Armstrong 182212-663 E17.2 Cast Iron Circulation Pump

Medium-flow boiler loops use Armstrong 182212-663 E17.2 for commercial heating and hydronic circulation. Its 120 V single-phase dry-rot motor delivers up to 75 GPM against 22 feet of head, while the cast iron body, stainless steel shaft, silicon carbide seal, and maintenance-free ball bearings support boiler-loop service. Confirm the 2-bolt flange, system curve, and operating conditions before startup.

The Armstrong E17.2 uses dry-rot technology with a cast iron body and stainless steel shaft. Its silicon carbide mechanical seal supports fluid containment, while permanently lubricated ball bearings reduce routine maintenance. Verified data does not include amp draw, RPM, impeller material, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so verify the complete pump selection before installation.
