Centrifugal pumps are horizontal end suction.The stage casings are clamped together by external tie-bolts and sealed by gaskets.Pump bearings are enclosed in two-bearings housings which are falnged at each end of the pumps.The pumps are direct driven by electric motor through flexible couplings.The multi-stage centrifugal pumps find use in boiler feed water and condensate hog and cold water circulation fire fighting cooling lowers clean water in chemical and petrochemical industries and in off-shore refineries water supply and sprinkler irrigation schemes high rise buildings and other high pressure applications.
