Armstrong 182202-650 E10.2B Bronze Circulating Pump

High-head potable and solar-thermal systems can consider the Armstrong 182202-650 E10.2B with 120 V single-phase power, lead-free bronze construction, dry-rotor technology, EPDM or silicon-carbide seals, and listed maximum performance of 44 GPM at 32 feet.

The compact configuration includes permanently lubricated stainless steel bearings and a standard two-bolt flange connection. The 32-foot head and 44 GPM figures are maximum references rather than simultaneous operating guarantees, so final selection requires actual system resistance and fluid-temperature review.

Key Features

- 120 V single-phase operation supports electrical compatibility checks for potable-water installations.
- Lead-free bronze construction provides the documented body material for open-loop applications.
- Dry-rotor technology identifies the motor arrangement for equipment comparison.
- Maximum flow is listed as 44 GPM, requiring comparison with actual circulation demand.
- Maximum head is listed as 32 feet, establishing an upper hydraulic reference.
- EPDM and silicon-carbide seals provide documented material references for fluid evaluation.
- Permanently lubricated stainless steel bearings reduce routine lubrication requirements.

Hydraulic Performance and Application

The listed maximum performance is 44 GPM at 32 feet, with applications including domestic hot water, solar thermal, and high-head potable systems. These values do not define the operating point, and no exact efficiency percentage or NPSH value is supplied for confirming final hydraulic suitability.

Installation Requirements

Confirm 120 V single-phase power, two-bolt flange fitment, flow direction, rotation, seal compatibility, fluid temperature, potable-water requirements, and service clearance before commissioning. The lead-free bronze body supports material review, while the 44 GPM and 32-foot limits must be checked against actual system resistance.

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. Permanently lubricated bearings reduce routine oiling, while seal inspection remains relevant. Mulmotor provides product-information support before purchase.
