B&G 168313LF e3509S Series e-1535 Pump 1/2 HP

The Bell & Gossett 168313LF (Series e-1535, Model e3509S) is a specialized high-efficiency centrifugal pump engineered to facilitate fluid movement in systems requiring targeted head-to-flow ratios at 1/2 HP. Its Lead-Free construction is calibrated to neutralize the oxidative effects of oxygenated water, while the “e” series impeller geometry facilitates efficient thermal distribution. This unit is designed to provide reliable volume delivery in commercial plumbing architectures where both high-efficiency energy standards and lead-free compliance are primary design requirements.

Driven by a high-efficiency 1/2 HP Single Phase (S) motor, the 168313LF executes superior power delivery with optimized electrical draw. The motor is engineered to sustain vacuum-tight integrity and features advanced electronic protection to neutralize the risk of thermal stress during continuous operation. By leveraging a precision-ground shaft and industrial-grade bearings, this configuration minimizes mechanical vibration and stabilizes rotational frequency, providing a silent and highly reliable solution for modern, high-efficiency plumbing infrastructures.
