Submersible Pump Test Rig: The designed and developed submersible pump Test Rig is a self-contained unit operated on closed circuit basis containing a sump tank. The set-up consists of a submersible pump coupled with a DC Motor. Power input to the DC Motor is varied by means of a Thruster controlled DC Drive to vary the RPM of motor. A RPM Indicator with Proximity sensor indicates the RPM of Pump. Flow of water is measured by using measuring tank and stopwatch. Vacuum gauge
