Armstrong 174035MF-143 H-41 AB Bronze Centrifugal Pump

Commercial potable-water systems use Armstrong 174035MF-143 H-41 AB for hot-water recirculation and compatible domestic-water service. Its 1/6 HP single-phase motor operates at 115 V, while the all-bronze lead-free body, stainless steel shaft, and Viton-ceramic mechanical seal support potable-water applications. Confirm the approximate 30-foot head, AB1953 certification, system curve, and water chemistry before startup.

The Armstrong Series 1050 H-41 AB uses a maintenance-free three-piece design with all-bronze construction and permanently lubricated components. Its approximate head value guides system selection, while verified data does not include GPM, amp draw, RPM, connection size, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the domestic hot-water duty point before installation.
