Bell & Gossett Series 80 Pump 3 x 3 x 9-1/2 B With 7-1/2 HP 1750 RPM Motor

Description

Space-constrained HVAC piping suits Bell & Gossett Series 80 Model 3 x 3 x 9-1/2 B for high-flow circulation through building hydronic systems. Its 7.5 HP vertical in-line pump uses 3-inch suction and discharge connections, a 9.5-inch nominal impeller, and a 1750 RPM four-pole motor. Confirm flange alignment, vertical motor clearance, hydraulic demand, and piping support before startup.

The Series 80 uses an in-line mounted configuration with a vertical NEMA-standard motor and 9.5-inch nominal impeller. Its 3-inch suction and discharge connections support high-flow HVAC piping, while verified data does not include GPM, maximum head, voltage, phase, amp draw, seal type, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Select the pump from the approved curve and prevent air entry during commissioning.

• Audience: Commercial HVAC contractors, building engineers, boiler technicians, hydronic designers, and facility maintenance teams can specify this model.

Applications & Use Cases

Use the Bell & Gossett Series 80 Model 3 x 3 x 9-1/2 B for high-flow HVAC, building hydronics, chilled-water circulation, and space-conscious commercial piping. Physical dimensions, unit weight, and port reach were not supplied beyond the pump designation, so verify 3-inch flange spacing, motor clearance, valve access, lifting room, and structural support before installation.

Warranty & Support

• Warranty: Bell & Gossett general product terms provide one year from installation or 18 months from product date code, whichever occurs first.
• Verify phase rotation, purge trapped air, inspect flange joints, confirm vertical clearance, and check the seal area during commissioning.

Flush debris, support the connected piping, inspect for leakage, and confirm the operating point during scheduled HVAC maintenance.
