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

Taco 1635E3E3 1600 Series 1-1/2HP 3PH

The Taco 1635E3E3 1-1/2HP 3PH represents the industrial peak of the 1635 series, combining a high-capacity cast iron volute with a powerful three-phase drive. Mechanically, it is engineered for maximum hydraulic stability, utilizing a precision-machined impeller to deliver a smooth laminar flow eye even at peak GPM. The 2-inch flanged mechanical interface is designed for high-velocity fluid displacement, while the back pull-out architecture ensures that maintenance technicians can access the seal and impeller without disturbing the main piping, providing maximum uptime for critical building infrastructure.

Featuring a 1-1/2HP three-phase motor, this model offers the highest level of electrical efficiency and reliability for commercial grids (208-230/460V). The 3-phase configuration provides a more balanced load and constant torque, eliminating the mechanical wear associated with the start-stop cycles of single-phase motors. This stable electrical configuration minimizes harmonic noise and vibration, protecting the precision-ground shaft and high-load bearings for the longest possible service life in industrial HVAC applications.
