Bell & Gossett 172738LF 608T Series 60 Pump With 1/2 HP Motor

Bell & Gossett 172738LF 608T supports medium-head three-phase hydronics in commercial HVAC zones and secondary heating loops. The 1/2 HP Series 60 pump uses a cast-iron bronze-fitted body and a 1-1/4-inch connection size, making it a useful replacement reference for compatible mechanical-room piping. Confirm the flange arrangement, system curve, and phase rotation before commissioning.

The 208–230/460 V three-phase motor drives a 4.94-inch bronze impeller within a maintenance-free Series 60 assembly. A carbon, ceramic, and Buna-N mechanical seal manages fluid around the shaft, while the three-piece flex-coupled layout supports the specified pump construction. The supplied data does not state flow, head, amp draw, dimensions, or weight, so verify those details against the submittal before installation.
