A drainage pump for a well is used quite often. There are drainage pumps for pumping water, and there are drainage pumps for pumping water.
Therefore, you must first understand what needs to be done and then make a choice. After all, there are quite large and powerful units.
If you have a large system, then it is likely that you will need not just a pump, but a sump pumping station. Therefore, it is necessary to decide immediately on the scope of work. Today we will deal with the question of how to choose a drainage pump.
We decide on the tasks and choose
A drainage pump for a well is often used for pumping. They are used in cases where well water is not highly contaminated.
Here the question will also arise about the volume of water. After all, there are low-power drainage pumps that are not able to withstand heavy loads, but nowadays there are already models that provide a touch sensor for drain pump.
These are more powerful units, but accordingly their price is much higher. Let's consider the application features, types, as well as the pros and cons of these devices.
Application of drainage pumps
Let's immediately look at what a drainage pump is, what it is and where it is used.
Such devices are very useful under the following circumstances:
- If it is necessary to pump out water after accidents,
- When the level groundwater rises high enough
- In basements and basements when flood waters accumulate,
- In case of prolonged and heavy rainfall,
- To clean artificially created water bodies, for example, swimming pools, to comply with hygiene standards, they are cleaned using drainage pumps,
- To organize irrigation of large areas by drip,
- For decorative fountains drainage pumps are used to supply water to them. A drainage pump with a chopper is often used here.
Classification of drainage pumps
Now let's see how to choose the right one. Now let’s decide what the pump is needed for and where it should be used. You can also see everything in the photo. Such devices can be divided into two main groups.
Submersible drainage pumps
These devices are placed at the bottom of the object being cleaned before use. They are quite popular among summer residents and owners of private houses, since the use of such devices is not difficult, they are easy to install and replace yourself.
Among other things, submersible pumps are not very expensive, which is also their strong point. Depending on the principle of operation of the devices, they are distinguished:
- submersible type,
- Submersible vibration pumps.
In addition to the characteristics already listed, submersible drainage pumps have other features:

Drainage pump for a well: how to install correctly
Installation and operation are quite easy. But for proper operation For the device and its long service life, the installation of the drainage pump must be carried out according to certain rules.
After purchasing and unpacking the purchased equipment, you must check whether the contents correspond to the package, and also pay attention to special attention instructions included with this model. It is very important to study the existing limitations in the use of the purchased type of pump.
You can only make up general instructions which can be used to guide you when installing a drainage pump:
- A pressure line is connected to the pressure pipe, which can be a hose or pipeline, after which it is secured with the existing connecting parts.
- If the pump design has a float switch and the pump is used permanently, a check valve is installed on the pressure line.
- The device with a three-phase motor is checked to ensure that the direction of rotation is correct. To do this, the pump is installed on a straight surface, it is turned on and immediately turned off. During this process, the direction of rotation of the shaft is monitored:
- clockwise - correct connection,
- against - the phases need to be swapped.
- For a device connected to a pipeline, the correct direction is checked as follows:
- connect to electricity and measure the flow,
- turn off the power, swap the phases and do the same as described in the first paragraph,
- the supply power in the first and second cases is compared from which it is determined correct method phase connections.
- The device is placed in a vertical position with the pressure pipe facing up.
- The pump is lowered to the bottom of the well.
Using a sump pump to clean a well
In the process of selecting the appropriate type of drainage pump, it is very important to carefully study the instructions supplied with the device, since certain models can only pump clean water. At the same time, there are pumps that work well with contaminated water, including those containing small inclusions and fibers.
Attention: When the well for a long time has not been cleaned, it is better to give preference to a drainage and fecal pump that can pump water with heavy contaminants. Such devices contain cutting or crushing wheels, which crush large inclusions during operation.
For easier well cleaning, it is better to use drainage pump models equipped with a float. Usually this role is played by a certain switch that floats on the surface and turns off the pump when it reaches the bottom.
Otherwise, the operation of the drainage pump must be constantly monitored to avoid overheating of the engine, since the water in which the unit is immersed cools it.
