DIY sprut pump repair

Without submersible pumps, not a single well will function properly. This very robust-looking device really is, and is distinguished by its reliability and duration of operation without emergencies.

Connected submersible pump ready to be lowered into the well

Failure of submersible pumps is an extremely rare occurrence (of course - with proper operation). But if it happens, then timely repair of deep-well pumps is necessary in order to avoid additional, sometimes more serious, problems in the water supply system from the well. Fortunately, you can make such repairs yourself.

Due to the fact that the pumping device constantly interacts with water, it is constantly influenced by various negative factors. Fortunately, such negative factors rarely lead to lightning-fast breakdowns, usually the pump's performance is disrupted gradually, gradually and noticeably for the exploiters.

And this means that if small defects are found, it is not necessary to radically replace the deep-well pump, since you can do the repair yourself. By the way, replacing a submersible pump with minor breakdowns is practically never carried out at all. Submersible pumps are even easier to repair, including by hand, than submersible pumps.

In the overwhelming majority of cases of breakdowns of deep-well pumps, it is the magnet of the pumping device that fails. Such a breakdown is most often observed in submersible pumps of the "Sprut" and "Aquarius" brands. Unfortunately, in this case, do-it-yourself repairs will not work, since the equipment for repairing the pump magnet is available only at specialized enterprises. In such a situation, the pump must immediately be taken for repair to specialists..

Another thing is extraneous noise when the pumping device is running. Here we are already talking about a breakdown of a mechanical nature. In the overwhelming majority of cases, mechanical damage can be eliminated by hand.

The first step in case of extraneous noise is to disassemble the pumping device for parts. In cases where noises are heard from pumps of the "Sprut" or "Aquarius" brand, it is necessary first of all to check the electrical system of the pump, which includes both the engine itself and the automation system.

Subsurface pump with connected hose

Pumps of the brand "Sprut" and "Aquarius" have breakdowns most often in these systems, which, however, can be repaired quite simply with your own hands. Among other problems that often arise with pumps of the brand "Sprut" and "Aquarius" are breakdowns of the time relay and the protection system against short circuits or dry running.

The reasons for such breakdowns can be gradual blockages of the internal pumping system with foreign objects from the well soil. In addition, the operation of the pump in dry mode can also become a serious problem, since at such a "stroke" the oil quickly runs out, which leads to uneven and uneven operation of the internal mechanisms of the pump.

In such a situation, over time, the parts undergo deformation, up to the impossibility of repairing in principle. That is why any pumping device, especially popular in the CIS brands "Aquarius" and "Sprut", must undergo constant diagnostics for internal problems, preferably by specialists.

The rarest reasons for the failure of a pumping system are the following:

• overheating of the working fluid when its temperature exceeds 40 degrees Celsius;
• improper attachment of the submarine cable.

These problems are typical not only for pumps of the brands "Aquarius" and "Sprut", but in general for everyone, since the reasons that led to such problems are in no way connected with the quality of the pump, but directly depend on the professionalism of the pump installer.

If you find that the device is not working properly, you should not immediately try to fix it, even if the reason is obvious. Initially, you need to check the device for the presence of either minor problems that are not so obvious at the first inspection, or for the presence of a major problem, when it is initially not clear at all why the device does not work.

Submersible pump with accumulated deposits on the casing

On the submersible pumps of the brands "Sprut" and "Aquarius", as, indeed, on any others, the first thing we do is to check whether there was a banal overload, due to which the automatic device and the entire pumping system as a whole could turn off.

• disassemble the junction box;
• make a visual inspection of the inside - a burnt-out part will be immediately noticeable (a burning smell can also be felt).

If the cause of the breakdown is not clear, then you need to remove the impeller from the pump motor and check whether the motor itself rotates directly in a free state or not.

It is important to know that most modern pumping devices are manufactured in single phase. A so-called "smoothing capacitor" is connected to them, thanks to which the engine starts up more smoothly and smoothly. There is a special winding around it.

In such pumps, the engine most often burns out. Actually for this reason, it is necessary to remove the impeller. And after removing the impeller, you must try to scroll the shaft manually. Thanks to the pre-vacated space, due to the removal of the impeller, this is not difficult to do.

But if the shaft is not spinning, then you need to think about mechanical failure. To be more precise, you should think about engine jamming.

This can happen for the reason that small or, in other cases, large particles of soil constantly get into the engine.

This only happens if the engine does not have an additional protective filter. Actually, these particles can be the cause of such problems. It is noteworthy that if they are not promptly removed from the motor of the pumping device, then this will gradually lead to the fact that the entire stator winding will completely burn out. She, obviously, cannot be repaired, only replaced. However, if the shaft has no problems with rotation, then the lower part of the motor can be assembled.

Before starting to disassemble the upper part of the electric motor, be sure to place it in an upright position. This is really necessary, as installing the electric motor in the wrong position can lead to oil leakage, which is the working fluid in pumping systems..

