Armstrong 182202-648 E9.2B 240v ARMflo Bronze Circulating Pump

High-head hydronic systems can evaluate the Armstrong 182202-648 E9.2B with 240 V single-phase power, lead-free bronze construction, internal thermal overload protection, stainless steel ball bearings, and a standard two-bolt flange. Its listed maximum head is approximately 30 feet, supporting preliminary commercial HVAC and potable-water replacement screening.

The high-efficiency dry-rotor designation identifies the motor configuration, but it does not establish a specific energy-use percentage. Installation planning should verify 240 V availability, flange fitment, operating temperature, fluid compatibility, and the actual flow-head duty before approving this circulator for a project.

Key Features

- 240 V single-phase operation identifies the high-voltage electrical configuration for compatible commercial installations.
- Lead-free bronze construction provides the documented body material for potable-water application review.
- Internal thermal overload protection supports motor protection without requiring the supplied record to establish external protection.
- Stainless steel ball bearings identify the rotating support components for service-part planning.
- Approximately 30 feet of maximum head provides a preliminary hydraulic reference for system comparison.
- The standard two-bolt flange requires compatible piping and companion-flange dimensions during replacement review.
- Commercial HVAC and 240 V potable-water service define the listed application context.

Hydraulic Performance and Application

The listed maximum head is approximately 30 feet, and no exact flow curve or NPSH value is supplied. The high-efficiency dry-rotor designation describes the motor arrangement rather than guaranteed savings. Documented applications include potable-water systems requiring 240 V power and commercial HVAC circulation.

Installation Requirements

Confirm 240 V single-phase power, two-bolt flange compatibility, flow direction, rotation, internal overload protection, fluid temperature, and available service clearance before commissioning. The approximate head rating should be compared with actual system resistance, because maximum head does not define the required operating point.

Warranty and Maintenance

Armstrong provides a 30-Month Limited Warranty from date of manufacture for circulators, covering material and workmanship defects under normal use and service. Improper installation, maintenance, misuse, alteration, negligence, abnormal additives, and normal wear are excluded. Ball-bearing condition and thermal-protection operation remain relevant service checks. Mulmotor provides product-information support before purchase.
