Armstrong S-35AB Series Circulation Pump 1/6HP

Armstrong S-35 AB Bronze Pump

The Armstrong S-35 AB is an Admiralty Bronze centrifugal pump specifically engineered to neutralize corrosion in oxygen-rich potable water and open-loop distribution systems. Its non-ferrous construction is calibrated to stabilize fluid velocity while minimizing mineral deposition and oxidative degradation on internal surfaces. By integrating a precision-balanced bronze impeller, this unit facilitates consistent laminar flow and maintains structural integrity, ensuring long-term hydraulic reliability in high-temperature domestic water circulation networks where ferrous metals would suffer from rapid pitting.

Featuring a high-performance 1/6HP single-phase motor, the S-35 AB executes precise torque delivery via synchronized power to mitigate electrical consumption at 1725 RPM. The integrated mechanical seal is engineered to sustain vacuum-tight integrity up to 225°F, preventing fluid loss in critical potable applications. By leveraging a corrosion-resistant alloy shaft and permanently lubricated bearings, this configuration minimizes axial deflection and stabilizes rotational frequency, significantly extending the mean time between failures in non-ferrous service.
