Bell & Gossett 105152 PD40S Series Centrifugal Pump 1-1/2HP BI

B&G 105152 PD40S BI Bronze Impeller Pump 1.5 HP

The Bell & Gossett 105152 (PD40S BI) is a specialized high-capacity sirkulator featuring a Bronze Impeller (BI) to facilitate enhanced longevity in corrosive or high-temperature commercial hydronic environments. The integration of a non-ferrous impeller into the robust 1.5 HP cast iron volute stabilizes fluid velocity and maintains laminar flow, providing superior resistance to the mineral scaling and oxidative pitting common in large building loops. This configuration facilitates consistent head pressure and maintains structural integrity, providing a rugged solution for high-volume heating and cooling applications requiring single-phase power.

Utilizing a 1-1/2 HP Single Phase high-efficiency motor, the PD40S BI executes precise torque delivery via the signature B&G three-piece drive assembly. The dedicated bearing frame is oil-lubricated to stabilize rotational frequency and neutralize mechanical noise, while the mechanical seal protects the drive assembly from fluid ingress. By leveraging a high-strength shaft and precision-balanced bronze components, this configuration minimizes axial deflection and stabilizes rotational frequency, ensuring maximum uptime in demanding continuous-duty service.
