BHEL started manufacture of Pumps during the mid-sixties under technical collaboration with M/s Sigma Lutin, Czechoslovakia, to meet the requirements of 60 MW, 110 MW and 210 MW thermal power stations, the scope of which was widened to meet the requirements of power plants upto 500 MW, with the help of another collaboration with M/s Weir Pumps, U.K. BHEL has also made some in-house product development to gain spin off benefits from the above collaboration as well as to develop new pumps to meet the requirements of Combined Cycle Power plants.

BHEL has undertaken a design up-gradation and retrofit of the existing 200 KHI Boiler Feed pumps Inside Stators with energy efficient hydraulics and cartridge design internals under technical tie-up with M/s Sulzer Pumps, Germany; and recommended the upgraded 200 KHI-S Boiler Feed pump to all customers of 110 MW & 210 MW Power Stations operating with the earlier Czech design for increase of pump availability and reliability and also considerable reduction in operational costs.
