Construction, operation and application of submersible pumps

A deep well pump is an automated device used to quickly draw water from its own intake, mainly from drilled wells. It is used in home gardens, multi-family farms, allotments, farms and in industry. It is made of a suction part and a pressure part on two sides. When the pressure in the hydrophore tank drops below a certain value, the pressure switch will supply power to the engine and cut it off after reaching the appropriate pressure. The engine-driven impeller creates a pressure difference between the two sides, which causes water to be pumped. The water pushed out goes to the receiver, e.g. a hydrophore tank, sprinkler, etc. A deep well pump also consists of other parts, such as a check valve, housings, seals and bearings. Models designed for large installations have a three-phase electric motor.

Why is it worth investing in a submersible pump?

With a submersible pump in your well, you ensure an uninterrupted supply of water for use in a variety of applications. Water can be efficiently pumped from a depth of several hundred meters! New generation submersible pumps offer high efficiency and economical, trouble-free operation for many years. A good submersible pump can serve you for up to a dozen years.

Selecting a submersible pump for a well

A deep well pump should be adapted to the specifics of a given intake, therefore, when selecting it, you should pay attention to such aspects as:

• well efficiency,
• expected amount of water to be pumped,
• static and dynamic water surface,
• water purity,
• type of receiver,
• water treatment method,
• pump diameter / borehole size (the pump must move freely in the well borehole).

The quality of the deep well pump is of great importance. The design should be equipped with a housing that is completely resistant to corrosion. The manufacturer's reputation speaks volumes about the robustness of the solution. It is worth knowing that the engine power is not crucial for the efficiency of the deep well pump. Buying a pump that is properly matched to the well is one thing. Then it must be connected correctly, i.e. armed and lowered towards the bottom of the well. To prevent dangerous dry running, the discharge nozzle must be at least 2 meters below the lowest water level.
