Bell & Gossett 612S Series 60 Centrifugal Pump 3/4HP

B&G 172669LF Series 60 Model 612S 3/4 HP Pump

The Bell & Gossett 172669LF (Series 60, Model 612S) is a specialized Lead-Free centrifugal pump engineered to facilitate fluid movement in systems requiring specific head-to-flow performance at a 3/4 HP rating. Its non-ferrous internal construction is calibrated to neutralize the oxidative effects of oxygenated water, preventing the pitting and scaling common in high-temperature loops. This configuration facilitates consistent head pressure and maintains structural integrity, ensuring that commercial infrastructures receive precise pressure delivery while meeting all modern environmental safety standards.

Driven by a high-torque 3/4 HP Single Phase (S) motor, the 172669LF executes superior rotational stability via the signature B&G three-piece drive assembly. The motor is protected from system heat through an independent bearing housing that neutralizes mechanical noise and vibration. By leveraging a precision-ground shaft and a heavy-duty flexible coupling, this configuration stabilizes rotational frequency and ensures maximum uptime for mission-critical commercial heating and potable water applications.
