FAQ's

What is the difference between a boiler feed pump and a boiler feed unit?
  • Boiler Feed Pump: A standalone high-pressure pump that sends feedwater directly into the boiler.
  • Boiler Feed Unit: A complete system with a tank + pump(s), used where storage volume and staged pumping are required.

How do I size a boiler feed pump?

Match the pump’s TDH (total dynamic head) to the boiler’s operating pressure plus piping/friction losses. Our team can size this for you.

When do I need a boiler feed tank?

Any system with fluctuating steam load, multiple boilers, or high condensate temperature typically requires a storage tank.

Can these pumps handle condensate return?

Yes — many boiler feed pumps are built to handle hot condensate, and we also offer dedicated condensate return units.

What materials are available?

Steel, stainless steel, and Corten steel tanks; stainless or silicon-brass impellers; John Crane mechanical seals; square D controls.
