Armstrong 182202-664 ARMflo E11.2B 240v Cast Iron Pump

For 240 V heating loops, Armstrong 182202-664 delivers up to 33 GPM against a maximum head of 31 feet. This ARMflo E11.2 uses a cast iron body, dry-rot high-efficiency motor, stainless steel ball bearings, and inherent thermal overload protection for closed-loop heating and commercial radiant-heating systems. Confirm the 240 V supply, purge the hydronic loop, and prevent dry running before commissioning.

The Armstrong E11.2 operates on 240 V single-phase power and carries a 150 PSI maximum pressure rating. Dry-rot motor construction separates the rotor from the circulating fluid, while stainless steel ball bearings support the rotating assembly. Verified data does not include amp draw, RPM, impeller material, seal type, connection size, operating temperature, dimensions, weight, pressure-switch settings, or self-priming capability, so verify the system curve and electrical nameplate before installation.

Key Features of Armstrong 182202-664 E11.2

- 31-foot maximum head supports compatible commercial hydronic circulation.
- 240 V single-phase motor suits high-voltage branch circuits.
- Dry-rot high-efficiency motor design separates the rotor from the fluid.
- Cast iron body provides a rigid housing for fixed heating systems.
- Inherent thermal overload protection helps guard against motor overheating.
- Stainless steel ball bearings support the rotating pump assembly.
- 150 PSI maximum pressure rating supports compatible closed-loop design.
- Amperage, RPM, seal, impeller, connections, dimensions, weight, temperature, and warranty terms require confirmation.

Why the Armstrong 182202-664 E11.2 Stands Out

This Armstrong 240 V circulator combines a defined hydraulic range with thermal overload protection and dry-rot motor construction for closed-loop heating service.

- Build: Cast iron, stainless steel ball bearings, and dry-rot technology support fixed hydronic installation when water quality and system pressure remain within approved limits.
- Value: Inherent thermal protection and high-efficiency motor design can help limit nuisance trips, overheating, and unnecessary service calls.
- Audience: Commercial radiant-heating contractors, boiler technicians, HVAC installers, facility engineers, and closed-loop hydronic service teams can use this pump for compatible systems.

Applications & Use Cases

Install the Armstrong 182202-664 E11.2 in closed-loop heating, commercial radiant-heating, boiler circulation, and compatible hydronic distribution systems. Physical dimensions, unit weight, and connection reach were not supplied, so confirm pipe spacing, valve clearance, 240 V wiring access, motor service room, and installation orientation before fitting the pump.

Warranty & Support

- Factory warranty terms were not included in the supplied product data. Confirm warranty duration, electrical requirements, registration steps, and authorized support coverage before ordering.
- Verify voltage, purge trapped air, inspect the bearing and seal area, and test thermal protection during commissioning.

Clean the system strainer, monitor operating pressure, check for seal leakage, and confirm motor current during scheduled boiler maintenance.