After installing the electric motor in the required vertical position, it is imperative to remove the cover through which the power wires of the installed electric motor pass. Actually, when you remove the cover, you can immediately diagnose the starting capacitor for problems. To do this, it will be necessary to use an ohmmeter in order to check the resistance of both the starting and its own working winding.

Therefore, further you need to take the ohmmeter terminals and connect them directly to the winding itself. Next, you need to rotate the handle, which will then create the required voltage of 200 - 300 volts. When the resistance readings on the device do not reach infinity, and this has a certain value, it can be assumed that the condition of the winding is satisfactory or even ideal.

But in cases where the device detects resistance reaching infinity, we can safely say that there is a problem in the form of an interruption in the operating phase of the motor.

Blockage of the inside of the submersible pump

When the device detects too little resistance, we can say that there is a so-called turn-to-turn circuit. Unfortunately, if one of the above possible problems occurs, then an attempt to fix everything with your own hands will not be crowned with success, and the unit will need to be taken to specialists who have the equipment necessary for repairing.

However, in most cases, the problems described above require not so much a partial or complete repair as a complete replacement of all defective parts. Especially when it comes to winding.

If the device says that all the checked elements of the pumping system are in perfect working order, it is necessary to carefully examine the starting capacitor. Under such circumstances, most often the cause of a malfunction of the entire system is precisely its breakdown. In addition, it can be in a state of the so-called breakage.

Unfortunately, at first glance, this problem may not be striking, but when diagnosed with a special device, an ohmmeter, the malfunction will surely come out. And already in these cases, it will be possible to repair the starting capacitor on its own. However, most often, the repair of a starting capacitor can only be called a complete replacement, since its breakdown, and most often it is overheating and combustion of the capacitor, is a fatal breakdown.

Today, the problem of the lack of central water supply is solved quite simply. A wise and practical owner equips his own water supply system on his site - he drills a well, which is subsequently equipped with a special submersible pump. However, during the operation of even well-known brands, pump maintenance and repair may be required.

Using the example of SPRUT "QGDa 0.8-40-0.28", a step-by-step action plan will be considered, following which you can perform an independent repair of submersible pumps of various manufacturers.

Step # 1: Required Tools
When dismantling the SPRUT submersible pump "QGDа 0.8-40-0.28" you will need:
• Phillips and flat-head screwdrivers.
• Box and open-end wrench for 9.
• Metal brush and regular construction brush, medium hard.
• Auxiliary fluid for relieving the moment of unscrewing rusted bolts.

Step # 2: Dismantle the middle part of the pump
The most common reason when the device loses in performance (or simply stalls, as a result of which the pump does not pump water), lies in the contamination of the internal working components. In second place is the development of the auger and the rubber bushing associated with it. In both cases, such a process as disassembling the pump cannot be avoided.
• Before disconnecting the transfer hose - clean the pump from external contamination. As you can see in the photo, the case is especially difficult - the well was filled up.
• Disconnect the protective intake grill, which is fixed by means of 2 screws.
• Next, unscrew the 4 screws that hold the two main parts of the pump together.
Attention: use a special anti-corrosive liquid in order not to rip off the thread. In this case, a Mannol M-40 lubricant cylinder was used.

Step # 3: Cleaning the auger and analyzing its condition
As you know: water wears away a stone! Pay attention to the photo of the "spiral" element - its condition requires replacement. The cost of such a component, at the time of this writing (March 2015), varies in the price range of $ 20-25.
• To replace this part it is necessary to unscrew the worn twisted rod counterclockwise.
• Install the new auger in reverse order.
• As a rule, the mentioned element comes complete with a rubber bushing, which must be put in place of the old - worn out one.

Step # 4: Disassemble the top of the pump
To replace the rubber tube (for the auger), it is necessary to unscrew the 4 outer bolts.Remember, the softening fluid is a guarantee of the integrity of the fasteners being removed and the internal body thread. Disassembling the pump must not lead to new deformations and damage.
• Disconnect the structural elements and replace the rubber bush.
• Assemble the upper part of the body in the reverse order.

Step # 5: Checking the oil level
Maintenance of the pumps is required to prevent various kinds of breakdowns and bring the state of the device close to the factory one. Only in this case their work will be reliable and uninterrupted. Submersible pump SPRUT "QGDа 0.8-40-0.28а" is equipped with an oil-filled motor. Therefore, if the level of special fluid is insufficient (part of the winding is not covered), it is necessary to replace it completely. The most suitable for this is petroleum jelly (propylene glycol, less often glycerin).

Finally
When carrying out repairs to submersible pumps or their preventive maintenance, adhere to the ordered installation / removal scheme. Bolts and engravers must match their starting position. During the final assembly process, pay attention to the connection points of the pump housing. Of course, the fasteners must fit snugly enough to the chassis base. Do not allow the moments of "undershooting". Slots and obvious gaps will contribute to the moment of mechanical wear of the internal and external components of the pump being serviced. All the best to you and every success in the repair business!

We repair a borehole pump

If you have a well or a well at your summer cottage, then they will never work correctly without a deep pump. A device such as a submersible pump is seemingly durable and does not always work properly.

