  • A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler.The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.

  • Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps. The design of boiler feed pumps regarding

  • Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of FWP is their high differential head. In medium to large size coal- and oil-fired power plants, the main FWP are horizontal barrel type while booster pumps are horizontal single stage double suction type.
