Armstrong 182212-650 E19.2B Bronze Circulating Pump

High-head potable circulation uses Armstrong 182212-650 E19.2B for large domestic hot-water loops and compatible water systems. Its 120 V single-phase dry-rot PSC motor delivers up to 72 GPM against 43 feet of head, while the lead-free bronze body and silicon carbide seal support specified potable-water applications. Confirm NSF-372 compliance, maximum 230°F operation, system pressure, and water chemistry before startup.

The Armstrong E19.2B uses a lead-free bronze body, silicon carbide mechanical seal, and dry-rot permanent split capacitor motor. Its 43-foot head and 72 GPM flow limits guide high-head potable-water selection, while verified data does not include amp draw, RPM, connection size, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the domestic hot-water loop and verify the approved installation orientation.
