Taco 1635E3E1 1600 Series In-Line Centrifugal Pump 1/2HP 3PH

Taco 1635E3E3 1-1/2HP 1PH 1600 Series

The Taco 1635E3E3 1-1/2HP 1PH is a high-power in-line centrifugal pump designed for large-scale commercial hydronic systems. Mechanically, it features the heavy-duty 1600 Series cast iron volute with 2-inch flanges, built to withstand high static pressures and thermal stresses in extensive piping networks. The 1.5HP motor provides the significant mechanical thrust needed to maintain high flow rates, while the close-coupled design ensures perfect alignment between the motor and impeller. This alignment is critical for preserving the integrity of the mechanical seal under the high torque loads of a 1.5HP drive during continuous-duty cycles.

Powered by a 1-1/2HP single-phase motor, this model is designed for 230V operation to ensure stable amperage draw during peak loads. The motor features industrial-grade insulation and thermal overload protection, ensuring a long service life in high-demand environments. Consistent electrical torque delivery protects the internal rotating assembly from the vibrations associated with high-velocity water distribution, making it a reliable choice for large building central heating or cooling plants requiring maximum hydraulic performance.
