Armstrong 182202-650 Circulating Pump

The Armstrong 182202-650 is a flange-mounted hot water circulating pump rated at 1/6 hp for 120V single-phase power. It delivers a maximum flow of 42 gpm at 1 foot of head and 32 gpm at 10 feet of head, making it suitable for residential or light commercial hydronic loops and potable water systems.

Verify Voltage Phase and Flange Spacing

Confirm your supply is 120V AC single-phase and that the piping presents an 8 1/2 inch face-to-face dimension with 1 1/2 inch flange connections. The pump operates at a fixed single speed and provides a maximum head of 28 ft, so the system curve must fall within this envelope.

Flanged Construction Simplifies Service

The integrated flange design allows the pump body to be unbolted without cutting pipe, reducing downtime during seal changes or impeller inspections. Rated for potable water use, the cast components resist corrosion in domestic hot water recirculation, while the single-speed motor eliminates switchgear complexity.
