The High Velocity series Taco 0012 cartridge circulator is designed for high flow/medium head applications in large residential/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. With no mechanical seal, the self-lubricating, maintenance free design provides unmatched reliability. Compact and lightweight, with excellent performance characteristics, the 0012 is ideal for high efficiency jobs where space is a premium. Available in cast iron or bronze construction.
