Hydronic Circulating Pumps

32 products
Hydronic circulating pumps move water through a closed system of pipes in heating applications or water recirculation systems. The pump is mounted in-line near the boiler and recirculates the water through a closed-loop piping system where water does not exit the pipes. In systems that do not deliver drinkable water, the pipes and pump are constructed of cast iron. These pumps are painted red or green to help identify them as hydronic pumps and are primarily used for radiant heating in residential, commercial, and industrial buildings.

3-Piece Hydronic Circulating Pumps

3-Piece Hydronic Circulating Pumps
3-piece hydronic circulating pumps have a detachable pump, motor, and bearing assembly to aid maintenance and replacement needs. They are capable of handling higher head and flow rates than standard pumps. These pumps are mounted to the pipe in-line near the water heater or boiler and, in most cases, can be left in place while serviced which reduces system downtime.

Multi-Speed Hydronic Circulating Pumps

Multi-Speed Hydronic Circulating Pumps
Multi-speed hydronic circulating pumps have three speeds that can be manually adjusted to meet different performance levels. Pump performance needs can change based on the configuration of a plumbing system or to meet periods of low and high demand. With multiple speeds, they work well as a replacement pump because they can match the performance of most standard circulating pumps. The maximum flow at feet of head is listed at the pump's maximum speed setting. These pumps are mounted to the pipe in-line near the water heater or boiler.

    Energy Efficient Hydronic Circulating Pumps

    Energy Efficient Hydronic Circulating Pumps
    Energy efficient hydronic circulating pumps use less energy than other circulating pumps. They have an electronically commutated motor (ECM) that automatically adjusts the flow rate through variable speed control to meet hot water demand. The maximum flow at feet of head is listed at the pump's maximum speed setting. These pumps are mounted to the pipe in-line near the water heater or boiler.
