What is a Submersible Pump?
A submersible pump is a centrifugal pump that can be submerged in water to work, transporting fluids below the liquid surface to above. Submersible pumps have sealed motors to prevent water from entering. They are more efficient than regular pumps, and the liquid flowing around the motor continuously cools the pump to ensure maximum efficiency.
How Does a Submersible Pump Work?
Motor Drive Process
The magnetic field generated by the energized motor causes the motor rotor to rotate, and in this process, electrical energy is converted into mechanical energy. The mechanical energy transmits energy to the impeller through the pump shaft, causing the impeller to rotate.
Water Intake Process
The motor drives the impeller to rotate, firstly, the curved design impeller sucks the liquid into the center of the impeller by rotating, immediately after the water in the center of the impeller is thrown to the surroundings, in this process, the centrifugal force generated by the impeller is the key factor in the whole operation process of the submersible pump.
Pressurization Process
With the impeller constantly rotating to generate centrifugal force in the process, the liquid is accelerated to the impeller around, high-speed movement of the liquid in the gradually narrowing the flow channel to accumulate and wait for discharge, at this time, the pressure of the liquid gradually increased.
Process of Elimination
The pressurized liquid flows through the flow channel, the narrowing of the flow channel and the smaller pump outlet opening further increase the pressure of the liquid and eventually the liquid is discharged at the pump outlet under high pressure.
Process of Water Circulation
Continuous water intake and drainage by the submersible pump creates a continuous water flow movement. This continuous and stable water flow ensures that the project can be completed efficiently.
Conclusions
Through the motor to generate kinetic energy to make the impeller rotation, the impeller centrifugal force of the role of the liquid is sucked in, and high speed, high pressure liquid discharge, the whole continuous operation of the entire system to produce water circulation, stable, efficient submersible pump is the key to the fluid transfer system.

Main Parts of a Submersible Pump
Pump casing: The pump casing is the container that holds the individual pump components, and is generally manufactured from high chrome alloy.
Motor: The motor of the submersible pump is sealed to prevent water from entering and can operate completely under water.
Pump Shaft: The main function of the pump shaft is to connect the motor to the impeller, transmit power from the motor, and support the impeller in rotation.
Impeller: The impeller sucks in and discharges liquid mainly by rotating.
