The Working Principle of A Submersible Pump

The working principle of a submersible pump is as follows:


  1. Motor drive: Submersible pumps usually use an electric motor as the power source. The motor converts the electrical energy provided by the power supply into mechanical energy, driving the impeller inside the pump to rotate.

  2. Impeller rotation: The impeller inside the pump is connected to the motor shaft. When the motor starts, the impeller begins to rotate. The impeller typically has grooves or blades that generate centrifugal force when rotating.

  3. Liquid suction: The rotation of the impeller generates centrifugal force, causing the liquid to be drawn into the pump through the inlet. The pump body is typically designed with a sealed structure to prevent water from entering the motor section.

  4. Liquid discharge: The suctioned liquid passes through the internal flow channels or pipes in the pump body and is compressed, and then discharged through the outlet. The outlet is usually connected to a piping system to transport the liquid to the desired drainage location.

The working principle of a submersible pump is based on centrifugal force and the pressure difference of the liquid. The centrifugal force generated by the rotating impeller draws the liquid in and pushes it out of the pump body. This working principle makes submersible pumps highly effective in handling deep water or applications that require long-distance liquid transportation.
