The 003-IFC with an Integral Flow Check (IFC®) is designed for the circulation of hot or chilled fresh water in open or closed loop applications. The IFC feature simplifies piping, eliminates separate in-line flow check, reduces installation costs and improves system performance. With its patented location at the impeller inlet, the IFC is easy to service without removing the entire unit from system piping. The unique, replaceable cartridge contains all moving parts and allows for easy service instead of replacing the entire circulator.
