Boiler Feed Pumps

What is a boiler feed pump?

A pump that controls the amount of water that enters a boiler and the way in which the water is fed. They’re particularly useful in high pressure boilers, such as water tube boilers used in industrial applications, and those that generate superheated steam. In general, because most boilers work exclusively with water, these pumps don’t need to be equipped to handle heavier or more volatile fluids. They merely need to be able to accelerate the water and to control the flow at set rates.

How do they work?

Because there are many types of boilers used in all kinds of residential and industrial applications, there are a number of possible pumping mechanisms and configurations. Most boiler feed pumps are centrifugal pumps, with the majority or these being multistate pumps. And because many boilers require very specific and adjustable rates of flow, some also must have their flow controlled by some sort of flow control system. This allows the operators of the industrial facility to regulate the amount of heat and pressure that is created by the boiler.

Other related Pump Types include: water pumps, high pressure pumps.
