Bell & Gossett B602S Series 60 Centrifugal Pump 1/3HP

B&G 172705LF Series 60 Model B602S 1/3 HP Pump

The Bell & Gossett 172705LF (Series 60, Model B602S) is a high-output All-Bronze (B), Lead-Free booster pump designed to facilitate increased fluid distribution in demanding potable water architectures. Its non-ferrous bronze construction is engineered to neutralize the hydraulic degradation common in oxygenated domestic water, while the 1/3 HP motor provides the torque necessary for larger building loops. By prioritizing an all-bronze internal and external architecture, this unit facilitates rapid thermal exchange and maintains structural stability, ensuring that hot water recirculation networks receive reliable volume without the risk of corrosion.

Driven by a powerful 1/3 HP Single Phase (S) high-torque motor, the 172705LF executes superior rotational control via the signature B&G three-piece drive assembly. The independent bearing frame is oil-lubricated to stabilize rotational frequency and neutralize mechanical noise, while a high-performance mechanical seal protects the drive assembly. By leveraging a high-strength shaft and precision-aligned components, this configuration minimizes mechanical stress and ensures maximum longevity for continuous-duty commercial potable water service.
