Armstrong 182212-669 E33.2 2″ Cast Iron Circulating Pump
Pumping high-flow secondary boiler loops, the Armstrong 182212-669 uses an efficient 120V dry rotor motor to throw 110 GPM safely through standard two-inch flanged pipe connections.
- 110 GPM volume clears boiler lines
- 43 feet head overcomes system drag
- 120V input matches standard panel boards
- 2 inch flange simplifies line installation
- Permanently lubricated bearings eliminate oiling schedules
Description
High-flow secondary loops use Armstrong 182212-669 E33.2 for commercial HVAC and boiler circulation through 2-inch flanged piping. Its 120 V single-phase dry-rotor motor delivers up to 110 GPM against 43 feet of head, while the cast iron body, composite impeller, and permanently lubricated ball bearings support commercial service. Confirm the system curve, flange alignment, operating temperature, and motor wiring before startup.
The Armstrong E33.2 uses a 2-inch flanged connection, non-ferrous composite impeller, and maintenance-free ball bearings. Dry-rotor technology separates motor components from the circulating fluid, while the 120 V configuration suits compatible single-phase 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 verify the final project requirements.
