Circulating Pumps, Flanges, Unions & Controls

492 products
Circulating pumps move water through pipe systems to deliver hot water to faucets and shower heads, or to provide radiant heat to floors and radiators. They conserve water by delivering hot water faster than gravity-fed systems. Potable circulating pumps operate in an open loop system where drinkable water exits the pipes for use. Hydronic circulating pumps operate in a closed loop system where the water recirculates continuously within the pipes to deliver radiant heat. Flanges and unions are used to mount pumps inline into pipes, and controls provide adjustments to water temperature and the operating duration of the pump. Repair parts and kits match to the compatible brand, series, and manufacturer number of the pump.
