How to remove a stuck pump from a well - effective ways to solve the problem. How can a stuck or fallen pump be pulled out of a well? Pull the pump out of the well

If your pump is stuck in a well or has fallen into a well, check out our instructions. Lifting pumps should be done carefully, as there is a high probability of making a mistake and damaging expensive equipment.

5 Causes of Pumps Stuck in Wells

Before you pull the pump out of the well, you need to determine the exact cause of its jamming. This will make it possible to choose the most effective option for troubleshooting, which will reduce the risk of failure. pumping equipment.

There are 5 main causes of the problem:

Sagging power cable. This is the most common situation faced by every third owner of an autonomous water supply system. The main signs of the problem are not only the sagging of the cable when lifting the pump from the shaft, but also its winding around the equipment body. In this case, even the application of great efforts will not allow you to move the device.
Stuck in limestone. Rare maintenance of the mine causes stagnant water. Because of this, metal salts form limescale. It securely fixes the pump and makes it impossible to pull it up.
Well silting. Using the pump for several years and not wanting to carry out cleaning activities leads to the fact that a large amount of sludge accumulates at the bottom. It completely covers the body and does not allow you to lift the device up.
Mechanical damage. Most often, the pump is stuck in the casing, which was damaged as a result of a heavy object falling into the mine or inaccurate human actions during cleanup.
Hit by a foreign object. If it gets stuck in the pipe, then do not allow the pump to be pulled out of it.

5 ways to get the pump out of the well

Experts recommend using several proven methods that allow you to quickly fix the problem. To pull out a stuck pump, do not use excessive force, which can only damage the device and disable it.

How to get a stuck pump

To quickly get rid of the problem, you need to know how to get the pump out of the well if it is stuck and does not move. For every reason there is a solution.

This is how the vibration pump can get stuck in the casing

Available methods:

Cable slack. If this situation occurs, you need to slowly and carefully lower the device. As soon as it is at the bottom, loosen the cable and try to lift again. At the same time, they move slowly, trying to avoid sagging of the electric wire and other structural elements (cable, hose).
Silting. With such a problem, it will be difficult to lift a stuck device. To remedy the situation, silt deposits must first be washed out. To do this, carefully swing the cable, in parallel trying to lift the stuck device. Gradually, the "grip" of the silt will weaken and after a few minutes of such work it will be possible to raise the equipment to the surface.
Burrow in limestone. If such a problem occurs, you should perform all the same actions as with silting. Slow rocking will gradually break up deposits near the hull and allow you to lift the device from the bottom.
Pipe damage. To get stuck equipment will help rotational movements that need to be given to its body. Lift the device slowly, as one careless movement will be enough to damage its outer part.
Foreign object stuck in the shaft. In such a situation, you need to take the help of professionals, since it will be difficult to get this item with your own hands. This is due to the risk of it falling to the bottom of the well or damaging the hull.

What needs to be done so that the pump does not get stuck

It is difficult to get a stuck pump, so experts recommend taking all necessary measures to reduce the likelihood of a problem. To do this, you need to perform several activities.

These include the following:

Attaching the electrical cable to the hose. This simple action will help to avoid sagging of the wire and its wrapping around the body of the pumping equipment. Fixation is carried out using special clamps, which must be regularly replaced with new ones.
Placement of the pump above the filter. This installation option will avoid sticking to the body of silt, which often causes the device to get stuck.
Annual cleaning. Regular carrying out of this event will not allow silt and sand to accumulate at the bottom of the well.
preventive treatment. In this case, professionals recommend using citric acid for limescale removal. She will quickly deal with the problem and eliminate the possibility of the device getting stuck.
During the arrangement of an autonomous water supply system, only pipes should be used High Quality. Due to this, there will be less risk of breakage as a result of mechanical stress.

How to get a pump that has fallen into a well

If the cable breaks and the pump falls into the well, it will be difficult to get it from the bottom. Even if you manage to do this work, you will have to change the device to a new one.

