Keep medium-head commercial hydronics moving with Bell & Gossett 172738LF 608T, a 1/2 HP Series 60 pump for three-phase HVAC zones and secondary heating loops. Its cast-iron bronze-fitted body and 1-1/2-inch connection size provide clear replacement references for compatible mechanical-room piping. The 4.94-inch bronze impeller completes the identification, but the system curve must still be checked before installation.

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