Taco 120-13 Series 100 Cast Iron Pump 1/6 HP

Taco 120-13 Series 100 Cast Iron 1/6 HP

The Taco 120-13 is a mid-range three-piece circulator designed for larger residential or small commercial hydronic heating systems. Mechanically, it bridges the gap between the standard 1/12 HP units and heavy-duty 1/3 HP pumps, utilizing a 1/6 HP motor to drive a high-efficiency impeller within a cast iron casing. The modular mechanical assembly facilitates a high-volume laminar flow path, making it suitable for zoned systems where a higher USGPM is required to maintain the design temperature drop across the boiler loop.

Equipped with a 1/6 HP motor, the 120-13 provides a robust electrical drive for continuous-duty heating. The motor is coupled to the pump via the classic Taco spring coupling, ensuring that electrical pulses are not transmitted as mechanical noise into the building. This stable electrical configuration manages the load of multi-story piping runs effectively, protecting the motor windings and the mechanical seal from premature wear caused by hydraulic back-pressure.
