The High Velocity Series Taco 0013 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 wind-ings 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 Stainless Steel construction.
