Boiler Feed Units

Boiler feed units store condensate and makeup water and deliver it to the boiler on demand at the pressure and temperature your system requires, protecting the boiler from low-water conditions and thermal shock. ePumps carries boiler feed pumps and complete feedwater units in simplex and duplex configurations, with receiver tanks sized to your feed rate and pumps rated for high-temperature boiler feed service. A properly sized boiler feed system smooths out condensate return surges, maintains a steady boiler water level, and reduces cycling on the feedwater valve, which extends boiler life and improves efficiency. Typical applications include steam heating and process-steam plants, hospitals, schools and universities, food and beverage processing, and industrial facilities running low- and high-pressure boilers. New to feedwater sizing? Read what is a boiler feed system for the basics. Select a unit by receiver capacity, pump horsepower, discharge pressure, voltage, and simplex or duplex operation below. Duplex boiler feed units add a standby pump and alternating operation for continuous-duty reliability. Not sure how to match feedwater capacity and pump pressure to your boiler? Our team will help you size the right boiler feed pump and receiver for your load.

FAQ's

What’s the difference between a boiler feed pump and a boiler feed unit?

A pump is just the pressure-rated pump itself. A boiler feed unit includes the receiver tank, controls, and one or more pumps as a complete packaged system.

How do I choose the right tank size?

Most systems use 1 minute of net boiler output as standard tank sizing. Larger boilers or higher demand may require 2–3 minutes of storage.

Can boiler feed units handle both condensate and makeup water?

Yes. They store condensate and automatically add makeup water when levels drop.

Do units come fully assembled?

Yes. ePumps offers pre-assembled units with pumps and controls mounted and wired for quick installation.

Which pump type is used in feed units?

High-pressure multistage pumps, typically Grundfos CR/CRI series, to overcome boiler operating pressure.
