Taco 132 Series 100 Cast Iron Circulating Pump 1/2HP 115/230V

Move closed-loop HVAC water with Taco 132 Series 100, a 1/2 HP three-piece in-line circulator for commercial heating and large radiant systems. Its 115/230 V single-phase motor, 85 GPM maximum flow, and 35 feet maximum head suit larger hydronic circuits where both voltage and system resistance must be checked. The 8-1/2-inch flange-to-flange length also gives installers a useful replacement dimension.

The 1725 RPM ODP motor uses direct drive with a spring-coupled arrangement, Babbitt-lined sleeve bearings, and a two-piece carbon/ceramic mechanical seal. The cast-iron body and non-metallic polymer impeller suit closed-loop service. Verify the 7.2 amp draw at 115 V or 3.6 amps at 230 V, 31-pound dry weight, 125 psi pressure limit, and 240°F maximum fluid temperature before installation.
