Armstrong E22.2B Series Bronze Circulating Pump

Armstrong E22.2B Bronze Pump

The Armstrong E22.2B is a high-capacity bronze circulating pump engineered to facilitate consistent fluid movement in oxygen-rich potable water systems. Its non-ferrous body is calibrated to stabilize laminar flow while neutralizing the oxidative effects that typically degrade standard pump casings. By integrating a precision-balanced rotor and stainless steel face plate, this unit optimizes hydraulic efficiency and maintains structural integrity, ensuring that commercial domestic water loops receive reliable pressure delivery without risk of mineral scaling or piping corrosion under sustained high-temperature cycles.

Featuring a high-torque motor architecture, the E22.2B executes precise rotational control to maintain constant flow rates regardless of system pressure fluctuations. The integrated design is engineered to sustain vacuum-tight integrity up to 230°F thermal thresholds, preventing elastomer breakdown and leakage at critical shaft junctions. By leveraging a ceramic shaft and carbon bearings lubricated by the system fluid, this configuration minimizes mechanical vibration and stabilizes rotational frequency, significantly extending the service life in non-ferrous applications.
