Hydronic Circulating Pumps

Available1 product
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.

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.
