HVACQuick.com Metlund S-50 Series Hot Water Recirculation Pumps S-50T-PF

Metlund S-50 Series DMAND System Kit. Controller and PDV (Check Valve). Two 1/2 inch compression T's with a 3/4 inch male outlet, two stainless steel flex-lines, one hard-wired button. The S-50 models are smaller pump systems designed for smaller homes. The patented PDV (Check Valve) is built into the pump housing, reducing the number of external devices. The S-50 models are adequate for runs of under 50 feet. The S-50 models carry a three year warranty. NOT FOR USE WITH TANKLESS WATER HEATERS. At the push of a button, the S-Series pumps cold water sitting in the hot water line into the cold water line and back to the water heater. The "off sensor" automatically shuts off the pump and closes the zone valve when hot water arrives at the system.
