The Taco 0011-ZF4-1IFC is a cartridge style, maintenance free, circulator pump with an Integral Flow Check (IFC). It is designed to reduce installation costs when zoning with "00" circulators on large residential or light commercial high head/medium flow applications. The reduced pressure drop of the IFC increases the 0011 flow performance over in-line check valves. The IFC and cartridge are easily accessed for service instead of replacing the entire unit.

This model features the Priority Zoning circulator with built-in transformer, relay, and priority switch to make it an ideal choice when zoning with circulators. Each zoning circulator has low and high voltage terminal strips for ease of electrical hookup, as well as a built-in priority switch. The priority switch allows the installer to choose the zone that requires the most attention and, when activated, run only that circulator. The priority zoning circulator can be used in conjunction with other circulators or zone valves. It is ideal for indirect hot water heaters, adding another zone, zoning with circulators, and for prioritizing under-sized zones.

The High Velocity series Taco 0011 Cartridge circulator pump is designed for high head/medium flow applications in residential or light commercial hydronic heating, radiant heating, and chilled water cooling systems. The unique ACB anti-condensate baffle with ambient air flow prevents the build up of condensate on the motor windings when pumping chilled water. Its unique field-serviceable cartridge contains all moving parts. Replacing the cartridge rebuilds the circulator.
