Taco 122D Series 100 Stainless Steel Circulating Pump 1/4HP 115V

Taco 122D Series 100 Stainless Steel 1/4HP

The Taco 122D is a stainless steel, three-piece circulator designed for high-volume domestic water recirculation. Mechanically, it utilizes a 1/4 HP motor and a wide-vane impeller to move large quantities of water while resisting the corrosive effects of fresh, oxygenated water. The stainless steel construction ensures the unit does not introduce rust into the potable supply. The modular mechanical interface facilitates rapid maintenance, allowing the technician to service the bearing assembly without removing the pump casing from the system’s copper or pex manifolds.

Powered by a 1/4 HP 115V motor, the 122D delivers the high starting torque required to overcome system inertia in large residential estates or multi-unit buildings. The separate motor design allows for superior cooling compared to close-coupled pumps, protecting the copper windings from the high-ambient temperatures of steam or hot water rooms. This stable electrical configuration minimizes vibration, preserving the precision-ground shaft and the high-temperature mechanical seal faces.
