Grundfos circulators are available in a wide range of materials and configurations to fit your application needs. They are suitable for heating, cooling and hot water recirculation in residential and commercial buildings. 

Grundfos offers a full line of maintenance-free circulators for moving hot water from the boiler to heating devices. Energy-efficient options feature a permanent magnet motor capable of saving up to 80 percent of energy consumption when compared with conventional circulators.

Available for both new home construction as well as retrofit projects, Grundfos hot water recirculation solutions eliminate the wait for hot water at showerheads and sink taps, preventing thousands of gallons of water from flowing down the drain as it warms.


​Grundfos circulators are specifically designed for heating and cooling systems. The wet rotor design ensures quiet maintenance free operation. Our 3-Speed models allow you the ability to adjust the pump speed to fit your specific application.
