Bell & Gossett 168023 Series 1535 – 352S – 1/2HP Pump

B&G 168023 Series 1535-352S 1/2 HP Pump

The Bell & Gossett 168023 (Series 1535, Model 352S) is a mid-range close-coupled centrifugal pump designed to facilitate increased fluid distribution in commercial hydronic networks. Its robust cast iron casing is calibrated to stabilize internal pressure at higher flow rates, while the 1/2 HP motor provides the torque necessary to overcome moderate system resistance. By prioritizing an integrated motor-and-volute architecture, this unit facilitates rapid thermal distribution and maintains structural integrity, ensuring that commercial building loops receive consistent pressure delivery without the footprint of a base-mounted pump.

Driven by a 1/2 HP Single Phase (S) high-torque motor, the 168023 executes superior rotational control for efficient volume delivery. The motor is engineered to sustain vacuum-tight integrity under continuous-duty cycles, utilizing a precision-ground shaft to neutralize mechanical vibration. By leveraging high-quality internal seals and industrial bearings, this configuration minimizes mechanical stress and stabilizes rotational frequency, providing a reliable and silent solution for primary or secondary circulation in modern HVAC architectures.
