How to choose a submersible pump to supply water to a house from a well

Installing a well pump allows you to organize the uninterrupted operation of an autonomous water supply system. The choice of equipment requires a study of its technical characteristics and real feedback. A rating of the best models of submersible pumps will help determine the right 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 meters per hour).
• Quiet work away from home.
• The drive of the device is in the water, reducing the risk of overheating.
• The unit can be easily dismantled for winter storage.

The design of a submersible pump depends on the type of engine and the principle of operation. But all models have basic parts: body, motor, multistage pumping unit. The engine is located at the bottom of the structure. Above it there are blades, the rotation of which sucks water into the equipment. The generated pressure pushes the liquid into the pipeline. Vibrating models function due to the movement of the piston.

Types of devices

Aggregates of 4 types are suitable for wells:

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

The first two are rarely used.

Vortex-type devices are sensitive to solid particles in water and are short-lived. The screw pumps provide a stable head and are resistant to pollution. Their disadvantage is low productivity.

Centrifugal

The working part of the unit is a wheel with blades. Its rotation is provided by an electric drive. A powerful centrifugal force is generated in the chamber, sucking in and directing the flow of water. The installation of several rings (multi-stage scheme) increases the 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 a home. This type of units is represented by many models that differ in size and technical characteristics.

Vibrating

The units are of vertical design. A coil is installed in the lower part of the housing, which creates an electromagnetic field. It attracts and repels the armature with the rod. The action takes place 50 times per second. A vibration is created, which gives the name to the mechanism. An elastic diaphragm and a piston are installed in the upper part. Pulling on the anchor causes the membrane to flex. A low pressure is created in the chamber, water enters. After returning to its original state, the rubber part closes the inlet and the liquid is directed to the outlet. Vibration mechanisms are the most affordable.

Disadvantages: constant vibration leads to the destruction of the well shaft, cloudy water.

Main selection criteria

Before purchasing a pump, you should decide on its purpose. For irrigation, a budget vibrating unit is sufficient. It is better to put centrifugal pumps in a well for water supply of a house with a permanent residence of a family. When choosing equipment, the following factors are taken into account:

• head or height of water rise;
• productivity - the volume of liquid supplied per hour;
• dry running and overheating protection;
• electrical parameters (power, power);
• dimensions and weight.

The performance of the equipment is calculated by the number of people and the average rates 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 ensures that the motor is shut off in the event of a drop in the water level.

Rating of the best submersible well pumps

Aquarius BTsPE 0.5-50U

Versatile model, suitable for wells and wells. The unit is of a centrifugal type, intended for domestic use. Nominal capacity 1800 l / h, head - 50 m. Motor protection is provided by a thermal relay.

Advantages:

• wear-resistant body material;
• high performance;
• the design excludes the ingress of oil into the water;
• long-term operation.

Disadvantage: Sensitive to water quality.

The pump can operate in a water supply system with a hydraulic accumulator or in manual mode.

Livgidromash Malysh-M BV 0.12-40

Household vibration pump with top water intake. It can be used to pump out water from the basement during flooding. Raises liquid up to 40 m.

Pros:

• little weight;
• long-term operation without engine overheating;
• affordable cost;
• no power consumption.

Minus: shallow immersion depth.

Unlike many models of vibration units "Kid" works quietly.

Grundfos SBA 3-45 A

The model is designed for pumping 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 a dry run protection. Head 30 m, water supply 3 cu. m per hour.

Advantages:

• silent work;
• reliable engine protection;
• high power;
• due to high-quality assembly, it rarely breaks.

Minus: for normal operation, the installation of a hydraulic accumulator is required.

Grundfos products are considered one of the best submersible pumps for supplying water to a house from a well. They are resistant to small voltage surges

Dab Diverton 1200

The submersible pump is equipped with electronic on / off control. For the efficient operation of the water supply, the installation of a storage tank is not required. The productivity of the model is 5.7 cu. m / h, water rise - 48 m.The device is immersed at 12 m.

Advantages:

• installed protection against dry running and motor overheating;
• the work of the unit is automated;
• excellent build quality;
• high power.

The performance of the device allows you to provide water for a family of 5-7 people. In the Top of the best models, the Dab Diverton 1200 holds the first positions.

Dzhileks Vodomet 150/45 А

The model is designed to supply clean water from a well. Its productivity is 9 cubic meters. m / h, head - 45 m. The unit is equipped with a float switch. Mechanism type - centrifugal. Stainless steel body.

Advantages:

• increased pressure characteristic;
• the presence of a thermal relay;
• long period of operation.

Negative: connection to a current stabilizer is required for reliable operation.

Reviews on the choice of pumps for a well

Before buying a suitable model, find out its main characteristics: power, immersion depth and head. One of the modern ways to navigate in products is to study reviews on the choice of a submersible pump for wells. Customer experience helps to learn about the disadvantages and advantages of units. Dab Divertron 1200 became the best among automated pumps. It allows to ensure stable operation of the system without a hydraulic accumulator.
