Bell & Gossett 105151 PD40S Series Centrifugal Pump 1-1/2HP

Description

Bell & Gossett 105151 PD-40S handles large commercial hydronic heating with a 1-1/2 HP single-phase motor and three-piece modular in-line construction. Its cast-iron body, steel or alloy impeller, and oil-lubricated sleeve bearings suit high-flow HVAC loops where planned maintenance access is available. Confirm the pump curve, voltage, connection size, and lubrication requirements before installation.

The motor accepts 115 or 208–230 V power and transfers rotation through the three-piece Series PD-40S assembly. The supplied data does not state flow, head, pressure, amp draw, RPM, dimensions, weight, seal material, or flange details. Verify the actual system duty point, pipe alignment, suction conditions, and service clearance before startup.
