of course, one should carefully consider the choice of equipment. Its dimensions should be less than the pipe diameter. By purchasing the device of the right size, you reduce the risk of jamming.

In order not to have to think about how to lift a stuck pump, you should not neglect the installation of the head. This will prevent debris from entering the water intake system.

There are situations when it seems that all the necessary measures have been taken, but the device is still stuck and attempts to pull it out do not give any result. How to get the pump out of the well in such a situation?

It's not worth experimenting. If you can't pull it out yourself, contact special services for help. Using video cameras and other equipment, specialists will establish the cause, and using various devices and tools, they will eliminate it.

Summary

The costs of dealing with accidents caused by pump seizure and borehole failure can be significant. To avoid them, first of all, you should take very seriously the installation of equipment and its timely replacement. Careful preventive care plays an important role in this. And then you do not have to put into practice all the information that you have learned from this article.

How to independently get the pump out of the well if the cable breaks or the device gets stuck in the casing. In both cases, you first need to correctly determine the cause, eliminate it, and only then raise the device to the surface. In order for the water pumping device not to remain in the well forever, it must be lifted correctly. Haste and unprofessional actions can disable the entire well, which will require serious repairs or the construction of a new water intake.

It may be necessary to retrieve the pump from depth for repair or replacement. Also, pumping equipment must be dismantled before cleaning the well. If the device comes out of the pipe with difficulty or does not move at all, there may be several reasons:

Overgrowth of internal pipe walls with lime deposits or sludge adhesion to them. The latter settles on the walls during prolonged downtime of the hydraulic structure.
Ingress of foreign objects into the water source, which can get stuck between the device and the inner walls of the pipe, stopping the upward movement of the pump;
Slack in the electrical cable. Ideally, the electrical cable and the cable should have the same tension - for this, when lowered into the depths, they are connected to each other using special clamps. If the cable is pulled down without being properly secured, it can sag and loop or wrap around the pump below the pump. It is these loops that will interfere with the free exit of the tool from the well.

In the situations described above, the integrity of the main safety cable is preserved. With its help, you will have to lift the pump, having previously eliminated the cause of the jam.

How to get the pump out of the well with a working cable

This situation can arise only in shallow wells "on the sand". If the inside is overgrown with silt, which, upon drying, turned into a solid substance, then first it must be soaked. To do this, small portions of water (1-2 buckets) are poured into the pipe through the head into the pipe, and the pump is swinging to the sides with the help of a cable. After a while, the softened sludge will drain from the side walls of the device to the bottom and the device can be pulled out. Sludge soaking can take from several hours to a day, depending on the degree of well overgrowth.

When overgrown with limestone

This situation occurs in limestone wells, which are very deep in themselves, plus limestone dissolves much worse than silt. You can get the pump out of the well yourself by acting on the deposits with special household products to remove scale from kettles, dishwashers or washing machines. The dry powder must be dissolved in the amount of hot water indicated on the package and poured into the head of the well. Simultaneously with pouring the solution, turn on the pump so that the water around it begins to boil. If you pour a lot of solution, and this will require 10-20 packs of descaler, then the limestone will begin to dissolve, and the device can be pulled out to the surface without any problems. If the experiment is not successful the first time, it should be repeated several times every 5-6 hours.

Descaling agent

When foreign objects get in

How to get the pump out of the well in this case? Only by rocking the pump in the hope that a stone or other obstacle will slide down and stop interfering with the removal of the pump. You can try to run a separate long, rigid cable with a metal rod attached to the end into the hole. With this rod, you need to try to push the barrier down. To avoid foreign objects entering the well throat, it must be securely closed.

When the electrical cable is sagging

When the cable sags, it is necessary to act according to the following algorithm:

Using a safety rope, lower the device to the very bottom and very carefully try to align the loop. To do this, the cable must be rocked in different directions, while pulling it upwards.
Align the tension on the cable, cable and water hose. It is better to do this with an assistant who will drag all three elements away from the mouth.
In the place farthest from the neck, fix three long components together. Fixation should be made in other places of their parallel arrangement. Fasten the cable, cable and hose with clamps every 1-1.5 m.
Pull out the pump and connect the deep parts of the cable, cable and hose.

