Quality and reliability
  Country Russia
Average price: 26 000 rub.
Rating (2017): 4.5

One of the best selling submersible pumps for the well. GILEX Vodomet PROF 55/75 - the second place in the rating. Most homeowners purchase GILEX Vodomet because of the availability of services and spare parts, although the device is one of the most reliable among well submersible pumps.

Due to the high humidity in the wells, the use of a rigid suspension with bolts and nuts is undesirable due to the complex disassembly and rapid corrosion of the fasteners. Observe the installation and operating instructions of the manufacturer! Use a suction tube with a diameter greater than or equal to the diameter of the pump inlet.

Varieties of well pumps

From the suction pump to the pump, the suction line has no spin and siphons that are difficult to pump. The suction cup has a mesh of at least 0.4 mm. Using a network with smaller openings and additional nets makes the pump more difficult, increasing the risk of clogging.

This is a self-contained system, equipped with everything necessary, including protection against dry running and overloads. Water cannon PROF 55/75 has a capacity of 3.3 cubic meters. m / hour and according to numerous user reviews, it holds water pressure perfectly.

The resource of the water pump is increased due to the lower speed. Using the control panel and the pressure sensor, you can program the operation mode of the device and protect it from dry running and voltage surges.

Suction must be installed at a distance of at least 20 cm from the bottom and from the side walls of the pool. To change the suction at the end of the suction pipe, install a throttle. In the case of water supply systems with running water, sand, you can use, if possible, a system of intermediate settlers and overflows to limit entrainment of particles in the suction zone. Settlers should be regularly cleaned of sand covered by them.

Rating of the best submersible drainage pumps

Suction connections must be made using solder or threaded seals. The use of quick couplings with polyethylene pipes and flexible reinforced inlet pipes is undesirable because of the danger of overpressure. The least unhealthy condition on the suction side of the pump can lead to a change in pump parameters, including disconnection.

Small “semi-welded” pumps for flooded basements and irrigation

In areas with very hard water and mechanical impurities, the suction return valve is replaced prophylactically every two years. You are looking for a pump for your specific purpose, but can you choose all the parameters and the different types? The best choice is to choose the pump depending on what you will use, because the choice is important in terms of its life. These pumps are used for pumping water, for example, from barrels, rivers, cellars and similar sources, for irrigation, etc. pumps from this group are not characterized by high flow or discharge. However, slightly contaminated water containing small solid parts can be held with them. Pumps are usually equipped with a float switch to ensure that the pump shuts off in case of water shortage. Pumps are cheap and their price depends on the type of material the pump is made of. Pump pumps suitable for a septic tank or septic tank or for heavily contaminated water. Some of them are also equipped with a cutting device that can turn a very dense liquid into a pumpable state. Optionally, they are equipped with a float switch that turns off the pump after draining the liquid.

Well pump for feeding and pumping from high depths

  We also recommend powerful “spindles” that have a longer service life than a rotary pump with an internal propeller. You can also purchase a pump only for transporting water from a deep well. Although water is not under pressure, but when it is combined with an increase in mini-hydrogen pressure, it becomes cheaper than buying a submersible pump under pressure.

Horizontal pumps are the best option for landscaping gardening

  They are characterized by high pressure, high flow and relatively low cost. They are best suited for connecting to garden sprinklers, sprayers, etc. these are self-priming pumps. This means that there is no need to pump the pipeline several times, the pump can process the water "pull" itself. These pumps can be equipped with a switch and an inexpensive horizontal pump. However, its performance is sufficient to run three surface sprayers and water of several tens of square meters.
  • These pumps are designed for very heavily contaminated water.
  • Usually they are made of cast iron.
  • Interesting, for example.
  • This is a vibrating submersible pump.
  • It is one of the smallest and cheapest horizontal pumps on the market.
Most people still do not know that a pump is not a pump.

The throughput of 0.5-0U BTsPE is 3.6 cubic meters. m / h - such productivity is enough to provide a family of 3 to 4 people. There is enough water pressure for the kitchen, shower, and even for watering.

