Armstrong 182212-842 E12.2B Bronze Circulating Pump

Description

Potable hot-water systems use Armstrong 182212-842 E12.2B for domestic-water recirculation and commercial potable-water circulation. This 120 V single-phase bronze pump delivers up to 45 GPM against a maximum head of 31 feet, while NSF-372 and AB1953 certification support specified lead-free applications. Purge trapped air, verify flange alignment, and confirm water chemistry before startup.

The Armstrong E12.2B uses dry-rot PSC motor technology, a lead-free bronze body, and a standard two-bolt flange connection. Its permanently lubricated construction reduces routine service work, while the 120 V motor suits compatible electrical circuits. Verified data does not include amp draw, RPM, seal material, operating temperature, dimensions, weight, thermal protection, pressure-switch settings, or self-priming capability, so follow the system curve and approved potable-water requirements.