How to get a broken pump out of a well

A rope break is the most difficult case. If, in the situations described above, the device is taken out precisely with the help of a cable, then if it breaks, you will have to pull by the water supply hose or by the electric cable. They are also attached to the device, but are not designed to be subject to significant physical effort. You can use this method if the pump in the well "runs" freely and is lightweight. If it is heavy, then it is better not to risk it, to lower a strong rope into the pipe with a metal hook attached to it. Use this hook to hook the pump and pull it up. In this case, the hose and cable can be used as belay if the hook is released.

You can get the borehole pump yourself if you know exactly the cause of the jam. Since the device is located at a depth, it is almost impossible to diagnose yourself. Improper lifting of the device can also have serious consequences. To prevent this from happening, it is worth contacting professionals - they have special video equipment for diagnostics. Having determined the cause of the pump stuck, specialists will extract it from depth using professional tools.

The well, of course, can be called an irreplaceable source of water supply on the site. But for a long service, she needs constant care. This can be both casing cleaning and prevention, repair and replacement of a pump in a well. Of course, to carry out such work, all equipment must be taken out. But sometimes a situation may arise that the pump is simply stuck, and there is no way to pull it out. But this is still the worst option. Sometimes inept attempts to get the pump out of the well lead to a break in the cable, which in the future will result in additional financial investments. In this article, we will tell you what to do if the pump is stuck in the well, how to pull it out as safely as possible!

Possible reasons

The most common cause of equipment getting stuck in a well is human error. This can be both a violation of technological requirements during the installation process, and the quality of installation materials. It is very important that during the installation process you choose proven equipment, and the installation itself is carried out by qualified specialists.

But improper installation and poor-quality equipment are only a factor affecting the reasons themselves. But why the pump can get stuck in the well, let's take a look below.

Loose cable

Sagging cable is one of the most common reasons that pumping equipment can get stuck in a well. If the electrical cable is slack, it may simply be bitten by the loop of the cable that holds the equipment. When this happened, in no case should you pull the cable with all your might, as you can rip it off, and it will be much more difficult to get the pump out of the well yourself.

It is worth noting that this is the most common and quickly resolved problem. If the pump is stuck and does not go up, try lowering it a little, and choosing a moment when the cable is loose, repeat lifting. During the process, make sure that the cable, cable and hose do not sag.

In order to avoid such troubles in the future, simply connect the cable to the hose with clamps, fixing it. When lifting, make sure that the cable and hose come out at the same time, and do not allow slack, as the situation may repeat itself.

Well silting

Quite often, the reason that it is not possible to pull the pump out of the well is its siltation, due to rare use. It is the silt layer that serves as an anchor that prevents you from pulling out the pumping equipment.

If silting is the reason, you can try to get it by swinging it, slightly raising and lowering the pump down. Under the influence of mechanical up and down movements, the water will wash away the space around the pump, thus helping to release it.

The casing can be heavily silted

If the pump is stuck, it is important not to rush during the rocking process, and not to pull with all your might, as it can completely jam or even break the cable. If you cannot get the pump yourself, you can resort to the help of firefighters so that they, by lowering the fire hose, wash away the silt layer with the pressure of water.

Important! To prevent siltation from happening, you need to regularly carry out preventive work to clean the well. Even once every 3 years will be enough.

Reverse siltation

One of the reasons for the pump jamming in the well can be the effect of reverse siltation. It should be noted right away that it is observed only in wells drilled on limestone soils, therefore, if your well is not on limestone, this option can be excluded.

Jamming of the pumping equipment occurs due to the deepening of the pump during operation. Over time, a sludge forms, which settles on the pipes and pump. It is important to note that you will not get off by flushing the well, as in the previous option, since the sediment can be very dense. In this case, you can pull out the pumping equipment by swinging it up and down, after turning it on.

Pipe wall damage

Damage to the casing wall is a rare cause of a pump stuck. But, nevertheless, it should be considered. If, while lifting the pump up, you encounter an obstacle and hear a knock, then most likely the problem is in the casing. This can be both its deformation (plastic), formed in the process of soil displacement, and defects in welding and pipe joining. In this situation, it is possible to get the pump out of the damaged pipe using rotational movements. By rotating the pump in a circle, you have a chance to go around the obstacle.

Another obstacle to lifting the pump can be an object accidentally falling into the pipe. If it gets into the space between the pump and the well, it can block the lift. In such a situation, as a rule, the downward movement is free, but when it moves up, the pump starts to wedge. Try to turn the pump and lift it up again. If there is no positive trend, it is better to call specialists who have all the necessary equipment to fix the problem and raise the pump.

