HVAC & Boiler Pumps

Pumps move water or condensate through hydronic heating systems, boilers, and cooling equipment. A properly functioning pump is important for even heat distribution, system efficiency, and preventing water damage from condensate backup.

Furnace Part Source carries a range of HVAC and boiler pumps, including circulator pumps for hydronic heating loops, condensate pumps for furnaces and air handlers, and related seals, impellers, and mounting components.

Common Pump Parts We Carry

Common pump-related parts include:

  • Circulator pumps for hydronic heating and boiler systems.
  • Condensate pumps for removing condensation from furnaces, air handlers, and mini-split systems.
  • Mechanical seals and impellers for pump service and rebuilds.
  • Pump motors and power assemblies for compressor and pump-driven applications.

How to Find the Right Pump

Before ordering, check the pump nameplate and confirm the model number, GPM (gallons per minute) rating, voltage, and connection size. If replacing a component such as a seal or impeller, match the exact part number to the existing pump model.

For best fit, compare:

  • Original pump part number
  • GPM and head pressure rating
  • Voltage and horsepower
  • Connection size and mounting style
  • System type, such as hydronic heating, boiler, or condensate removal

HVAC Pump FAQs

What is the difference between a circulator pump and a condensate pump?

A circulator pump moves water through a hydronic heating loop, while a condensate pump removes water that collects from cooling or high-efficiency furnace operation.

What are signs of a failing circulator pump?

Signs may include uneven heat throughout a hydronic system, unusual noise, leaking at the pump body, or the pump failing to run at all.

Can I rebuild a pump instead of replacing the whole unit?

In some cases, yes. Seals, impellers, and other wear components may be available separately for rebuilding rather than replacing the entire pump.

How do I know what GPM rating I need?

Check the original pump's nameplate or the system design specifications. Matching GPM and head pressure ensures the replacement pump performs correctly in your system.
