Horizontal Openwell Submersible Pumps 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. Specially designed water lubricated bearings are used to withstand axial thrust loads with minimum wear and tear. The stator is wound with special water proof synthetic film insulated copper winding wires and made up of low watt loss steel laminations assembled under pressure and rigidly locked in stainless steel stator shell.
Dynamically balanced Rotor gives vibration free and noise free operation, thereby increases efficiency and life cycle of the motor. Motor sealing is made by means of grommets, â„¢ rings, oil seals and sand guard to avoid ingress of well water / sand into the motor. Pressure equalising rubber diaphragm is provided to guard the pressure and volume variation of water inside motor. Motor must be filled with clear, cold, drinking water as detailed in our operatorâ„¢s manual. Three phase motor requires an adequate motor protection control panel.
