Taco 007-F5-7IFC Circulator Pump with IFC (Integral Flow Check) is designed to simplify piping, reduce installation costs and improve system performance. With an IFC (Integral Flow Check) inside the Taco 007-F5-7IFC model pump, the need for a separate in-line flow check is eliminated. This feature reduces a pressure drop and increases flow performance vs. in-line flow checks. Both the IFC and the cartridge are easily accessed for removal and service.