In TOP-3 Aquarius BTsPE 0.5-50U is considered the most powerful and at the same time the most inexpensive submersible pump. So, we can safely call this model one of the best in terms of price and performance.

To choose the right option, to satisfy your ideas and do the right job, you first need to clarify what you really expect from it. And since technical assistance is often needed by a typical layman when choosing it, you should always buy a pump only at specialized gardening stores. You just can be sure that you accept the right things in terms of user requirements in terms of running costs and life.

The main criteria for choosing a pump. The purity of the pumped liquid - it is important that only crystal clear water, slightly dehydrated water or moist water with possible impurities. Where you will draw water \u003d required pressure at the outlet of the pumped liquid - you need to know whether it is a well or a well, how deep the water is and how the water source is supplied.

Rating of the best submersible pumps for a well

Water pumps for a well (well) are installed to draw water from a depth of 7 to 50 meters. Most models are made of steel and are designed to pump clean water. The recommended distance from the bottom of the reservoir is 1 meter. A distinctive feature of the design of well pumps is the location of the water inlet in the lower part of the housing. This allows you to operate the water pump even when partially immersed in water. Unlike well pumps, well pumps at lower cost give greater productivity. Although, in terms of the maximum height of the water column, they are still inferior to the models designed for wells.

What you need is a flow - don't underestimate the quantities you want to draw. Requiring surgery - specify whether the pump will be used for casual use, for example, in the garden or in a permanent place, for example, to supply the house with all the water.

A small overview of well pumps

Garden electric and gas pumps. Pumps with an electric garden are divided into surface and submersible. It is especially suitable for autonomous water supply from cold water, ponds, lakes and reservoirs. The basic design of the garden pump should be made of non-aggressive materials such as stainless steel, cast iron or high-quality plastics. Modern plastics can be matched with the strength of metals. Stainless steel and plastic also resist scale formation. The ground pump includes a flexible spiral suction hose to avoid pressure suction.

3 Technopribor Brook-Technopribor 1

Best price. Cheapest well water pump
  Country Russia
Average price: 1603 rub.
Rating (2017): 4.0

Of course, for the money you should not expect high performance. The brook is able to pump only 1.05 cubic meters. m / h at a diving depth of up to 60 m (far from a low indicator). They buy such a device for one task - installation in a well. Some users install the pump in storage drums for watering the garden. Due to the vibration mechanism, the pump makes a lot of noise (which users complain about), but at low power, good throughput is ensured.

In the end, it has a suction cup with a non-return valve and sometimes with a filter. These pumps are portable and can be used in many ways. For easy installation, the electric pump must be equipped with a power cable. Self-priming pumps are easiest to operate.

Submersible pumps, as the name implies, are immersed in the pumped water and are designed to pump water at great depths and great distances. Therefore, choosing them, you must be interested in the high quality of the materials used and the proposed warranty. It may also be 7 years old for better equipment. They are used, for example, to supply residential buildings, as well as for irrigation of gardens.

"Brook" is a fairly reliable and unpretentious water pump. Although, for that kind of money, worrying about reliability is not entirely correct. In extreme cases, you can buy a second trickle, because no competitor offers such a low price.

User review:

People, this is not a pump to kill. I already bought myself the second one. For 3.5 years of tough operation, the trickle lost only 20% in productivity. High noise, this is of course a minus, but what else to expect from the device for 1500 rubles ...

They are used to empty water tanks or as drainage pumps from swamps and ponds and even cesspools from the cavity. Or also during the discharge of flood water, for example, from cellars. These pumps do not mind that there are impurities, sludges and stones with a size of 5 mm in the pumped liquid, for special pumps with a size of 30 mm. They have a relatively small discharge height, but a large throughput of up to 350 liters of wastewater per minute. The use of durable materials such as traditional gray cast iron, stainless steel housing and high-quality mechanical seals ensure a long service life even under extreme operating conditions.

