Taco 1616E 1600 Series Cast Iron Centrifugal Pump 1HP 1PH

Taco 1616E 1600 Series Cast Iron 1HP 1PH

The Taco 1616E 1HP 1PH is a high-performance in-line centrifugal pump designed for closed-loop hydronic heating and cooling systems. Mechanically, it features a rugged cast iron volute with 2-inch flanged connections, providing the structural integrity needed for high-pressure commercial HVAC applications. The close-coupled design ensures perfect concentric alignment between the 1HP motor and the impeller, reducing radial loads on the mechanical seal. The back pull-out architecture allows for internal maintenance without disturbing the main piping, ensuring efficient serviceability in busy mechanical rooms.

Powered by a 1HP single-phase motor, this pump is optimized for 115V or 230V building power. The motor features high starting torque to handle the inertia of large fluid volumes and includes internal thermal protection. Consistent electrical synchronization minimizes shaft vibration, which preserves the life of the carbon-ceramic seal faces and ensures a quiet, vibration-free operation throughout the building’s infrastructure, even during continuous-duty cycles.
