Armstrong 182212-671 E30.2 – 3″ Cast Iron Circulating Pump

At 135 GPM, Armstrong 182212-671 E30.2 supports high-volume commercial hydronics through a 3-inch flanged cast iron pump body. Its 120 V single-phase dry-rotor motor, 32-foot maximum head, and thermal overload protection suit primary heating loops and large building circulation systems. Install the pump horizontally or vertically as permitted, purge the loop, and support the 3-inch piping independently before startup.

The Armstrong E30.2 uses a 3-inch flanged connection with a high-performance composite impeller and a cast iron body. Dry-rotor technology separates the motor rotor from the fluid, while the 120 V motor and thermal overload protection support compatible commercial heating installations. Verified data does not include amp draw, RPM, seal type, operating temperature, dimensions, weight, pressure-switch settings, or self-priming capability, so verify the system curve, flange arrangement, and electrical requirements before installation.

Key Features of Armstrong 182212-671 E30.2

- 135 GPM maximum flow for high-volume commercial hydronic circulation.
- 32-foot maximum head for primary heating-loop design.
- 120 V single-phase motor suits compatible branch circuits.
- Dry-rotor technology separates the motor rotor from the pumped fluid.
- Cast iron body supports fixed commercial heating installations.
- High-performance composite impeller supports large-volume water movement.
- 3-inch flanged connection suits larger hydronic pipe headers.
- Horizontal or vertical in-line mounting supports flexible equipment-room layouts.
- Thermal overload protection helps guard against motor overheating.

Why the Armstrong 182212-671 E30.2 Stands Out

This Armstrong high-volume hydronic pump combines a 3-inch flange, composite impeller, dry-rotor motor, and thermal protection for primary heating loops.

- Build: Cast iron, high-performance composite, and dry-rotor construction support commercial circulation when the fluid, pressure, and temperature remain within approved limits.
- Value: Large flanged connections and a defined flow range help reduce header restriction, poor circulation, and pump mismatch.
- Audience: Commercial HVAC contractors, boiler installers, facility engineers, hydronic designers, and industrial maintenance teams can specify this model for compatible high-volume loops.

Applications & Use Cases

Install the Armstrong 182212-671 E30.2 in primary heating loops, high-volume commercial hydronics, boiler headers, and large building circulation systems. Physical dimensions, unit weight, and flange reach were not supplied, so verify 3-inch pipe alignment, bolt clearance, valve spacing, motor access, wiring position, and lifting requirements before installation.

Warranty & Support

- Factory warranty terms were not included in the supplied product data. Confirm warranty coverage, electrical requirements, registration steps, and authorized service support before purchase.
- Inspect flange gaskets, purge trapped air, clean strainers, verify flow direction, and test thermal protection during commissioning.

Support connected piping, monitor the cast iron body for leakage, and confirm flow and operating pressure during scheduled HVAC maintenance.
