202033 · Centrifugal Pump. The pumps consist of two main parts, the pump and the motor. The motor is an electrical induction motor which allows us to convert electrical energy into mechanical energy. This mechanical energy is used to drive the pump and move the water. The pump pulls water in through the inlet and pushes it out through the outlet.
