Armstrong 182212-672 E30.2B 3″ Bronze Circulating Pump

Move high-volume potable water with Armstrong 182212-672 E30.2B, a 3-inch bronze circulating pump designed for large domestic-water booster loops and industrial potable systems. Its 120 V single-phase motor simplifies electrical connection in many facilities, while the 135 GPM maximum flow and 32 feet of maximum head give contractors clear starting points for pump selection. Confirm the actual operating point before installation because maximum ratings do not describe every duty condition.

The dry-rotor motor drives the pump through a silicon carbide and EPDM seal arrangement, while the lead-free bronze body suits the specified open-system application. The 3-inch flanged connection fits larger piping, but amp draw, exact dimensions, unit weight, and self-priming capability were not provided. Install with a flooded suction, flush debris from the piping, and protect the pump from dry running during commissioning.

Key Features & Benefits

- 💧 135 GPM Maximum Flow: Supports high-volume circulation through domestic-water and potable loops.
- 📏 32 Feet Maximum Head: Provides a clear selection reference for medium-head system resistance.
- 🔌 120 V Single-Phase: Simplifies connection to compatible US service panels for easier field installation.
- 🛡️ Lead-Free Bronze Body: Supports specified potable-water applications with material compliance in mind.
- 🔗 3-Inch Flanged Connection: Fits larger headers and helps maintain lower piping restriction across the loop.
- ⚙️ Dry-Rotor Motor: Separates the motor from the pumped fluid for dependable circulation service.

Why Choose Armstrong 182212-672 E30.2B?

The E30.2B is built around larger-pipe circulation rather than small residential branch service. Its bronze body, lead-free designation, and stated flow and head ratings make application matching especially important for potable-water installations.

- Build: Lead-free bronze construction, 3-inch flanges, and silicon carbide/EPDM sealing suit the specified open-system application; enclosure rating was not supplied.
- Value: The listed flow and head figures give contractors practical data for comparing the pump with domestic-water and industrial loop requirements.
- Audience: A suitable choice for plumbing contractors, domestic-water booster installers, facility engineers, and industrial potable-loop maintenance teams.

Applications & Use Cases

Apply Armstrong 182212-672 E30.2B to high-volume domestic-water booster loops, industrial potable-water circulation, and compatible 3-inch flanged piping. Exact physical dimensions, unit weight, and port-to-port reach were not supplied, so confirm flange spacing, valve clearance, lifting access, and indoor installation requirements before purchase.

Warranty & Support

- 1-Year Limited Warranty, subject to Armstrong’s applicable terms, installation requirements, and authorized service procedures.
- Confirm the fluid, piping material, electrical supply, and connection size before commissioning.

Flush the line before startup, clean the inlet strainer, purge trapped air, and inspect the silicon carbide/EPDM seal for leakage. Verify the 120 V supply, then check flow, head, vibration, and operating temperature against the design conditions.
