When it comes to function and performance, boiler feed pumps can take your pumping applications to the next level. Curious about what a boiler feed pump is and what role it serves in the boiler system? You’ve come to the right place.

To help you find the boiler water treatment system that’s right for you, here’s everything you need to know about the different boiler feed pump types, their operation, and more!

Boiler Feedwater Systems: What You Need to Know About the Role of the Feed Pump in Boiler Applications

How does a boiler feed pump work? Simply put, they are multi-stage pumps that pump water into a boiler, whether it’s new water being supplied or condensate returning to the boiler system. Boiler feed water pumps ensure the boiler has the right amount of water to operate effectively, efficiently, and safely.

Boiler feed pumps are often versatile in how they operate within the boiler system. They tend to consist of multiple impellers between bearings that work to generate the high pressure required to feed the boiler correctly.

Types of Boiler Feed Pumps

Selecting the correct type of pump is essential for any application – and boiler feed water pumps are certainly not one-size-fits-all. Various types of pumps are available, differing in how they operate and the type of pressure they can handle.

For instance, the most common types of feed water pumps are centrifugal pumps, horizontal pumps, and vertical pumps. All have their share of pros and cons. For instance, horizontal pumps are easy to access and, thereby, more straightforward to install, remove, and maintain. Vertical pumps don’t take up a lot of floor space, making them ideal for use when space is limited, but they do require vertical space to operate. Because of their vertical nature, they’re often more difficult to maintain over time. Centrifugal pumps are known for their reliable performance.

Factors When Selecting a Boiler Feed Water Pump

So, what factors should you consider when choosing a feed water pump? Space is one key consideration, and it’s where the selection of a horizontal or a vertical pump can make sense. Other factors to consider include:

  • The amount of pressure required. It’s imperative to know whether the pump you’re eyeing can successfully overcome the pressure within the boiler system.
  • Feed pumps also have to handle the temperature requirements of the boiler system in addition to pressure.
  • The material. Feed pumps are typically made from either bronze or stainless steel. Consider any of the chemical additives that are included in the water the pump is going to be feeding to gauge any potential reaction with the material.
  • Other factors. A few other factors to consider include flow rate, pump efficiency and reliability, and maintenance requirements.


Boiler feed pumps are essential in any industry that utilizes a boiler, from heavy-duty industrial applications to commercial and residential applications.
