These centrifugal pumps are ideally suitable for openwells or tanks where there is a wide fluctuation in water level. This works under water and it rests at bottom of the well. Hence suction and priming problem do not arise. Pump’s volute chamber is designed to give the best possible hydraulic efficiency. Dynamically balanced impeller offers vibration free operation with long life. Prime mover is rewindable, water-cooled motor.

Submersible pumps are designed to function with both pump and motor submerged in the fluid to be pumped. The motor of this centrifugal pump is sealed in a way that prevents liquid from seeping in, protecting against short-outs. Because the motors are below grade, submersible pumps cost less to install and allow for floor space to be better utilized. They also tend to have lower maintenance costs and are less noisy than pumps that have the motor mounted at grade. Since the impeller and casing are always submerged and there is no suction pipe with this pump, there is no concern for priming. Cavitation is also not a worry.