Procedure:

Find a rod made of any durable metal. Its size should be enough to reach the bottom.
A special screw nozzle is attached to one edge, which is shaped like a corkscrew with a pointed end.
At the second end of the rod, a rod is fixed, which allows you to rotate a home-made structure.
lowered ready product and find fallen equipment.
Applying force, screw the screw nozzle into the body of the device.
As soon as it deepens to half its length, the pump slowly begins to rise.

What needs to be done so that the pump does not fall

Lifting a pump from a well is considered a difficult undertaking, so you need to try to prevent it from falling to the bottom. To do this, you need to take several steps. Among them are:

use the most rigid and durable cable;
use a one-piece long hose, and not assembled from several small pieces;
the pipe diameter should be selected in a ratio of 3:2 with the dimensions of the pump;
install a head on the well to prevent falling objects.

How to get the pump out of the well

Extraction of pumping equipment stuck or fallen to the bottom of the well is carried out in exactly the same way as for the well. Use a homemade anchor.

If the depth of the mine is more than 10 m, then it is recommended to contact companies involved in cleaning wells. Their workers have at their disposal special equipment, thanks to which they can quickly fix the problem.

If the pumping equipment is stuck in the well or is at the bottom of the well, you need to know what to do in such a situation. It is important to quickly take all necessary measures to reduce the negative consequences and eliminate the problem.

A pump stuck in a well is a major headache for many homeowners. Incorrect handling in such a situation can lead not only to damage to the equipment, but also to total loss wells. Having figured out the question of how to get the pump out of the well, you can save both effort, time, and money.

Why can hardware get stuck at all?

The reasons for which it is not possible to freely pull the pump out of the well may be different. The most frequent among them:

sagging cable;
well silting;
mechanical damage to the pipe walls;
foreign objects in the pipe.

And since the gap between the walls of the pipe and the equipment can be only a couple of centimeters, it is simply impossible to see what happened there without special equipment. Therefore, it is necessary to find out the causes of the problem by the symptoms.

To get the pump out of the well, you need a lot of effort and skill - you have to be patient

Videos will help assess the difficulties associated with the workover of the well:

Solutions for jams

Possible situation #1:

Symptoms: The pump is stuck in the process of lifting and does not move up despite considerable effort.
Diagnosis: This is probably the most common and most easily fixable problem: a slack cable that has wrapped itself around the pump housing.
What to do? Carefully lower the pump down, take up any slack in the cable and raise the pump again. When doing this, make sure that the cable, cable and hose do not sag.

Cable sagging is very easy to avoid. It must be attached to the hose with special clamps. Each time the pump is lifted, they will have to be removed and then new ones put in, but these are trifles compared to the efforts to pull out a stuck pump.

Possible situation #2:

Symptoms: It is impossible to get a pump out of the well onto the sand, which has served faithfully for several years without any problems.
Diagnosis: The well is silted up, the pump is blocked by sediments that can reach several meters.
What to do? The structure must be "swinged", carefully acting with a cable. It must be pulled up, then released until the pump can be torn off the sludge. Water will enter the lumen and the sediment will be gradually washed away. The pump can then be carefully removed.

This problem most often occurs if the well has not been cleaned for three to five years. Annual cleaning will minimize the risk of well silting.

To pull the pump out of the well, sometimes special equipment is used.

Possible situation #3:

Symptoms: The pump cannot be removed from a limestone well that has not been serviced for a long time.
Diagnosis: The situation is similar to the previous case. The wells are not subject to normal limestone silting, so it can be concluded that the so-called "reverse silting" has occurred. Its cause is the excessive deepening of the pump, as a result of which the water around it stagnates. As a result, the calcium and iron salts contained in the water combine with oxygen and turn into a precipitate that accumulates on the pipes and the end of the pump.
What to do? Attempts to flush the well to get rid of the plug will not be successful, because the sediment is very dense. As in the previous case, you will have to slowly and carefully swing the pump. At the same time, it is recommended to turn on the equipment so that the water erodes the sediment faster. Further Special attention should be given not only to regular maintenance of the well, but also correct placement equipment in it.

