Taco 1614E 1600 Series Centrifugal Pump 3/4HP 1PH

Move high-flow hydronic water with Taco 1614E, a 3/4 HP close-coupled in-line centrifugal pump for residential and commercial heating systems. Its 115/230 V single-phase motor, 1-1/2-inch two-bolt flange, and 110 GPM maximum flow provide useful replacement references for larger hydronic circuits. The 50 feet maximum head also gives contractors a clear starting point for system-curve comparison.

The 1725 RPM NEMA 56 ODP motor uses a one-piece cast-bronze impeller, alloy-steel shaft with cupro-nickel sleeve, and ceramic face with EPT elastomer seal. The pump is rated for 175 psi and fluid temperatures from 40°F to 250°F. Verify the 10.6 or 5.3 amp full-load current, 12-inch flange-to-flange length, 58-pound dry weight, and required operating point before installation.
