Taco 1615E3E1 1600 Series In-Line Centrifugal Pump 1/3HP 3PH

Move closed-loop HVAC water with Taco 1615E3E1 1/3 HP three-phase in-line centrifugal pump for industrial heating systems. Its motor operates at 208–230/460 volts and 1,725 RPM, delivering up to 65 GPM with 32 feet of head through a 1-1/2-inch two-bolt flange. The 46-pound dry weight affects handling. Confirm phase rotation, overload protection, and system curve before installation.

The close-coupled 1615E3E1 uses a cast-iron casing, diameter-trimmed cast-bronze impeller, alloy-steel shaft with cupro-nickel sleeve, and ceramic-face/EPT elastomer seal. Full-load current is listed as 1.4A or 0.7A, with 175 psi maximum pressure and a 40°F to 250°F fluid range. Sealed ball bearings require no routine lubrication. External overload protection is required for the three-phase motor.
