Taco 1612E 1600 Series Cast Iron Centrifugal Pump 1/2HP 1PH

Move closed-loop HVAC water with Taco 1612E, a 1/2 HP close-coupled in-line centrifugal pump rated for up to 95 GPM and 44 feet of head. Its 115/230 V single-phase motor and 1-1/2-inch two-bolt flange suit commercial boiler and chiller secondary loops where installers need a larger flow range than a small zone circulator provides. Confirm the duty point before installation.

The 1725 RPM NEMA 56 ODP motor uses maintenance-free sealed ball bearings, internal thermal overload, a one-piece cast-bronze impeller, and a ceramic face with EPT elastomer seal. The pump is rated for 175 psi, 40°F to 250°F fluid, and a 12-inch flange-to-flange length. Verify the 7.4 or 3.7 amp full-load current, 54-pound dry weight, and system curve before startup.
