Section I of the ASME Code contains rules for Power Boilers which, for the case of steam boilers, are boilers designed for a maximum allowable operating pressure (MAWP) greater than 15 psig.
The feed pump raises the feedwater to a pressure high enough for it to enter the boiler. For auxiliary boilers, where small amounts of feedwater are pumped, a steam-driven reciprocating positive displacement pump may be used. Another type of feed pump often used on package boiler installations is known as an 'electro feeder'.
