Taco 120-13 Series 100 Cast Iron Pump 1/6 HP

Description

Residential hydronic heating uses Taco 120-13 for closed-loop circulation through boilers, radiant systems, and small heating zones. Its 1/6 HP motor operates at 1725 RPM, delivers up to 55 GPM against 14 feet of head, and connects through a 2-bolt universal flange. Fill the system, purge trapped air, and verify automatic overload operation before startup.

The Taco Series 120 120-13 uses 115 V single-phase power, a 2.10 amp full-load rating, and direct drive with spring coupling. Its ASTM A48 Class 30 cast iron casing, non-metallic polymer impeller, hardened alloy steel shaft, and carbon-ceramic seal support closed-loop hydronic operation. The pump is rated for 125 PSI, 40°F to 240°F fluid, and uses an 8-1/2-inch flange-to-flange length with a 21-pound dry weight.
