Three-phase potable systems use Armstrong 110119MF-101 H-51-3 AB for hot-water recirculation and commercial domestic-water service. Its 1/4 HP motor accepts 208 to 230 or 460 V, while the lead-free bronze body, stainless steel shaft, and ceramic-seat mechanical seal support compatible water systems. Confirm the approximate 31-foot head, NSF-372 standard, flange alignment, and motor rotation before startup.

The Armstrong H-51-3 AB uses all-bronze lead-free construction with a three-phase motor and flanged connection. Its approximate head value guides system selection, while verified data does not include GPM, amp draw, RPM, impeller diameter, operating temperature beyond the listed application, dimensions, weight, thermal protection, or self-priming capability. Match the pump to the potable-water duty point before installation.
