Coimbatore-based eureka pumps offers submersible pumps of extreme wear resistance property. The pump casing is made of high-grade cast iron with special anti-corrosive treatment. The impellers are dynamically balanced and made of graded bronze. The pump suction unit is protected by a strong brass strainer that prevents entry of suspended materials into the impeller. Since the motor and the pump are water lubricated, no lubrication is required. Some of the key features are as follows: - range: from 2 hp to 60hp -rotor shaft made from nickel-chromium rod and the solid rotor treated with epoxy for a dynamic balance -sleeve bearings made of zinc free bronze have good wear resistance property -motor shaft fitted with rubber oil seals and sand prevents entry of borewell water that contains sand and impurities -highly corrosion resistant studs and nuts made from non-magnetic stainless steel.
