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

Restore closed-loop heating with Taco 1635E3E1 1/2 HP single-phase in-line centrifugal pump for commercial hydronic systems. Its 115/230-volt motor draws 7.4A or 3.7A and provides up to 115 GPM with 28 feet of head. The 30-foot shut-off head is a zero-flow reference, while the cast-iron body suits closed-loop service. Confirm the system curve before installation.

The 1635E3E1 uses a cast-iron casing with a trimmed cast-bronze impeller in a 1600 Series in-line arrangement. Its single-phase motor operates at 1,725 RPM and the supplied application identifies closed-loop hydronic heating. The 2-inch connection size, dry weight, seal, pressure, and temperature are not stated in the supplied data, so verify those details against the manufacturer’s submittal.
