Abstracts: Submersible pump is centrifugal type of pump which pumps out water from the bored hole or well. The pump is coupled with an electric motor. The shape of the pump and Motor is cylindrical which makes it easy to be fitted in drilled bore in the earth. The Pump remains dipped in water due to which there will not be any suction trouble. Submersible pump is used for continuous discharge of water in quantity as well as for High heads. But after long time of suction from earth the water surface getting lower from its initial surface which causes the dry run of pump which effect the winding of motor. That prevent by thermal relay provide into the circuit box of pump. Also there are many dust particles streamed into the earth water such as lime, sand, dust etc. Which try to come into the pump through the filter at suction, which prevent by providing wire mesh filters at the suction of the pump that did not effect the head of the pump. By using CFR rotor in motor rotor the head get into the pump is lower after consumption high power which is solved by using DCR rotor. That consumes less electricity compare to CFR rotor and gives higher head as output.