Possible situation #4:

Symptom: The pump is stuck in the middle of the well, you may hear the sound of a blow.
Diagnosis: The progress of the pump is hindered by damage to the pipe due to the fact that the joint has opened, a dent has formed, the edge is flattened, etc.
What to do? In this case, the pump must be carefully rotated. It is possible that the equipment will slip past the dangerous place, but the guarantees successful solution no problem.

Possible situation #5:

Symptom: The pump suddenly got stuck in the middle of the well.
Diagnosis: Some object was dropped into the well (a bolt, a pebble, etc.), which fell into the gap between the pump and the wall and jammed the equipment.
What to do? The most reasonable thing in this case is to call a team of specialists, since the probability of coping with the problem on your own is negligible.

"Folk recipes" for a stuck pump

In an attempt to save on the services of the brigade and independently resolve the issue of how to pull the pump out of the well, the owners summer cottages are very inventive. Often this is expressed in energetic, but completely wrong actions, such as:

Excessive force that breaks the cable or hose. All operations to remove a stuck pump must be done very carefully. Even when installing equipment, you should purchase a high-quality steel cable that can withstand increased loads.
Use of crampons and hooks and other similar devices to pull out a pump with a broken cable. If they break off and remain in the well, the task of removing a stuck pump will become several times more difficult.
Attempts to move a stuck pump with a crowbar tied to a rope or cable. Experts consider the scrap that has fallen into the well to be the most reliable "killer" of the well. Restoring her normal operation in this case is almost impossible.

And yet, several "power" techniques invented by craftsmen, may be effective. For example, you can select a cable and fix it in a taut state. Periodically, the cable is tapped, if after that slack appears, the cable is selected, pulled, tapped again, etc. The procedure can take several days.

Accessories must be securely fixed with a cable so that they do not fall into the well

Another method is to push the pump down with a weight. To do this, take a piece steel pipe suitable diameter, about a meter long. A metal “ear” is welded to the top of the pipe, on which a separate cable is fixed. After that, the cable, cable and pump hose must be passed inside this pipe.

The structure is lowered down so that, under its weight, the pump is moved from its place. When this happens, you need to carefully pull out all the components from the well at the same time: both the pump and a piece of pipe. It is worth considering that the weight of the device can reach fifty kilograms.

If the pump is stuck tightly, and it was not possible to move it by any means, it remains only to contact the specialists. Using special equipment, such as an underwater video camera, they can accurately diagnose the problem and offer the best solution. However, it should be remembered that such services are very expensive. In addition, not every well with a stuck pump can be saved. Competent design and arrangement of the well, use quality materials and regular maintenance will help prevent many problems.

Working with equipment can sometimes be complicated for reasons beyond our control. So, using a submersible pump for water intake, you can most likely encounter an unpleasant obstacle: it can get stuck in the trunk. In this situation, there are certain risks: you can cause significant damage to the equipment and spend a lot of time and effort to eliminate the troubles that have arisen. That is why you need to know what to do if the pump is stuck in the well. This will help a few simple rules and simple advice. But first of all, you need to figure out when it needs to be taken out and why it can get stuck.

Situations and causes

There are many reasons that cause difficulties. Most often, the pump is unloaded to the surface when it has already worked for a certain period of time underground and it is required:

carry out the necessary maintenance checks;
change the unit to a more efficient and productive one;
carry out repair work.

However, there are times when the device gets stuck when loading to a depth. This can happen if its size was incorrectly matched to the diameter of the pipe, and also if a foreign body got into the funnel that interferes with the descent. It is important to remember that the pump must be two-thirds smaller than the pipe diameter.

The equipment jams on the descent very rarely, because all measurements are made long before the work is carried out, and the probability of an error is practically reduced to zero, and extraneous things can be easily removed or, on the contrary, lowered below.

When carrying out this operation, you need to know about several rules.

It is necessary to conduct a detailed inspection of the pump for the serviceability of its components.
Control the absence of unnecessary items that can easily fall into the pipe (these can be bags, small boxes, packages and stones).
Work only with reliable materials: the cable and clamps should not raise doubts about their strength.

If you ignore these postulates, you can suffer significant damage. Both material and psychological.

Now to illuminate possible problems when lifting the unit, which happen much more often than the above points. Consider the most common reasons why equipment can jam.

