Centrifugal Monoblock Pump sets 1440 RPM

OSWAL Centrifugal Monoblock Pump Sets 1440 RPM with optimum suction lift characteristic is in huge demand in the market for its extensive hydraulic efficiency. We have equipped these pump sets with advanced impellers, ball bearing, and seals that augment the life of the product. OSWAL Centrifugal Monoblock Pumps confirm to IS: 9079 and powered by fan cooled AC induction motor ideal for consistent performance. We have used premium grade low watt loss steel laminations to fabricate motor stator that promises consistent, noiseless, and vibration free operation. Moreover, the OSWAL Centrifugal Monoblock Pump Sets are varnish impregnated windings designed and developed from copper wire. Herein, the pump shaft is suitable for transmission of rated Horsepower.
