Bell & Gossett 172668LF 609S Series 60 Pump 3/4 HP

B&G 172668LF Series 60 Model 609S 3/4 HP Pump

The Bell & Gossett 172668LF (Series 60, Model 609S) is a high-capacity, Lead-Free three-piece sirkulator designed to facilitate increased fluid distribution in demanding commercial plumbing architectures. Its robust casing is calibrated to stabilize internal pressure at high flow rates, while the 3/4 HP motor provides the torque necessary to overcome significant hydraulic resistance. By prioritizing a lead-free non-ferrous internal design, this unit facilitates rapid thermal exchange and maintains structural stability, ensuring that large building hot water loops receive consistent volume delivery without the risk of lead contamination.

Featuring a powerful 3/4 HP Single Phase (S) motor, the 172668LF executes superior rotational control via a precision-aligned drive assembly. The independent bearing frame is engineered to sustain vacuum-tight integrity, utilizing a mechanical seal to isolate the drive components from the system fluid. By leveraging industrial-grade bearings and a high-strength shaft, this configuration minimizes axial deflection and stabilizes rotational frequency, providing a rugged and silent solution for continuous-duty commercial service.
