Handle higher-resistance potable-water circulation with Armstrong 182212-668 E22.2B, a lead-free bronze ARMflo circulator for solar thermal and domestic hot-water systems. The supplied listing shows 60 GPM and 43 feet of head, while Armstrong’s current E22.2B submittal identifies approximately 88 GPM and 39.5 feet. Use the verified ratings for final pump selection.

The dry-rot, two-pole motor operates at approximately 3350 RPM on 120 V single-phase power. The pump uses permanently lubricated stainless-steel bearings and a silicon carbide seal with Viton elastomer. Verified data lists 150 psi maximum working pressure and 230°F maximum fluid temperature. Confirm amp draw, dimensions, weight, flange details, and indoor orientation before startup.
