AB 110V 130W 13 GPM Hot Water Recirculating Pump – 3-Speed, 1'' FNPT Flanges

Overview

AB’s 110V 130W hot water recirculating pump accelerates warm water delivery and maintains steady circulation throughout your home’s heating and domestic water system. With a capable 13 GPM output at up to 24 ft of head and a maximum operating temperature of 230°F, this pump fits boiler loops, radiant floors, and solar-warmed setups.

The unit offers three switchable speeds, enabling you to tailor performance to your exact installation. A self-lubricating wet rotor delivers quiet, maintenance-free operation, while the included gaskets, flanges, and bolts simplify mounting and connection to your existing piping.
