Cast Iron IFC Zone Pumps

The patented Taco Priority Zoning Circulator combines the reliability of the “00” circulator with the convenience and efficiency of a switching relay. With a built-in transformer, relay and priority switch, all the wiring is done directly to the circulator’s PC board, making it ideal for adding a zone or an indirect hot water heater. Paired with a removable Integral Flow Check (IFC®) is standard to simplify piping, prevent gravity flow/reverse flow, and improve system performance.