A person does not need to dive into the well on his own; the drainage pump works automatically, but it must be configured correctly:
- First, the pump is immersed to a depth of 1 m without reaching the bottom,
- The device turns on, as a result of which the water is cleared from dirt,
- Next, clean water enters the well under pressure, which leads to the destruction of silt build-ups at the bottom,
- During operation, the pump periodically rises to the surface and its filter is cleaned. These steps are repeated until silt deposits appear on the filter.
Attention: In some cases, after major cleaning, the drainage pump is left in the well, which allows it to be kept clean. At the same time, clean the filters of the device every six months.
- For major cleaning work, it is better to use a powerful pump, but for maintaining cleanliness, a less powerful device is also suitable.
- Recently, the following practice has been very often used: the well is cleaned with a powerful pump a couple of times a year. The cleaning itself usually takes about a week, after which the pump is stored in a dry, clean room.
The use of a particular model of drainage pumps depends primarily on specific circumstances: the degree of contamination, the depth of the well, as well as other conditions. Depending on what characteristics a particular pump is endowed with, its cost will also be determined.
All the work is done with your own hands, so there will be no costs. Before purchasing, the instructions must be fully studied and after that you can make a purchase.
Many owners of country and private farms not connected to a centralized water supply are familiar firsthand with the problem of supplying water to their home and personal plot.
The “Malysh” submersible pump will help partially solve this problem; although it is not a powerful device capable of pumping water from artesian wells, it can cope with supplying water from wells, shallow wells and open reservoirs.
For those who are just planning to arrange autonomous water supply, as well as users of pumping equipment, it will be useful to learn about the design, operating principle and operating rules of the unit. We will describe in detail how to install the “Baby” in a well and ensure its uninterrupted operation.
Submersible pumps of the “Malysh” series are produced by the Russian company Livgidromash, whose history goes back almost seventy years. During this time, more than three million units of various pumping equipment rolled off the plant’s assembly line.
The use of a filter will not only extend the life of the unit, but will also ensure the supply of higher quality water, purified from any impurities.
Malysh pump maintenance
In order for the pump to serve for a long time and properly, it is necessary to comply with the operating and storage conditions recommended by the manufacturer. In this case, the manufacturer guarantees its normal operation for two years. The pump does not require complex maintenance and care, and simple rules It won't be difficult to do.
After the first installation of the device in the well, you need to let it work for one or two hours, and then remove it and carefully inspect the body and components to detect any malfunctions. If everything is fine, then the vibration pump can be put back in place and used further, leaving it immersed in water for a long time.
Periodically, at least once every three months, and if possible, then every hundred hours of operation, the unit must also be inspected. If traces of friction are found on the housing, it means that it was installed incorrectly and during operation came into contact with the walls of the water intake excavation.
To avoid this, you need to set it level and put an additional rubber ring on the body.
If the inlet holes become clogged, they must be carefully cleaned without damaging the rubber valve. For cleaning, it is best to use a tool with a blunt end.
If the pump is not used in winter, it must be removed from the well, washed and dried thoroughly. When storing the unit, place it away from heating devices and also protect from exposure to direct sunlight.
If, while following the manufacturer's recommendations, a breakdown occurs due to reasons beyond the user's control, the pump should be taken to a repair shop. service center. A list of popular breakdowns of the “Baby” pump and ways to eliminate them are described in.
Submersible pump “Baby” - convenient and inexpensive household appliance, easy to use and easy to maintain. Of course, due to its small power, it is not capable of providing full water supply to a private home, and, in fact, no one sets such tasks for it.
The inexpensive vibrator is perfect for seasonal use. He will become a real assistant summer cottages. Thus, with the help of “Kid” you can organize watering of plants and water supply from wells, wells or open reservoirs.
Do you have experience installing or using the Baby pump? Please share information with our readers, tell us about the specifics of the unit’s operation. You can leave comments and ask questions in the form below.
Advantages of screw electric pumps:
- noiselessness, since the internal parts are carefully processed and do not create friction;
- repairs can be carried out outside the service thanks to the simple internal structure;
- the screw shaft is a cast structure that is resistant to various operating positions of the device and does not break.
Important! If you choose deep well pump for a screw type well, you can count on long term operation and the ability to use in any situation for various types liquids.
