Taco 1630E 1600 Series Cast Iron Centrifugal Pump 1/2HP 3PH

Circulate closed-loop HVAC water with Taco 1630E 1/2 HP three-phase in-line centrifugal pump for commercial hydronic systems. Its 208–230/460-volt motor draws 2.0A or 1.0A, while the 2-inch flange and cast-bronze impeller suit larger piping. Published capacity reaches 110 GPM and 32 feet of head. Confirm phase rotation, system curve, piping, and service access before installation.

The 1630E uses a cast-iron ASTM A48 Class 30 casing, one-piece cast-bronze impeller, and three-phase motor in a high-flow in-line arrangement. Its maximum operating pressure is 175 psi, shut-off head is 34 feet, and dry weight is 54 pounds. The supplied data does not state RPM, seal construction, flange-to-flange length, dimensions beyond the connection, or fluid-temperature limits.