In our time, breakdowns of submersible pumps are very rare. But suddenly you have a pump failure, you need to pay attention to it in a timely manner and bring it into normal operation.

So that in the future there are no more serious consequences. You can also fix a deep pump with your own hands, if you do not want to call a special master.

The submersible pump is constantly in the water and is constantly influenced by negative factors. In most cases, submersible pumps do not break down instantly, but gradually fail. If you still have a small breakdown, then it is not necessary to replace the pump, you can do a little DIY repairs.

And it is not necessary to change a completely submersible pump with a small defect and it is not advisable. If we compare a submersible pump with a submersible pump, then a submersible pump is easily repaired by oneself than a deep one. Most often, the magnet of the pumping device breaks at a deep pump.

Such a defect is exposed in such pumps as "Aquarius" or "Octopus". If your pump magnet is out of order, then you will not be able to make repairs with your own hands, but only a replacement is provided in special services. There are such breakdowns as extraneous noise during the operation of pumps. And these are mechanical breakdowns that can be easily eliminated by hand.

Deep water pump device

First you need to put the pump upright and disassemble it for parts. If the pump makes noise during operation ("Octopus" and "Aquarius"), then first the electrical system of the pump is checked, which is responsible for the automation system and the operation of the engine.

The most vulnerable pumps of the brand "Sprut" and "Vodoley" in which noises are heard during operation. In this case, you can fix the breakage with your own hands. Breakdowns also occur in pumps such as "Sprut" and "Aquarius"; this is a relay malfunction, as well as dry running failure. Such breakdowns occur most often from clogging of the internal pump system.

Also, if you turn on the pump in dry mode, this can also lead to serious damage.And most often the submersible pump works in dry mode, it quickly runs out of oil, while the mechanism starts to work tightly and not smoothly. If the pump runs in dry mode for a long time, deformation of the internal parts occurs, as a result of which it becomes impossible to repair the pump with your own hands.

That is why pumps such as Aquarius or Octopus must undergo constant diagnostics and, preferably, by qualified specialists.

But infrequent breakdowns of the pumping system are pump overheating, this is when the unit heats up over 40 degrees Celsius, or you have incorrectly strengthened the connection cable. These infrequent breakdowns not only occur with such pumps of the Vodoley and Sprut brands, and other manufacturers.

If during operation you notice that the pump does not work as it should, extraneous noises are heard, then you need to take action immediately. We recommend checking the devices for minor problems first. On such brands of pumps as "Sprut" and "Aquarius", initially it is necessary to check whether a reboot took place, because of which the machine most often turns off, and then the pumping system.

Pump Aquarius and its repair.

To check this, you must first unscrew and disassemble the junction box. Inside this box, you can see a breakdown, and this is blackening or a burning smell. If everything is in order in this area, the smell is not felt, then proceed to removing the impeller from the pump motor.

First, it is checked whether the engine is spinning. A smoothing capacitor is connected to the engine, through which the engine is started. We also look at the winding around it, which should not be broken or torn. Most often, in these pumps, a breakdown is a burnout of the engine. That is why the impeller is removed to see this.

After removing the impeller, we begin to manually scroll the engine (shaft). If the shaft does not rotate, then mechanical failure is evident. In other words, the pump motor has jammed. Most often this happens due to the fact that small debris and soil can get into the engine. And this happens due to the fact that there is no protective filter on it. If in the future you do not clean the special filter and remove particles on it, then the stator winding in the engine may soon burn out.

ATTENTION! The stator winding cannot be repaired - only replacement.

Before you decide to repair the electric motor, you must put it vertically. If you do not, when disassembling the electric motor, oil will leak, without which the pumping system will not work. Further, in a vertical position, the cover is removed through which the 220 W power wire passes.

Immediately after removing the cover, it is advisable to diagnose the starting capacitor. To diagnose a starting capacitor, you need an ohmmeter. This is checked by connecting the terminals to the motor winding. Then we rotate the handle, and it creates a voltage of 250-300 volts.

If the device shows resistance at the same time, then it is considered that the condition of the winding is ideal. But if the ohmmeter device detects infinite resistance, then there is a problem in the form of a break. Conclusion: the working phase of the motor is not working, there is an open circuit.

If the device shows a small resistance, then we can talk about an inter-turn circuit. Conclusion from the above - on your own, if it happened, it is not possible to fix it. It is better in such cases to contact a specialist. Since in most cases, replacing parts will not help, but only replacing all successive parts will help. Especially if the pump winding has not been fixed.

When viewed further, we look at the pump further. The device shows that everything is in order, we proceed to inspect the starting capacitor. Most often, a breakdown occurs in it. In other words, there is a cliff in it.When the pump is operating, such a problem does not immediately catch the eye, but upon a detailed examination with such a device as an ohmmeter, the breakdown will come out.

At the same time, do-it-yourself repairs of the starting capacitor can be done independently, without resorting to the help of a master. But if this does not work out for you, then it is better to replace the starting condensate with a new one. Since starting condensate is a fatal breakdown.