Centrifugal and vortex
The centrifugal pump is the most popular model among residents of the private sector, which, however, is not without some disadvantages. Water supply principle centrifugally sooner or later leads to damage to the impeller - dents and metal cracks appear on it, which can reduce the efficiency of the equipment or even lead to its shutdown.
A centrifugal pump is a productive device capable of create a large flow of water. It is suitable for organizing water supply for a private home with a large number of water intake points.
The downside is that such equipment can only work for a long time with clean water, free from dirt and sand. If you choose a centrifugal electric pump with a top water intake, you can reduce clogging, since the suction device is located at the top of the device and is less susceptible to sand getting inside. In this case, the water in the well will not be pumped out completely. If this is not important in a private house, then the best one is a centrifugal one with an upper water intake. And vice versa, if you need to completely drain the container, then you need a device with a lower water intake - for basements, swimming pools, storage tanks. Which one is better and more necessary on the farm is the one they choose.
Surface pump prices
surface pump
Vortex electric pumps are desirable use only in clean water . The presence of sand leads to rapid equipment breakdown. Low efficiency does not allow for high pressure, so such equipment is not suitable for the water supply system of a private home.
How to choose a pump for a well
To accurately select a deep-well pump for a well, you need to consider the following parameters:
- distance to the water surface;
- performance;
- pressure;
- water needs on site or in the house.
To calculate the pressure correctly, needed to the depth of the well (indicated in technical documentation) add 30, and for reserve multiply by 10%. For example, the total depth is 30 m, add 30 - it will be 60. Multiply by 10% - it will be 6. All pumps have an indicator of up to 8 m. This means that an indicator of 6 m is quite suitable.
A family of 4 people needs about 200 liters of water per day, which is 40 liters per minute. For home needs, this performance will be sufficient. If you take into account the plot of land that needs to be watered, then you need to purchase a pump with a reserve.
Attention! An important parameter of submersible equipment is price. Don't buy an electric pump that's too cheap, because the quality of connections and tightness of the housing leaves much to be desired.
After the first repair, and it breaks down quickly, the unit will be unusable. Submersible pumps are mounted in such a way that they cling to a cable and descend to the bottom of the well. The price will also include a cable. The machine for connecting the device is not included in the price of the kit, so you need to provide for costs.
Popular brands
Russian submersible well electric pumps are popular on the market due to their low cost. The brand “Dzhileks” holds the lead.
A variety of models for all occasions allows you to choose quality device for specific purposes- For drinking water, pumping dirty water with impurities, sewage pumps. At a fairly low price you can buy a good, durable device that is resistant to.
According to statistics, every second water pumping device in the world is produced by the Danish company Grundfos. Prices for such equipment are much higher than in Russia. The quality is confirmed by certificates. The company represents a wide model range water pumping devices. When choosing Grundfos brand units, you need to know exactly what parameters the pump should have.
Long-term operation without the need for repairs is different pumping equipment from Wilo. The warranty period is 10 years. At correct installation and operation, the device can last 3 times longer.
The Italian brand Pedrollo has been operating on the market for a long time and represents pumping equipment of all types - surface, submersible, semi-submersible.
Important! The best submersible pumps for household use- these are those that fully satisfy the needs of the house and garden plot and do not require constant dismantling and repair.

Pumping equipment is not the equipment on which you need to save. A good unit will work for a long time and without interruptions, but the cost of high-quality devices will be higher. If you take your time and listen to the opinions of consumers, you can avoid mistakes in purchasing and operating equipment.
In this case, you can, of course, use a traditional metal bucket on the gate, or you can use a submersible well pump. Its use is advisable if the depth of the well shaft exceeds 8 meters. In other cases, you can use surface pumps. The option with a pump also has many advantages.
Advantages of using a submersible well pump
First of all, this is, of course, the high power of the device and the ability to provide continuous water supply. If with an ordinary bucket you can pump up from 8 to 15 liters of water at one time - depending on the volume - then with the help of a pump you can pump out tens of liters within a minute, without taking breaks and without expending any effort at all.
Submersible well pumps Quite easy to install and operate. WITH installation work Almost anyone can do it. To do this, it will only be enough to fix the device on a special suspension and, lowering it to the required depth, plug it into the electrical network.