Damaged casing walls

The walls were hit casing pipe, and damage to the seams and other parts of the weld, dents appear or flattening of the edges is observed. This can be identified by characteristic thuds. Most often, it turns out to get the pump on your own by slowly rocking. But this is only on condition of insignificant damage. Otherwise, the help of specialists will be required. To avoid this problem, it is necessary to responsibly approach the design of casing strings and the choice of device dimensions.

Better spend more attention and Money at an early stage rather than fixing bugs later.

cable sag

This unfortunate situation leads to the fact that the pump will be pulled out to the surface more and more tightly until it finally gets stuck at a certain level, because the cable wraps around its body and literally blocks it.

If this happens, you need to follow simple steps.

Lower the device to the bottom and eliminate the formed loop by measured rocking movements of the cable from side to side and its gradual movement upwards. It is necessary to remember about accuracy and avoid sudden and rough movements.
Monitor the condition of other cords and hoses to prevent the appearance of additional nodes which can greatly complicate the situation.
Fasten all elements with special clamps after a certain distance (most often this range is from one to one and a half meters).
Carefully remove stuck equipment.

This is a very common case, so do not worry: everything is quickly and easily solved. However, it would be better to prevent it in advance: when immersing the unit to the bottom, tie it in a pipe with an interval of about three meters. This will ensure that it is constantly tensioned and will help to avoid loops.

Foreign objects have fallen

Their arsenal is very extensive. It can be a nut, and a piece of cable, and stones, and packages, and packages. Here you need to try to remove the extra elements that have fallen, shaking the pump or trying to get them with a stick or hook. They can also be pushed down with a stick or other oblong object, however, be aware of the safety rules and that the pump can be easily damaged in this way.

All movements should be smooth and as careful as possible.

Pump skew

This is a serious problem with many causes. This can happen, for example, due to sagging or sharp jerks of the cable. The signs are as follows: up to a certain point, the ascent is carried out without hindrance, and at one moment it slows down, but there is no impact. Here you just need to make the cable tension weaker and try to turn the pump over.

At severe cases you can turn to the help of professionals.

The appearance of limestone deposits

In the worst case, they can form layers up to five centimeters thick. This is due to the reaction between oxygen and the metals contained in the well water. This problem can be solved by cleaning.

Cleaning the well with plain water directed inward under increased pressure. This will only work if the formations are small.
Using a solution of water and acetic/citric acid. It is important to note that this is only suitable if the pump has already served its purpose, because this method can harm the equipment.
mixture chemicals against scale and hot water

Silting wells

This can happen if the pump is used infrequently or if the operating rules are not followed. Thus, a kind of "trap" of silt is created. You can release the pump from it by alternately pulling and loosening the cable and parallel swinging the pump from side to side.

The material can also harden, which creates additional difficulties. In this case, it will need to be pre-washed out with a hose or fire hose. This is a rather time-consuming process that can take from several hours to two days. You can also check whether the equipment is “released” by trying to get it to the surface by swinging. If this does not work, then you need to continue to wait.

To avoid such problems, you need to regularly take time to clean the well and the filter.

Rope broke

This is probably one of the most unpleasant and difficult to fix cases, because here the device falls to the very bottom, and it gets stuck in the pipe. You need to act quickly. First of all, with a hose and electric cable stabilize the pump. If its dimensions and weight are unimpressive, you can try to unload it upstairs. Otherwise, a very strong rope with a metal hook should be used. Having hooked the unit with them, lift it up.

If he fell, "pulling" all the cables with him, you need to proceed as follows:

take an oblong object (a metal rod is best) long enough to reach the fallen pump;
attach a hook or corkscrew attachment to it;
put a metal bar on the free end of the rod (with its help, the structure will rotate);
lower the constructed mechanism down;
try to screw the hook into the pump housing;
gently and slowly pick up the fallen equipment.

It must be understood that this will be possible only at a shallow depth. In this case, the operation of the pump unloaded using this method is permanently stopped.

Unfortunately, there are cases when it is not possible to raise the equipment even with the help of professionals. Do not despair. It is necessary to seal this well and start building a new one, henceforth not repeating the previous mistakes and observing all the necessary rules.

