Armstrong 182212-667 E22.2 Cast Iron Circulator Pump

Improve high-resistance radiant heating with Armstrong 182212-667 E22.2, a 120 V single-phase ARMflo circulator rated for up to 60 GPM and 43 feet of head. Its cast-iron body and dry-rotor design suit commercial loops and radiant systems where a small residential circulator may not provide enough head. Confirm the design flow, head loss, connection layout, and installation orientation before connecting the pump.

The dry-rotor motor drives a high-performance composite impeller through a stainless-steel shaft, while the silicon carbide, carbon, and EPDM seal arrangement controls fluid around the shaft. The 120 V single-phase configuration fits compatible service panels. Amp draw, connection size, physical dimensions, weight, and self-priming capability were not supplied, so protect the pump from dry running and purge air before commissioning.

Key Features & Benefits

- 60 GPM Maximum Flow: Supports larger hydronic circuits and radiant systems requiring substantial circulation volume.
- 43 Feet Maximum Head: Gives installers a useful reference for higher-resistance commercial loops.
- 120 V Single-Phase: Connects to compatible US electrical service without requiring three-phase power.
- Dry-Rotor Technology: Provides the specified motor arrangement for commercial hydronic circulation.
- Composite Impeller: Supplies the listed high-performance impeller material for the rotating assembly.
- Stainless-Steel Shaft: Provides a corrosion-conscious shaft material for compatible loop service.
- Silicon Carbide/Carbon/EPDM Seal: Helps manage shaft leakage in specified heating-loop applications.

Why Choose Armstrong 182212-667 E22.2

The E22.2 combines a 120 V single-phase supply with a 60 GPM maximum flow and 43 feet of head, giving contractors practical data for higher-resistance radiant and commercial loops.

- Build: Cast iron, composite impeller, stainless-steel shaft, and silicon carbide/carbon/EPDM sealing provide defined construction details.
- Value: The listed flow and head ratings help contractors compare the pump against actual system resistance before purchase.
- Audience: A good fit for hydronic installers, radiant-heating contractors, commercial HVAC teams, and facility maintenance departments.

Applications & Use Cases

Apply Armstrong 182212-667 E22.2 to high-resistance commercial loops, radiant heating systems, boiler branches, and compatible hydronic distribution circuits. The supplied specifications do not state connection size, physical dimensions, unit weight, or port-to-port reach, so verify valve clearance, pipe support, motor access, service space, and required flow at operating head.

Warranty & Support

- Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with Armstrong or the seller.
- Confirm SKU 182212-667, E22.2 model details, electrical supply, and system-curve requirements before purchase.

Fill the pump and loop, purge trapped air, clean the inlet strainer, inspect the seal area, and confirm the 120 V supply before startup. Check actual flow and head during commissioning, then monitor vibration, temperature, and leakage under normal load.
