Armstrong 182212-656 E28.2B Bronze Circulating Pump

Move high-flow potable water with Armstrong 182212-656 E28.2B, a 120 V single-phase bronze circulator for commercial hot-water loops. Its supplied 115 GPM maximum flow, 22 feet maximum head, 2-inch flanged connection, and NSF-372 and AB1953 compliance suit larger open-loop systems where material selection matters. Manufacturer reference data lists a similar E28.2B configuration with a lower published performance range, so confirm the current curve before purchase.

The dry-rotor PSC motor drives the pump through a silicon carbide mechanical seal inside the lead-free bronze body. The supplied specifications do not state amp draw, exact dimensions, unit weight, port reach, or self-priming capability. Verify the required flow and head at the operating point, then confirm flange spacing, water temperature, and service access before installation.