Of course, if the equipment is still stuck, the most correct thing would be to immediately turn to professionals. After all, they have the necessary knowledge and skills to quickly and efficiently extract the pump. However, this does not mean that you cannot do it yourself. Here, as in any other case, it is necessary to approach the solution of the problem in detail, correctly and in a timely manner to identify and eliminate its “causative agents”.

How to prevent the pump lifting problem?

Pulling a deep well pump out of the well with your own hands, if it has come off, is not difficult at all if you follow all the recommendations of specialists.

The catchphrase says: "Forewarned is forearmed." To prevent the occurrence of unpleasant situations, you need to follow a number of simple rules that can save equipment, time and money.

Work only with strong cables. You can't skimp on this item. Choose quality products and fasteners.
The hose must be intact. Get it of sufficient length, even if the one that comes with the kit does not meet the required indicators. So you make the risk of breakage much less.
Choose the right size. The unit should be one third of the pipe diameter. Otherwise, congestion during lifting cannot be avoided.
Install headband. This will ensure the "protection" of the well from unwanted "guests": garbage, bottles, stones, boxes.

An “ETsV” or any other pump stuck in a well is unlikely to lead to an emergency situation throughout construction site. However, the problem of a stuck one can also result in the failure of the entire well system if attempts to pull it out are made incorrectly and without following certain rules.

Therefore, before, in fact, how to get the pump out of the well with your own hands, you need to familiarize yourself with the plan for carrying out such work and some of the nuances related to this situation. Only in this way can you be sure of your actions and their consequences.

1 What are the reasons for dismantling pumps from wells?

Pulling a submersible or "ESV" pump out of the well with your own hands can be very difficult for a number of common reasons, the most common of which are the following:

sagging wire;
Abundant formations of silt in the well;
Mechanical or other damage to the walls of the pump pipe;
Foreign objects caught in the pump pipe.

And due to the fact that the gap between the walls of the pump pipe and the equipment is almost always several centimeters, the cause of the breakdown without special equipment that comes with the starter-charger cannot be identified in most cases.

The question of how to get the pump out of the well with your own hands, without seeing the reason, is interesting and difficult at the same time, but we still solve it.

2 What are the reasons for lifting pumps and how to eliminate them?

There are only five most common and likely causes of difficulty in pulling submersible pump. You should study them very carefully.

Situation #1

Symptoms: In attempts to lift the pump, it simply does not move vertically upwards, even though serious efforts are made to lift.

Cause: Most likely, the problem is that there is simply a slack wire that is wrapped around the pump casing. Fortunately, this is the most common reason and, remarkably, easily solved by hand.

Exit: It is necessary to carefully and extremely carefully lower the "ECV" or any other pump down, select the "weak spot" of the wire and raise the pump again. When carrying out this manipulation, it is necessary to ensure that the wire, cable and hose do not exactly sag. To lift the pump, you can use the starter-charger.

If the pump wire has stopped moving, then it may have caught on something inside the well or wrapped too tightly around the pump. In this case, the algorithm for solving the problem is similar, only you need to act more carefully so as not to break the cable.

Situation #2

Signs: It is not possible to replace a well pump of the “ETsV” type, or to lift it, although breakdowns and problems during the operation of the pumping system have never been observed before.

Cause: Most likely, the well was covered with a dense layer of silt, which led to the blocking of the pump by sediments. It is noteworthy that such precipitation in some cases can reach several meters. This is enough common cause that . Protective covering pump filters, alas, in such cases is rarely a preventive measure.

Exit: It is necessary to swing the device in such a way that it does not particularly shake the cable. Otherwise, a serious problem and subsequent repair of well pumps is possible. To begin with, the cable used for swinging must be pulled up, and then released gradually until the pump is torn off from the sludge masses.

A large amount of water will enter the lumen and gradually the sedimentary masses will be washed out, after which you can carefully and carefully remove the pump with your own hands. In such cases, it is most acceptable and convenient to remove the "ETsV" pump with a starting-charging device.

