Taco 1634D Stainless In-Line Pump 1HP 1PH 2″ Flange

Taco 1634D Stainless Steel 1HP 1PH 2″ Flange

The Taco 1634D 1HP 1PH is a high-power in-line centrifugal pump featuring a 2-inch flange and a stainless steel mechanical housing. Specifically designed for large-scale open-loop and potable water systems, it provides maximum corrosion resistance and ensures water purity. The powerful 1HP motor drives a wide-vane impeller optimized for high-volume recirculation, making it ideal for the most demanding commercial plumbing networks. The stainless steel volute prevents the internal scaling and oxidation typical of oxygenated water, ensuring a long, maintenance-free service life in high-velocity applications.

Powered by a 1HP single-phase motor, the 1634D offers robust electrical performance for standard 115V or 230V circuits. The motor is thermally protected and designed for continuous duty in high-ambient temperature environments like central boiler rooms. Consistent electrical torque management minimizes shaft run-out, preserving the integrity of the carbon-ceramic seal faces and ensuring silent, vibration-free operation throughout the building’s infrastructure, even during peak demand periods.
