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.

Dec 08, 2017 · Boiler feed booster pumps are generally BB1 or BB2 configuration (see Figure 3.9) that have single-stage, double suction design and operate typically at four-pole motor speeds. The double suction impeller and low speed reduce the NPSHR of this pump type to suite the system design.

Feb 17, 2021 · End-suction pumps are actually single-suction pumps. Both end-suction centrifugal pumps and double-suction centrifugal pumps are similar, with similar advantages and disadvantages. The only difference between the two is: the water inlet on the impeller side is end-suction (single suction), and the two Side water is called double suction.