Also among the advantages is the ability to supply water to fairly high heights - up to 80 meters. Thanks to this, even residents of high-rise buildings will not be without power.
Finally, it can be noted that submersible well pumps are made from special materials that are extremely resistant to corrosion and many chemical reactions. Typically this is stainless steel and plastic. This also makes the pumps resistant to the abrasive effects of particles in the water.
What types of well pumps are there?
The modern selection of such products is so large that you can choose the necessary element for any design.
Today there are many pumping well stations on the market. They can be divided in different ways, depending on the purpose of the classification. For example, based on a design point of view, well pumps are:
- Vibrating;
- Centrifugal;
- Superficial.
It is also possible to classify based on the methods of water supply and its quality. It is not surprising that the consumer is faced with a truly serious choice problem: which pump is best to choose? Some advice on this matter will be given below. In the meantime, it makes sense to consider in more detail some types of well pumps.
Submersible centrifugal pumps for wells
Operating principle of a submersible centrifugal pump.
Externally, such pumps resemble a metal (stainless steel) cylinder. Inside the housing there are: a centrifugal motor in a sealed casing, as well as a special impeller for removing water.
Pay attention! Such pumps do not have their own cooling system. Therefore, it is highly recommended, firstly, to operate by immersing the pump entirely in water, and also to ensure that the temperature of the surrounding water does not exceed 40 degrees Celsius.
The worst enemy of any submersible pump is accidentally turning it on “dry,” that is, without water. As a result, engine failure is almost inevitable. To prevent this from happening, today almost all types of pumps are equipped with dry start protection systems:
- Floats are the most common type of safety device. The method is quite reliable, moreover, it is also simple to implement, and also inexpensive;
- Bimetallic switches;
- As well as electronic automatic fuses - these are recommended in places where there is a constant change in water level. They have one drawback - quite a considerable cost.
Centrifugal pumps can provide immersion depths of up to several tens of meters and provide pressure to a height of up to 60 meters. They are also characterized by excellent productivity - up to 3-4 cubic meters of water in one hour.
However, such a pump also has a drawback. This is the probability that technical oil will leak out of it. This can happen as a result of violation of operating rules or breakdown for one reason or another. Collecting engine oil in this case can turn into a real headache.
Submersible vibration pumps for wells
If you do not need to constantly provide systems, but only from time to time, then excellent option can become so-called vibration pumps. They also belong to the category of submersible. Among their advantages are ease of installation and maintenance, high degree reliability and durability, providing fairly high water pressure - the ability to lift liquid to a height of up to 60 meters, as well as an affordable cost.
Scheme and appearance submersible vibration pump.
However, it was not without its drawbacks. The main disadvantage of such units is their relatively low productivity. Therefore, they are used mainly in occasional cases. In addition, vibration pumps cannot be used in those wells that were built on quicksand, since as a result of vibrations the quicksand may be activated. Because of this, in turn, there may be a rise in the bottom of the well and a decrease in its volume.
Submersible drainage pumps and their use in wells
Such pumps can be recommended not only if it is necessary to quickly supply water in large volumes, but also for professional cleaning of the well. Among their advantages is the ability to work with large volumes of water, not only clean, but also quite contaminated. Drainage pumps can process tens of cubic meters of water in one hour. For comparison - submersible centrifugal household pump will be able to provide “only” 3-4 cubic meters.

It also provides special protection against dry start-up. It can be implemented as a traditional float system, and using electronic fuses.
But the system also has its drawbacks. In particular, this is not a very high height to which the drainage pump can supply water - up to ten meters.
How to install a submersible pump yourself
Installation work in the case of a submersible pump looks quite simple; almost every consumer can do it. To do this, you will need to perform the following simple manipulations:
Correctly installed submersible pump.
- Secure the pump itself with a strong cable;
- Lower the pump into the well. As for the depth, experts advise ensuring such a immersion depth that there is at least 30 centimeters between the pump and the bottom of the well;
- The pump itself should also not touch the walls of the well. This requirement is especially critical for vibration pumps. Indeed, as a result of constant vibrations, the body of the device will hit the walls of the well and very soon break;
- Now you can connect the pump to the network.
