Armstrong 182212-657 E29.2 Cast Iron Circulating Pump

Large hydronic heating needs Armstrong 182212-657 E29.2 for secondary boiler circulation and high-volume commercial heating. Its 120 V single-phase dry-rot motor delivers up to 95 GPM against 32 feet of head through a 2-inch flanged cast iron body. Confirm the thermal overload setting, stainless steel bearings, flange alignment, and system curve before startup.

The Armstrong E29.2 uses dry-rot technology, stainless steel ball bearings, and a cast iron body for large-scale hydronic heating. Its 2-inch flange supports commercial piping, while the 120 V single-phase configuration suits compatible electrical systems. Verified data does not include amp draw, RPM, impeller material, seal type, operating temperature, dimensions, weight, or self-priming capability, so confirm the final pump selection before installation.
