HVAC Circulating Pumps

HVAC Circulating Pumps

Move liquid, air, or gas through your closed loop heating or cooling system at a consistent rate with these centrifugal-style pumps. Commonly used in light commercial and residential applications for air conditioning, refrigeration, or hydronic underfloor heating, these pumps are compact and install in-line on piping systems.

General Purpose

Use these pumps in your light duty residential or commercial installations for general purpose recirculation of liquid, air, or gas.

Continuous Duty — Closed Loop

Quiet Operation

These light duty circulating pumps have self-lubricating bearings and nonmetallic propellers to reduce motor noise, and are often used in residential heating and cooling applications.

Low Maintenance with Wet Rotor

Reduce maintenance with wet rotor pumps that are designed to self-lubricate and self-cool with the pumped water, eliminating the need for oil. They are sealless, reducing the possibility of leaks and eliminating the need for mechanical seal changes, and they don't have a fan, resulting in little to no noise during operation.

Energy Efficient with Self-Lubricating Bearings

Keep hot water quickly accessible in faucets that are farthest from the water heater with these pumps that help quickly move any cold water in the line back through the heater. These pumps are compact and designed with an ECM (electronically communicated motor) that requires less energy to run than standard motors and are more efficient. They have bearings that are self-lubricating and cooled by the fluid in the system, helping to reduce maintenance.

Compact High Performance

Recirculate water in larger residential and commercial facilities for applications such as hydronic heating, boilers, and snow melt systems. These compact pumps have higher capacity circulators than standard pumps with a smaller footprint, and feature self-lubricating bearings and nonmetallic propellers to reduce motor noise.
