Armstrong 182212-655 E28.2 Cast Iron Circulating Pump

Description

Need 115 GPM for HVAC circulation? Armstrong 182212-655 E28.2 handles high-volume fluid movement with a cast iron body, 2-inch flanged connection, and 22-foot maximum head. This 120 V single-phase dry-rotor circulator suits heavy commercial HVAC systems where high flow, reliable flange alignment, and service access matter. Fill the loop, remove trapped air, and confirm the flange connection is not carrying unsupported pipe weight before startup.

The Armstrong E28.2 provides up to 115 GPM through a high-performance composite impeller and operates within a 150 PSI maximum pressure rating. Its dry-rotor motor separates the rotor from the fluid, while the 2-inch flanged connection supports larger commercial hydronic piping. Verified data does not include amp draw, RPM, seal type, operating temperature, dimensions, weight, thermal protection, pressure-switch settings, or self-priming capability, so confirm the system curve and motor nameplate before installation.

Key Features of Armstrong 182212-655 E28.2

• 115 GPM maximum flow for heavy commercial HVAC circulation.
• 22-foot maximum head for high-volume, lower-head hydronic systems.
• 120 V single-phase motor suits compatible commercial branch circuits.
• Dry-rotor technology separates the motor rotor from the pumped fluid.
• Cast iron body supports fixed commercial circulation installations.
• High-performance composite impeller supports high-volume water movement.
• 2-inch flanged connection suits larger hydronic pipe headers.
• 150 PSI maximum pressure rating supports compatible commercial loop design.
• Amperage, RPM, seal, temperature, dimensions, weight, thermal protection, and warranty terms require confirmation.

Why the Armstrong 182212-655 E28.2 Stands Out

This Armstrong high-volume HVAC circulator combines a 2-inch flange, composite impeller, dry-rotor motor, and published flow and head limits for commercial systems.

• Build: Cast iron construction, a high-performance composite impeller, and dry-rotor technology support high-volume commercial water circulation.
• Value: The large connection and defined hydraulic range help contractors match the pump to high-volume headers without relying on an undersized circulation path.
• Audience: Commercial HVAC installers, facility engineers, boiler-room technicians, hydronic contractors, and industrial maintenance teams can use this model for compatible high-volume loops.

Applications & Use Cases

Install the Armstrong 182212-655 E28.2 in heavy commercial HVAC systems, high-volume hydronic headers, chilled-water loops, and large building circulation circuits. Physical dimensions, unit weight, and flange reach were not supplied, so verify 2-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 duration, installation requirements, registration steps, and authorized service coverage before ordering.
• Inspect flange gaskets, purge air, clean strainers, verify flow direction, and check the mechanical seal during commissioning.

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