As you can see, everything is quite simple.
What characteristics should you pay attention to when purchasing a pump?
First of all, its power. This parameter will also determine the performance of the device. Here you should focus on your own needs. For comparison: a pump with a power of 200 - 300 watts can supply up to 18 liters of water per minute, but models with a power of up to 600 watts can supply 55 liters in one minute.
Working depth. Here you need to focus on the depth of the well itself. As a rule, 8 meters is quite enough. However, there are models of well pumps that can operate at a depth of up to 30 meters, but these are quite expensive.
Finally, knowing the distance between the well and the consumer point, you can calculate the required water supply height. Professionals advise when choosing a particular well pump model to take into account a reserve of about a third. In this case, even in the event of unforeseen situations, you can not reduce productivity.
From the point of view of specialists
Oleg Stepanovich Zavadsky, pumping equipment adjuster: The optimal solution when lowering the pump into the well is the use of a metal cable with anti-corrosion coating. You can also use a more inexpensive, but also less durable option - nylon cords.
Sergey Semenov, sales consultant: Do not rush to try the submersible pump in action right out of the box immediately after returning from the store. After all, if you turn on the pump, as they say, “dry,” you can almost guarantee that it will be damaged.
Results
If we try to summarize what has been said, we can safely recommend submersible wells to the widest range of consumers. You need to choose a model carefully, based on your needs and specific operating conditions.
Security country house water is probably always the primary task when creating, even if not comfortable, but simply acceptable, minimal necessary conditions even temporary residence in it. Well, if the house is considered as the main place of residence of the family throughout the year, then the presence of a constantly and stably operating source of water generally becomes a prime necessity. Conventional water supply networks in suburban villages are not found everywhere, so you often have to rely on autonomous sources.
Often the only possible source on a site becomes a traditional well, and the owners are left to organize the transportation of water from it to the points of consumption. A rocker with buckets on the shoulders of a slender housewife is very beautiful in pictures and in feature films about peasant life, but completely divorced from current reality. Modern homeowners come to the aid of a variety of pumping equipment that can solve their water supply problems. In this publication, the emphasis will be on how to choose the right submersible pump for a well, so that the household’s need for clean water for a variety of needs is fully met.
Advantages of submersible well pumps
Providing the house with water from a nearby well can be done using a surface pumping station or a submersible pump. Both options have their own advantages and disadvantages, which should definitely be taken into account when developing a housing water supply scheme. In this publication, let’s take surface-type equipment out of the equation and talk only about submersible equipment.
One of the solutions to the water supply issue is a stationary pumping station
submersible pump
If country house is permanent place residence, if there is an isolated noise-proof room, if the parameters of the well meet certain requirements, then the pumping station can become optimal solution water supply issue. However, it is obvious that there are too many “ifs”, and in order not to make a mistake, read the information posted in the special publication of our portal.
Why in some cases is it the submersible pump that becomes optimal choice?
- They are almost always limited in the depth of water suction - usually this value lies within 7 ÷ 8 meters. If we add to this horizontal section pipeline from the well to the station itself, then the actual depth may be even less. This often forces one to incur additional expenses to create and equip a caisson for a pumping station in the immediate vicinity of the well. With submersible pumps this is not a problem.
- Submersible well pumps, unlike surface ones, will not annoy owners with noise during operation.
- Submersible well pumps are always less “capricious” in terms of the quality of the pumped water - most of them are able to cope with fine suspensions, which are very likely in well conditions.
- If the flow of the water source is sufficient, the risk of overheating the pump drive is minimal - it is constantly in a cool water environment and is additionally cooled by the pumped flow.
- With submersible pumps, it is easier to organize monitoring of the water level in the well - special float automatics installed on many modern models, will take it upon himself.
- The use of surface pumping stations imposes special requirements to the tightness of the water intake pipe. The slightest leak in the connections, completely invisible to the eye, will inevitably lead to air leaks. By definition, a submersible pump has nowhere to suck air from.
- If there is a need to leave your home unattended for a long period, then removing and removing the submersible pump will be easier than, for example, dismantling pumping station from a caisson or a room allocated to it.
