Armstrong E30.2B Series 2 Inch Bronze Circulating Pump

Description

Move high-volume potable water with Armstrong 182212-646 E30.2B, a lead-free bronze ARMflo circulator listed for 110 GPM and 32 feet of head. Its 120 V single-phase motor and 2-inch flanged configuration suit large hotel, hospital, and commercial hot-water loops. Manufacturer data for this model identifies up to 130 GPM and 22 feet of head, so use the current curve rather than the supplied listing values for final selection.

The dry-rot motor uses permanently lubricated stainless-steel bearings inside the bronze pump body. The verified E30.2B configuration is rated for 120 V service, approximately 2/3 HP nominal power, 3350 RPM, and 150 psi maximum working pressure. Confirm the actual flange arrangement, dimensions, weight, seal, and operating temperature before installation.

Key Features & Benefits

• 130 GPM Maximum Flow: Supports large commercial potable-water and domestic hot-water loops.
• 22 Feet Maximum Head: Provides the verified lower-head reference for high-volume system selection.
• 120 V Single-Phase: Fits compatible commercial service panels without requiring three-phase power.
• Lead-Free Bronze Body: Supports compatible open-loop and potable-water applications.
• 2-Inch Flanged Connection: Helps contractors confirm the correct larger-pipe arrangement.

Why Choose Armstrong 182212-646 E30.2B

The E30.2B is suited to larger open-loop systems where high flow matters more than high head. Correct curve selection is important because the supplied and verified ratings differ.

• Build: Lead-free bronze body, dry-rot motor, sealed bearings, and silicon carbide seal define the verified arrangement.
• Value: The corrected flow and head data helps prevent overestimating pump capability.
• Audience: Suited to plumbing contractors, hotel maintenance teams, hospital engineers, and commercial DHW installers.

Applications & Use Cases

Use Armstrong 182212-646 E30.2B for high-flow potable-water systems, hotel and hospital water loops, and compatible 2-inch flanged piping. Manufacturer data identifies up to 130 GPM and 22 feet of head, while exact dimensions, weight, and port reach require confirmation. Check pipe support, valve clearance, water temperature, and indoor orientation before installation.

Warranty & Support

• Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with Armstrong or the seller.
• Confirm the corrected E30.2B flow, head, motor data, voltage, flange configuration, and potable-water requirements before ordering.