Often, in order to get stuck pumping equipment, many people use, though effective, but rather questionable methods:

Use a metal cat. Although this method has some effectiveness, it should not be used. First, it is quite problematic to hook the pump, most likely you will hook the hose. And secondly, if the cat breaks off, you will later have to get it out.
Scrap is used. In order to push the pumping equipment into the well, scrap metal is often used, pre-fixing it with a cable. It should be borne in mind that if the scrap breaks, it is almost impossible to get it. Of course, one should not expect normal operation from such a well in the future. Instead of scrap, it is better to use a metal pipe, having previously welded the ears to it.

The pump can also be pulled out by tapping the cable. To do this, the cable must be constantly kept in tension and constantly tapped. In theory, if the pump is not completely jammed and there is no obstacle in its path, the effect will be positive, but this can take a long time.

How to avoid problems

Buy only high-quality rope for hanging pumping equipment. Cheap counterparts can lose their strength over time and cannot withstand loads.
In the middle of the casing, it is not recommended to use a spliced \u200b\u200bcable and hose, as under load they can disperse.
Purchase a small diameter pump so that the clearance between it and the casing is as large as possible.
It is better to purchase a head of a factory production in order to minimize the risk of various debris entering the well.

The normal functioning of an individual water supply system of a private house with a borehole pump depends on many factors, including how correctly and timely the equipment is serviced. External inspection of pipelines and joints, pressure control and accounting for the volume of the pumped liquid, changing filters all this significantly extends the service life of the equipment, but among all these operations, the maintenance of the deep pump remains the most laborious, during which non-standard situations are possible, for example, when the pump just might get stuck in the well.

Deep well pump stuck - the main reasons

Most often, pump stuck in the well casing is associated with several factors, each of which is unique in its own way and the ability to solve the problem of stuck equipment is not always justified by a universal technique. On the other hand, the situation when the pump cannot be raised to the surface is not so unique, cases when the equipment is hardly removed from the ground happen quite often and therefore this is not a particular problem for professionals.

Schematically, the situation when the pump somehow gets stuck in the well cavity is quite simple, and can be considered in the most common situations:

Jammed by a loose electrical wire;
Broken rope on which the equipment is suspended during lifting;
Ingress of a foreign object into the cavity between the casing wall and the pump casing;
Deformation of the pump casing or pipe walls;

As practice shows, most often, one has to deal with such situations with equipment that has not been serviced for a long time, so when planning maintenance, it is necessary to pay attention to this factor as well.

What to do if the pump is stuck in the well

A pump jam during lifting, as already mentioned, is not such a critical situation, and if the lifting is not done by professional well maintenance specialists, then the first thing to do is to be patient and pull yourself together, panic in this situation can only exacerbate the problem.

A simple analysis of the situation will help you quickly determine the causes of equipment failure and choose the best way to solve the problem. This requires:

find out the total depth of the pump installation;
roughly determine the depth of jam;
analyze how tight the cable is, determine if the pipeline and pump have disconnected and the integrity of the power cable.

inspect the casing head;
prepare the necessary tool for work;
clear the area from foreign objects.

Such an algorithm of work makes it possible to significantly reduce the time required to prepare for lifting equipment and prevent further major mistakes.

From simple to complex

For deep pumps with a large diameter and short length, the connection of which is carried out by means of a flexible polyethylene hose, and these are most often vibration pumps, during lifting, a situation may arise when the electric cable of the pump gets between the pump casing and the casing wall.

Such pumps most often rise by the cable and hose, but the cable, the entrance to the pump housing, which is located below the level of the hose connection and the cable attachment, is simply pulled up periodically. At the moment when the cable is most weakened and has excessive length, it fixes the rise of the entire structure. The small distance between the housing and the wall into which the cable enters, becomes a big obstacle to removing the equipment to the surface.

In fact, this is the simplest of all possible jamming situations when lifting. The problem here can be solved quite simply - it is enough to lower the pump a little into the well and at the same time pull up the cable. After tensioning the cable, continue lifting, observing the tension of all elements - the hose, cable and cable.

The situation when the cable breaks and the whole structure slides down happens quite often. Usually, the metal cable does not break, just the fixing elements, over time they are unclenched due to metal corrosion, the thread is not able to fix the mount and the cable is released. For the metal of the wire rope or wire rope, alloys that do not corrode or structures that have an additional protective plastic sheath are usually selected. But an ordinary steel cable, being constantly in a state of tension, in the place of fixation, abrasions and a focus of active corrosion can form, because the pump during operation experiences vibration, which is transmitted to the cable.

