Bell & Gossett 172743LF 610T Series 60 Pump With 1/2 HP Motor

Replace a worn commercial circulator with Bell & Gossett 172743LF 610T, a 1/2 HP Series 60 pump for medium-flow three-phase HVAC and secondary hydronic heating. Its 2-inch flanged connections suit larger commercial piping, while the three-piece flex-coupled design gives service technicians a familiar arrangement to inspect during scheduled maintenance. Prime and vent the loop before energizing, then confirm the pump operates within the approved system curve.

The 208–230/460 V three-phase motor drives a 5-1/4-inch bronze impeller in the Series 60 maintenance-free platform. The listed 2 x 2 x 5-1/4 pump size provides the connection reference needed for replacement checks, but flow, head, pressure, amp draw, seal material, and self-priming capability were not provided. Verify flange alignment, phase rotation, suction conditions, and motor protection before startup.
