6 Facts about Boiler Feed Water Pumps - Empowering Pumps and

 Boiler feed water pumping applications typically require high pressures due to the high temperatures of the feed water. Water changes to a gas state at 212-degrees F in atmospheric pressure. However, boiler feed water ranges are from 225- to 250-degrees F, and some can even reach temperatures as high as 350-degrees F.

CHAPTER 39 BOILER WATER TREATMENT

The pressure and design of a boiler determine the quality of water it requires for steam generation. Municipal or plant water of good quality for domestic use is seldom good enough for boiler feed water. These sources of makeup are nearly always treated to reduce contaminants to acceptable levels; in addition, corrective