In this case, it is recommended to continue lifting if the well is shallow and the pump is lightweight, using a hose or pipe as the main lifting device. The upward feed should be smooth, without sudden interceptions and jerking. The use of a cable as a lifting element is not permitted! With this method, it is necessary to prevent the pump from rotating around its axis, since if the pump is jammed, a pipe or hose can be disconnected, which will further aggravate the situation.

A broken pump at the bottom of the well is also not the best option for the job, but if the power cable is intact and still attached to the pump body, then the chances of lifting the equipment increase significantly. For centrifugal pumps, auger pumps and vibratory models, the cable usually has an entry into the housing just below the outlet and almost at the level of the holes for the cable attachment.

For lifting, a device made of a piece of metal pipe and welded wire, on the one hand, and a lifting cable, on the other, can be used here. The cable is threaded into the pipe to the bottom, with which the wire is welded and bent in the form of a hook. The hook is lowered along the cable and, having reached the lowest point on the pump body, is inserted into the cable eyelet. Such an operation is somewhat similar to winter fishing, when the bait is slightly tugged to attract the fish, and the lifting hook should also hit the eyelet with small up and down movements and hook the pump.

A well in clayey soils, a sandy layer is most often prone to siltation. The situation when the soil enters through the drainage holes into the inside of the casing and settles without allowing the equipment to be lifted is most often typical for wells that are held for a long time without maintenance.

For circulation or screw pumps, this is quite painful, since they have rather impressive dimensions, and the sludge does not just settle, but is compacted tightly between the pump casing and the walls of the casing. In this case, when it was not possible to pull out the pump the first time, it is necessary to apply the tactics of gradual release from the bottom sludge.

The pump is alternately raised and lowered, first by 5-10 mm, and then. When the mud plug begins to saturate with water and erode, gradually freeing the pump housing.

Intrusion of foreign matter between the casing and the casing

The problem of small stones, pieces of metal or fasteners getting into the cavity between the casing and the borehole wall can have very large consequences, such as wire breakage or deformation of the casing at the splice.

Most often, a small stone or fastener gets into the well during repair or installation of equipment. The operation of the electric motor with low vibration can contribute to the passage of such a foreign object through the cavity until the moment when it does not completely fix the engine.

There are two main extraction methods:

pushing a foreign object to the bottom of the well;
release the pump with a powerful jerk.

The first method allows you to free the equipment if it is possible to lower the case down a few centimeters. It is important here that there was an opportunity to "swing" at least 1-2 cm, so that the structure began to move, and the stone gradually moved along the body. A rise of 2-3 cm to the next place of stupor should alternate with a lowering of the structure by 1-1.5 cm.

The second method must be used very carefully. A sharp jerk can damage the cable, therefore, if the fixation is rigid and the movement is not traced, it is recommended to lift it with a uniform force, literally "pulling" the pump along the well.

The process of deformation of the casing quite often occurs due to soil displacement or activation of underground sources, the transformation of a simple underground stream into a bubbling stream and even a river. Such changes in the structure of the soil in the area from the surface are not immediately noticeable, but with respect to the well, a large number of problems arise here.

For wells with metal casing, deformation is most often expressed in a change in the inner cavity of the pipe - collapse, bending or fracture. For wells with asbestos-cement casing, material is destroyed, couplings are crumbled, and soil enters the well.

For wells with PVC casing, bending or compression is most common, making it difficult to lift the pump.

The best solution under such circumstances is the decision to turn to professional builders to retrieve the equipment. Only having all the necessary arsenal of search equipment, from a remote video camera to a multi-section bar with hooks, in such a situation, it becomes possible to get the pump.

However, when the well is relatively shallow, only 8-10 meters, it is possible to design a sectional bar with hooks at the end to extract equipment from a shaped pipe and try to independently explore and retrieve the pump.

Usually, first, the distance to the place of deformation of the barrel is determined, then an approximate calculation of the internal cross-sectional area is made and an analysis is made of the possibility of extraction through the narrowest point of the pump bend, and only after that it is lifted.