Low-flow pump for a low flow rate well

Slurry pumps are flexible, can be used for continuous operation in mines and wells, for portable use and a wide range of applications. In general, water pumps with clean water pumps that have a high solids flow rate can be used to pump process water and clean water. However, it is never possible to use a submersible pump designed to pump clean or service water to pump sludge.

At a relatively low cost, the device is equipped with a thermal protector with temperature response (protection against overheating) and protection against dry running with a float switch. The case is made of stainless steel.

In their reviews, users note the following advantages of JILEX Vodomet PROF 55/50 A:

  • Nimble work
  • Noiselessness
  • 20 meter cable included
  • Dry run protection
  • Ease of installation

Disadvantages:

Smaller types of submersible pumps have a suction port located so low that the float switch automatically trips until the submerged tank in the tank drops to 3-5 mm. Some of them drain water up to 1 mm, so the rest just wipe the rag. Therefore, when choosing a submersible pump, you should pay particular attention to the minimum level. Of great importance is the value of maximum impurities in water.

The main types of pumps and their features

The submersible pump must be equipped with a float switch, a thermal fuse, a sufficiently long electric cable and a connection for connecting hoses of various sizes. They will find application wherever water will stretch from the deep depths. Piston well pumps have an elongated cigar shape and are very compact and reliable machines that can withstand continuous operation. Their work, which takes place under water and at great depths, is almost silent. Each submersible pump must have high-quality mechanical seals and housing cooling to ensure trouble-free operation.

Private houses remote from the city are most often not connected to the water supply system. The only way out in this situation is the arrangement of a well or well. But for water to enter the house, a pump installation is necessary. By design, they can be submersible and superficial, but each of them has its own advantages and disadvantages. Therefore, it is extremely important to know which pump is best for the well to choose.

Surface devices are designed for wells and boreholes with shallow depth. To the surface of the water should not be more than 8-9 m. For wells with greater depth, submersible pumps are installed, so they are also called deep ones in another way.

Surface devices are placed outside the well. Thanks to what they are easy and convenient to serve. Often they are installed together with an accumulating tank to stabilize the pressure in the system. But because the surface pump works outside the well, it makes a lot of noise and also takes up space. As a result, it is necessary to equip an area for it and build a building to absorb sounds. Since the pump is out of the water, its motor is not cooled by it.

The layout of the internal and external pumps for the well

Submersible devices are divided into several types:

  • vortex;
  • screw;
  • vibrating;
  • centrifugal.

Vortex pumps have one impeller. It draws water into the inside and pushes into the outside, due to which a vortex appears. As water passes through the wheel, its speed and pressure increase. The design of these pumps is simple, so they have a low price. But because of this, they have low efficiency and are unable to work with liquids in which there is sand or other similar impurities, as this leads to rapid wear of the device.


Vortex pump device

The main working element of a screw device is a screw (auger). Water getting inside the pump is gradually pumped by the screw, as a result, pressure appears and the liquid is forced out. As well as a vortex device, the screw has a simple design and a low price. Recommended for use in wells with low flow rate. But compared to a vortex pump, a screw pump is more resistant to impurities in water.

The scheme of the screw pump

Vibrating or centrifugal

The vibration device is capable of pumping water from wells up to 40 m deep. They have a simple design and a relatively low price. The vibration pump does not require constant maintenance, and has a small weight and dimensions. But he is unable to work for a long time, and can also give out not enough strong pressure. The main drawback is that due to vibration, the walls of the well are destroyed, and it gradually falls asleep.


The scheme of the vibrating pump

A centrifugal pump, unlike a vibration pump, works without damage to the walls of the well and does not make noise. There is also a large selection of devices of this type with different characteristics.

The impeller of a centrifugal pump consists of a front and rear discs, and between them there are blades directed in the opposite direction of its movement. It is on the number of these wheels that the pressure head depends, the more there are, the higher it is. Therefore, centrifugal pumps have different heights.

Note! Unlike all previous devices, centrifugal pumps are able to work for a long time, and they are also more energy efficient.
