Armstrong 182212-652 circulating pump

The Armstrong 182212-652 is a standard circulating pump rated at 2/5 hp for 120V AC single-phase supply. It suits hydronic heating, cooling or potable-water loops that require a flange-mounted circulator with a single-speed motor.

Flange connection with 8 1/2 in face-to-face

A 1 1/2 in flange connection and included flange hardware allow direct mounting between matching pipe flanges without unions. The 8 1/2 in face-to-face spacing determines whether the pump fits existing piping centres without rework.

Replaces circulators needing up to 36 ft head

The pump delivers 82 gpm at 1 ft, 72 gpm at 10 ft, 64 gpm at 15 ft and 54 gpm at 20 ft of head, with a 36 ft shut-off head. The jump is worth it when the system curve falls within this single-speed performance envelope and a flange-mounted, potable-rated unit is specified.

Questions about this item

What does the 120 V single-phase supply limit the pump to in practice?

It runs on standard household current at 120 V AC single phase, so no special wiring or three-phase service is needed.

What flange spacing and pipe size must the piping match for the 182212-652?

The pump has an 8 1/2 in face-to-face dimension and a compatible 1 1/2 in intake pipe size with the flange included.

How is the pump installed and what step is often missed?

Bolt the included flanges to the piping, align the 8 1/2 in face-to-face spacing, connect to 120 V single-phase power, and remember to prime the pump before starting.
