00R-F6-4IFC Radiant Heating Circulator Pump With IFC, Cast Iron, Rotated Flanges, 1/25 HP

The 00R-IFC Radiant Heating circulator with Integral Flow Check specifically fits the higher head and lower flow designs used in many Radiant Heating systems. The circulator's performance curve delivers flow that can be used in a wide combination of tube diameters and length of runs. The removable, spring loaded Integral Flow Check (IFC) prevents gravity flow/reverse flow. By locating the IFC inside the pump casing, a separate in-line flow check is eliminated, simplifying piping and reducing installation costs. It also makes for a modern, clean looking job when mounting the pump in vertical runs of pipe, pumping away from the boiler. Both the IFC and cartridge are easily accessed for service instead of replacing the entire unit.
