Taco 133 Series 100 Cast Iron Three-Piece Circulating Pump 3/4HP

Taco 133 Cast Iron Three Piece 3/4 HP

The Taco 133 is a high-performance commercial-grade circulator, representing the heavy-duty end of the three-piece inline series. Mechanically, it utilizes a powerful 3/4 HP motor to drive a high-velocity impeller through a massive cast iron volute. This configuration is engineered to handle the high head pressures and friction losses found in multi-story commercial buildings. The three-piece modular design ensures that the high torque of the drive is managed by a dedicated bearing assembly, protecting the hydraulic end from mechanical stress and ensuring a long service life.

Driven by a 3/4 HP motor, the Taco 133 provides the immense electrical power required for high-velocity water distribution. The motor is coupled to the pump via a heavy-duty spring coupling, which effectively dampens the electrical pulses and start-up torque. This stable electrical-to-mechanical interface maintains a constant 1750 RPM performance curve, preserving the life of the mechanical seal and ensuring that the pump remains a reliable heart for the building’s central heating or cooling plant.
