Installation of a well pump allows you to organize uninterrupted operation of an autonomous water supply. The choice of equipment requires a study of its technical characteristics and real reviews. The ranking of the best submersible pump models will help determine the appropriate option.
The device and principle of operation of submersible pumps
Owners of private houses with an autonomous water supply system prefer submersible pumps. The choice is justified by the numerous advantages of the units:
- The rise of water to a height of 40-45 m.
- High productivity (6-9 cubic m / h).
- Silent work away from home.
- The drive of the device is in water, reducing the risk of overheating.
- The unit is easily dismantled for conservation in the winter.
The design of the submersible pump depends on the type of motor and the principle of operation. But all models have the main parts: housing, motor, multi-stage pump unit. The engine is located at the bottom of the structure. Above it are blades, the rotation of which sucks water into the equipment. The pressure created pushes the fluid into the pipeline. Vibration models function due to piston movement.
Types of devices
Units of 4 types are suitable for wells:
- vortex;
- screw;
- centrifugal;
- vibrating.
The first two types are rarely used.
Vortex type devices are sensitive to particulate matter in water and are short-lived. Screw pumps give out a stable head, are steady against pollution. Their disadvantage is low productivity.
Centrifugal
The working part of the unit is a wheel with blades. Its rotation provides an electric drive. A powerful centrifugal force arises in the chamber, absorbing and directing the flow of water. Installing multiple rings (multi-stage circuit) increases pump performance. Advantages of the mechanism: quiet operation and the ability to raise liquid to a considerable height. The centrifugal type is considered the best submersible pump for supplying water to the house. This type of units is represented by many models that differ in size and technical characteristics.
Vibrating
Units have vertical execution. In the lower part of the housing there is a coil creating an electromagnetic field. It attracts and repels the anchor with the stock. The action takes place 50 times per second. A vibration is created that gives the name to the mechanism. An elastic membrane and a piston are installed in the upper part. Pulling the anchor causes the membrane to bend. Low pressure is created in the chamber, water enters. After returning to the initial state, the rubber part overlaps the inlet, and the fluid is directed to the outlet. Vibration mechanisms are the most affordable.
Disadvantages: constant vibration leads to the destruction of the well shaft, turbid water.
Key selection criteria
Before purchasing a pump, you should determine its purpose. For watering, a budget vibrating unit is enough. Centrifugal pumps are best placed in a well for water supply of a house with a permanent family residence. When choosing equipment, the following factors are considered:
- head or height of rise of water;
- productivity - the volume of fluid supplied per hour;
- protection against dry running and overheating;
- electrical parameters (power, power);
- dimensions and weight.
Productivity is calculated according to the number of people and average norms of water consumption. The pressure characteristic is selected according to the depth of the well and the length of the pipeline.Built-in dry running protection will shut off the motor in the event of a drop in water level.
Rating of the best submersible well pumps
Aquarius BTsPE 0.5-50U

The pump can operate in a plumbing system with a hydraulic accumulator or in manual mode.
Livhydromash Kid-M BV 0.12-40
Household vibrating pump with top water intake. It can be used to pump water from the basement during flooding. Raises liquid 40 m.
Pros:
- little weight;
- continuous operation without engine overheating;
- affordable cost;
- no power consumption.
Minus: shallow dive depth.
Unlike many models of vibration units, the Kid works quietly.
Grundfos SBA 3-45 A
The model is designed to pump water from wells and open reservoirs. Immersion depth 10 m. The unit is equipped with a strainer and a float switch. It works automatically as protection against dry running. Head 30 m, water supply 3 cubic meters. m per hour.
Advantages:
- silent work;
- reliable engine protection;
- high power
- due to quality assembly, it rarely breaks.
Less: for normal operation requires the installation of a hydraulic accumulator.
Grundfos products are considered one of the best submersible pumps for supplying water to a house from a well. They are resistant to small power surges.
Dab diverton 1200
The submersible pump is equipped with electronic on and off control. For the effective operation of the water supply, no installation of the storage tank is required. Productivity of the model is 5.7 cubic meters. m / h, the height of the water rise is 48 m. The device is immersed at 12 m.
Advantages:
- installed protection against dry running and overheating of the motor;
- unit operation is automated;
- excellent build quality;
- high power.
Minus: water supply delay up to 2 sec.
The performance of the device allows you to provide water to a family of 5-7 people. In the Top of the Best Models, the Dab Diverton 1200 is in first place.
Gileks Vodomet 150/45 A
The model is designed to supply clean water from the well. Its performance is 9 cubic meters. m / h, head - 45 m. The unit is equipped with a float switch. The type of mechanism is centrifugal. Stainless steel case.
Advantages:
- increased pressure characteristic;
- the presence of thermal relay;
- long period of operation.
Minus: for reliable operation, a connection to a current stabilizer is required.
The unit can be lowered to a depth of 30 meters.
Gardena 6000/5 Comfort
The submersible pump is designed for a depth of up to 12 m. Its capacity is 6000 l / h, the lifting height is up to 45 m. The flow sensor provides switching on. The model is equipped with a check valve, which reduces the period of water absorption during restart.

Reviews of choosing pumps for a well
Before buying a suitable model, its main characteristics are clarified: power, immersion depth and head height.One of the modern ways of orientation in goods is to study reviews on the choice of a submersible pump for wells. Consumer experience helps to learn about the disadvantages and advantages of units. Among automated pumps, the best was the Dab Divertron 1200. It allows you to ensure stable operation of the system without a hydraulic accumulator. Customers note the high quality of Gardena products, but not every family budget can afford them.
Installing a submersible pump eliminates the difficulty of supplying water to the house and to the place of irrigation. When choosing a model, you should pay attention to the warranty period and the availability of a network of manufacturer service centers in the city.
