Armstrong 110116MF-305 H-54-3 LV Pump Less Volute

Description

High-rise mechanical rooms need Armstrong 110116MF-305 H-54-3 LV for large chilled-water systems requiring a 1.5 HP three-phase replacement assembly. This pump is supplied without the volute and includes a non-ferrous high-head impeller, heavy-duty maintenance-free SBA, and flexible compatibility with Armstrong Series 1050 and H-54 systems. Confirm the 8-bolt volute pattern, motor voltage, impeller position, and shaft alignment before startup.

The Armstrong H-54-3 LV uses a 208 to 230 or 460 V three-phase motor at 1725 RPM and is designed for an 8-bolt large-series volute. Its mechanical seal uses carbon and ceramic materials, with Viton available as an option, while the maintenance-free SBA eliminates routine bearing greasing. Verified data does not include GPM, maximum head, amp draw, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so verify the complete replacement configuration.
