Armstrong 182212-675 E33.2 – 3″ Cast Iron Circulating Pump

High-flow commercial hydronics use Armstrong 182212-675 E33.2 for high-head heating loops and large building circulation. Its 120 V single-phase dry-rotor PSC motor moves up to 110 GPM against 43 feet of head through a 3-inch flanged cast iron body. Confirm the silicon carbide seal, bearing condition, flange alignment, and system curve before startup.

The Armstrong E33.2 uses a cast iron body, dry-rotor PSC motor, silicon carbide mechanical seal, and maintenance-free ball bearings. Its 3-inch flanged connection supports larger commercial headers, while the 120 V motor suits compatible single-phase circuits. Verified data does not include amp draw, RPM, impeller material, operating temperature, dimensions, weight, thermal protection, pressure-switch settings, or self-priming capability, so verify the project requirements before installation.