It may be necessary to remove a borehole pump submerged to tens of meters for various reasons. And during lifting, an unpleasant situation often arises when the unit is stuck or, even worse, fell down. What to do if the pump is stuck in the well and how to lift it in the easiest and safest way? There are several reasons for these troubles, which will determine the choice of actions to remove the equipment. In no case should you panic and use brute force: this can result in damage or loss of equipment (the cable may break and the unit may fall down), water intake equipment and even complete loss of the well.

Downhole pumps are manufactured in such a way that their geometry most closely matches the cylindrical shape of the casing and its diameter. The average diameter of the pumping equipment body is 10-15 cm, and usually a small distance remains between the walls of the well and the unit - only 2-4 cm. Therefore, pumps can get stuck quite easily.

Fig. 1 Modern borehole pumps

How to get the pump out of the well if it is stuck? It all depends on the reasons why the equipment remains inside, despite the efforts being made to remove it. The most common factors that interfere with the smooth removal of pumping equipment are:

wrapping a dangling or loose cable around the equipment case;
silting up in the absence of maintenance;
various damage to the casing;
falling objects between the walls of the unit body and the well.

Before pulling the pump out of the well, it is recommended to observe the situation while attempting to retrieve the equipment. According to some indirect signs, it can be established for some reason the unit cannot be removed outside. If possible, a special video camera is used, which is immersed in the well and transmits the image to a PC monitor, allowing you to accurately establish why it is impossible to extract the unit.

Cable wrapping

During lifting of stuck pumping equipment, it is not uncommon for the power cable to be in a free state without additional fixation, which is why it sags. When removing the equipment, it often wraps the broken wire around the body, forming a loop, which makes it impossible to lift the unit up. The main sign that a winding has occurred is the complete immobility of the unit, which remains in place even with significant efforts when trying to lift it.

Fig. 2 Coiled pump cable is one of the common causes of problems when pulling out of a well.

There is no need to forcefully pull or pull the cable: it will break off and the apparatus may be lost forever. The solution to this problem is simple: you need to lower the equipment back to the same depth, loosen the cable to increase the diameter of the loop, and then gently pull the pump up again. In most cases, the equipment is pulled out on the first or second try.

Well silting

If the well has not been cleaned for a long time, then it is very likely that the pump is sucked in a layer of silt, and it will be blocked by a thick layer of sand, clay or limestone, which can be up to several meters thick. To remove the pump in such a situation, you need to be patient.

The way to release the equipment from under a thick layer of sediment takes time: it is necessary to slowly get it out, gently "swinging" the cable up and down, so that the particles of sand or clay gradually sag along the edges of the case. Once the sediment has been washed away with water, the pump can be removed without hindrance. In the future, it is necessary to regularly clean the well in order to avoid re-suction of the equipment into the sludge layer.

Casing wall damage

During long-term operation of the well, various damages often occur. If, during lifting, the pump is stuck in any area, and when trying to lift it, a mechanical obstacle is felt and a sound of impacts is heard, then the problem is pipe damage. On its inner surface, a dent, chipping, divergence of the weld and other similar damage could form.

To safely remove the equipment, you must give it a rotational motion to enable it to overcome the obstacle. However, in this case there is no guarantee that the pump will come out on its own. In some cases, the situation may turn out to be hopeless, and a new well will need to be drilled.

Object hit

If during the operation of the well some object fell into it - a bolt, a pebble - then this can firmly block the unit and, unfortunately, it is very difficult to cope with such a problem without the help of specialists. In most cases, you have to call a team with sounding equipment. If you're lucky, experts will offer the best solution, but most often you will have to sacrifice technology.

The pump came off and fell inside

If the cable holding the equipment breaks and the submersible pump falls into the well, careless and unprofessional actions on the part of the well owners can lead to irreparable consequences. Therefore, it is better in this case also to call specialists armed with special equipment and a set of cables for extraction. Even if you believe in yourself, lifting the broken off pumping equipment from the bottom of a well or well will be technically difficult.

Fig. 3 Crane to retrieve the pump from the well

Since the depth of the wells is usually several tens of meters, then for lifting you will need a special shaped load, a crane or one or two winches, a long thin cable, special gripping organs (crampons), metal wire, canvas gloves. In the process of lifting, you will need to take care of protection against falling foreign objects.

All this requires a balanced and thoughtful approach, and the optimal solution in 99% of cases will be to contact a specialist. Do not risk the well, but entrust the professionals to lift the fallen pump!
