Bell & Gossett 168022 Series 1535 – 351T – 1/3HP Pump

B&G 168022 Series 1535-351T 1/3 HP Pump

The Bell & Gossett 168022 (Series 1535, Model 351T) is a high-performance 3-Phase centrifugal circulator engineered to facilitate superior fluid distribution in commercial infrastructures requiring balanced electrical loads. Its robust close-coupled volute is designed to stabilize internal velocity while neutralizing the hydraulic stress common in 3-phase systems. By prioritizing a compact and efficient hydraulic architecture, this unit facilitates consistent thermal exchange and maintains structural stability, ensuring that light commercial distribution networks receive steady volume delivery during peak operational cycles.

Utilizing a 1/3 HP Three-Phase (T) high-efficiency motor, the 168022 executes superior torque delivery and electrical stability compared to single-phase equivalents. The direct-drive assembly is engineered to sustain vacuum-tight integrity, utilizing industrial-grade motor bearings to minimize mechanical friction. By leveraging a precision-aligned shaft and specialized internal seals, this configuration stabilizes rotational frequency and protects the motor core, providing long-term reliability for mission-critical commercial heating and cooling service.