Such a problem occurs most often in cases where the well does not undergo special preventive cleansing, which, according to the standards, should be carried out every three to five years. The device requires constant cleaning, preferably once a year. Such "prevention" will nullify the danger of silting of the cleaned well.

Situation #3

Indications: Pulling on limestone and subsequent replacement of the pump in the well is not possible due to the fact that the pump has not undergone constant diagnostic cleaning and performance testing.

Cause: This problem is very similar to the previous one. A well for limestone, especially the ECV type, in most cases is not subject to silting, which means that the first thing to think about is the so-called "reverse silting".

The reason for this misfortune is that long work, without proper maintenance, eventually leads to the fact that protective device the pump fails or simply does not work correctly.

Because of this, fluid gradually accumulates and lingers around the pump, which contains calcium and iron salts in large doses, which, when combined with oxygen, then turns into sediment, which, accumulating on the pipes of the pumping system, makes it impossible to pull the pump out of the well.

Exit: Unfortunately, the usual attempts to flush the wells with their own hands in order to try to get rid of the accumulated sedimentary plug will not lead to success, due to the fact that the sedimentary masses are extremely dense and durable.

As well as in the situation at number "2", here it is also necessary to slowly and carefully swing the pump. But only in this case it is necessary to turn on all pumping equipment in order to ground water eroded the sedimentary plug as quickly as possible. When pulling out the pump, it is best to use a starter-charger.

After solving the problem, in order to use the pump again without the possibility of getting the same problem, it is necessary to regularly service the wells and correctly, by all standards, place all equipment in it. In addition, it makes sense to install a protective device in the form of a sediment filter.

Situation #4

Signs: The pump is simply stuck in the center of the well. At the same time, the sounds of some blows are heard.

Cause: Most likely the pump is being hindered mechanical damage pipes that arose due to the fact that the joint parted, or a dent formed, or the edge was simply flattened. Moreover, there can be even more reasons for pipe damage.

Remedy: With this problem, it is necessary to carefully give the pump a slow rotational movement. In most cases, the equipment will simply slip past the potentially dangerous place and the problem will be solved, but, alas, there is a possibility that the problem will only get worse, which must be remembered when solving this problem in this way.

It is strictly forbidden to use a starting-charging device to give rotational movements to the pump. As well as pulling too hard on the cable. By such actions, you will only damage the pump itself or communications, but you will not achieve your goal.

Situation #5

Symptoms: The pump is simply stuck in the center of the well for no specific reason.

Reason: It is most likely that some foreign object has fallen into it (as a rule, these are bolts and pebbles of various diameters). At the same time, a foreign object with these signs, most likely, landed directly in the gap between the pump and the pump wall, which caused the equipment to jam.

Output: The problem is very difficult to solve on its own, therefore, the most correct and optimal solution experts will be called. Attempts to improvise and try to do everything yourself can lead to the fact that the entire downhole installation will be in an emergency state.

2.1 Incorrect methods for dealing with problems with stuck pumps

To save money, so-called "improvisational" or "folk" methods are often used. Their problem is that often solving the problem of pulling out the pump in this way turns into an aggravation of the situation. In order to exclude the possibility of such an aggravation, you need to know the list of obviously wrong and dangerous actions:

Excessive forced forces, which subsequently lead to a break in either the cable or the hose.
Using homemade "cats" or hooks to pull out the pump with a deliberately broken cable.
Solving the problem of a stuck pump with a crowbar tied to a rope, or less often a cable.

All of the above methods for pulling out the pump can lead not only to the aggravation of the situation, but also to an emergency condition at the entire well, which can result in huge financial expenses for the subsequent restoration of the entire system.

Therefore, it is recommended to always seek help from specialists, or, when solving a problem only on your own, the necessary literature and thematic recommendations. However, even with such preparation, it is possible serious problems. And this point must be taken into account without fail.

2.2 Examples of solving a situation with a stuck well pump (video)

Individual water supply is quite convenient to use and has a number of advantages: it provides independence from central systems water supply, and always clean and compliant water flows in the right volume. At the same time, the cost of performing work, equipment and materials fully pays off over time. At the same time, the equipment used in autonomous systems, is not insured against breakdowns and requires periodic maintenance.

