Sep 15, 2017 · Boiler feedwater pumps should be capable of supplying the boiler with water at a pressure at least 3% higher than that of the drum operating pressure. An evaluation of the line routing from the pump outlet to the drum inlet should be performed and pressure losses calculated to determine the proper discharge pressure.

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
