Description

Lower commercial HVAC head losses with Bell & Gossett 179046LF 90-35S, a 1/2 HP Series 90 in-line pump for low-head, high-flow primary loops. Its 2-inch AA flanged configuration gives contractors a clear piping reference, while the 5-1/4-inch bronze impeller suits compatible hydronic circulation. Confirm the 115 or 208–230 V supply, flange spacing, system curve, and pump orientation before replacement.

The single-phase motor operates within the supplied voltage range and drives the bronze impeller through a close-coupled, maintenance-free assembly. Flow, head, pressure, amp draw, seal material, dimensions, and weight were not provided. Verify the current Series 90 submittal, flooded suction conditions, valve access, and motor service clearance before installation.
