Boiler Feed Pumps

Finding the right boiler feed pump and boiler water feed system is important — it's an essential part of boiler systems. Identifying the one you need can be hard, as not all of them are equal in quality. To maximize the capabilities of your boiler feed system, it is crucial to find the right parts to assemble. One of the main considerations when choosing a pump is making sure it can overcome the pressure in the boiler.


What Do Boiler Feed Water Pumps Do?


The main purpose of boilers is to produce steam, and a feed pump brings in more water that will replace the lost or used steam. These pumps withstand high inlet pressures and generate large differential pressures. Steam produced in a boiler can have many jobs, such as heating homes, heating water, power generation, sanitation and many other applications. Boiler systems are elaborate machines that begin their process with feedwater entering the boiler system, which is why a boiler feed pump is also crucial. It is either feedwater, condensate returns or a combination of the two that gets pumped into the system.

The boiler designer calculates the operating parameters such as:

  • Flow

  • Head

  • Temperature

By preventing lower water levels, feed water pumps help avoid potential damage to the boiler from overheating or other issues related to insufficient water supply. Proper feed management helps maintain the boiler's thermal efficiency, reducing fuel consumption and operating costs.


Product Description


We offer many feed pump boiler systems — manufactured by Grundfos — in different sizes to meet your situation, no matter what it may be. Each of our boiler feed water pump systems has passed multiple tests to meet industry standards, making sure each boiler feedwater system we provide is unmatched in quality.

FAQ's

What does a boiler feed pump do?

A boiler feed pump delivers water into a steam or hot water boiler at the required pressure to maintain proper water levels. It replaces water lost through steam consumption and prevents dangerous low-water conditions.

What is the difference between a boiler feed pump and a condensate return pump?

A condensate return pump collects and returns condensed steam back to the boiler, while a boiler feed pump pushes feedwater into the boiler under higher pressure. Many systems combine both functions depending on the application.

How do I size a boiler feed pump?

Sizing is based on three main factors:


  • Flow rate (GPM) needed by the boiler

  • Total head / pressure required to overcome boiler pressure

  • Temperature of the feedwater or condensate Our team can size the correct model based on your boiler specifications.

What type of boiler feed pumps do you carry?

We offer vertical multistage inline pumps and horizontal multistage pumps from Grundfos and Air Flow, available in single-phase and three-phase configurations. Options include 1.25″–4″ flanged discharge and various horsepower ranges.

How fast can boiler feed pumps ship?

Most boiler feed pumps and boiler feed units ship within 24 hours, and pre-assembled packages are available for faster installation.

Do you offer complete boiler feed units?

Yes. We supply complete boiler feed systems with tanks, controls, and multistage pumps.

Boiler Feed Units

Can these pumps be used with both steam and hot water boilers?

Yes. Boiler feed pumps are compatible with steam boilers and high-pressure hot water systems, as long as the pump selected meets the required pressure and temperature specifications.
