250S39 pumps are double suction horizontal split case centrifugal pump, they are single-stage, double suction, horizontally mounted, applied for general water supply, booster service, municipal waterworks, condenser cooling, water circulation, industrial service, building service, chemical plant, power plants etc.
Split case pumps have been specifically engineered to meet the needs and requirements of the oil, gas and process industries. Tough and robust products are required which have proven long term reliability and benefits, enabling them to perform in often arduous operational and environmental conditions - where dependability is of paramount importance.
These two sets of pump are applied in Kenya, aside the Lake Baringo. It is used to transfer the lake water to nearby waterworks. Which could greatly help the local residents for daily water supply.
• Advantages:
– Simple operation.
– Low first cost and maintenance.
– Insignificant excessive pressure build up in casing.
– Impeller and shaft are the only moving parts.
– Quiet operations.
– Wide range of pressure, flow and capacities.
– Utilize small floor space in different positions
