The Taco 007-F5 Cast Iron Pump is a compact, yet powerful circulator designed for quiet and efficient operation in hydronic heating systems, radiant heating, and domestic hot water recirculation. Unlike traditional pumps, the 007-F5 features a unique, replaceable cartridge containing all the moving parts. This allows for easy servicing without replacing the entire unit. #Taco #007-... https://www.partshnc.com/007-f5-taco-cipump125hp-3250rpm-115v