A pump stuck in a well can be a serious problem, because the wrong action in this situation can lead to serious damage to the equipment.

Sagging electrical cable.
Accumulation of silt in the well.
Casing pipe damage.
Ingress of foreign objects into the well.
downhole during installation.

If the pump is stuck in the well, it must be removed with the utmost care and caution. Illiterate actions cause the final breakdown of the pump and lead to failure of the well. In some cases, only specialists with the necessary skills and with the help of special equipment can get a stuck pump. You can try to eliminate the simplest causes of jamming on your own.

An indication of a stuck electrical cable between the pump housing and the inner casing wall is the wire sagging when attempting to lift the pump to the surface. Additional physical effort or the use of auxiliary mechanisms (winch, jack or others) will not help solve the problem and will lead to a break in the cable or damage to the equipment. In this case, it is worth trying the initial position, lowering it lower, and carefully select the wrapped cable. Then remove the pump from the well, controlling the tension of the wire.

As preventive measure, preventing sagging, the cable is fastened to the pressure hose using clamps. Each time the pump is removed, the clamps will have to be disconnected, but, compared to emergency situations, this process does not take too much time.

If sludge accumulates, the pump cannot be lifted from its location. Depending on , the cause may be water stagnation and silting of the lower part of the pump (sand well) or the formation of mineral deposits above the casing (limestone well). In both cases, the swing of the included pump with a small amplitude is used, as a result of which the incoming water gradually flushes out deposits and makes it possible to lift the equipment. To prevent the formation of deposits, periodic cleaning of the well should be carried out, as well as at least once every 3-5 years, equipment should be raised for inspection and maintenance.

Damage, deformation or misalignment of the casing occurs as a result of the movement of soil layers, the use of an initially deformed or damaged pipe, or a poor-quality connection. When you try to get the pump, you hear the sound of a blow or tapping of the housing against the pipe walls. The passage of damaged areas can be helped by giving the pump a rotational movement when lifting. In this case, it should be borne in mind that excessive efforts will not help to pull out the equipment and will only exacerbate the problem.
Ingress of foreign objects (stones, tools, etc.) between the pump casing and the casing pipe, leading to jamming. In this case, getting the pump out of the well without the help of specialists is quite problematic. The use of special video diagnostic equipment allows you to accurately determine the location and type of interfering object and select best way problem solving.
If in the process, together with a cable, hose and cable, you can try to pry the cable with a steel “cat” fixed on a metal wire with a diameter of at least 5 mm. To do this, the free end of the wire, the length of which exceeds the depth of the well by 5-7 m, is attached to the boom of the lifting mechanism (crane, winch), and the second end is lowered into the well, after which it performs rotational movements until the hook is performed. It should be borne in mind that all work is done blindly and there is a high risk of equipment damage.

In order to pull the pump out of the well with minimal risk of damage to the equipment, it is important to maintain the same degree of tension on the cable and rope when lifting. For convenience, it is recommended to use a drum, on which the selected cable and cable are wound at the same time, preventing them from sagging.

"Folk" ways to remove a stuck pump

Attempts to save money and solve the problem on their own, with the help of improvised means and devices, are not always justified. Often, as a result of rash and hasty actions, a complete replacement of all pumping equipment is required, or even the drilling of a new well. At the same time, there are several "folk" methods that allow you to try to solve the problem with minimal risk of irreversible damage.

To push the equipment down, a hollow steel meter pipe with a welded metal loop is used. A separate cable is attached to the loop, and the “native” cable, hose and cable are threaded inward and brought to the surface. If with the help of an additional load it is possible to move the equipment from its place, all structural elements rise at the same time.

The relatively safe method also includes the method in which tension is created on the selected cable, and the stretched section is periodically tapped until slack appears. After that, the slack is selected and the tapping procedure is repeated. Such manipulations are performed from several hours to several days and are not effective for all cases.

Use of high quality cable and stainless steel mounting bolts.
The hose and cable must not have connections or knots.
The greater the distance between the pump casing and the casing wall, the lower the risk of jamming.
Be sure to use a cap to protect the well from foreign objects.
