Bell & Gossett Series 80 Pump 4 x 4 x 9-1/2 With 5 HP 1750 RPM Motor

Description

Primary HVAC systems use Bell & Gossett Series 80 Model 4 x 4 x 9-1/2 for industrial circulation and building hydronic loops. This 5 HP in-line pump operates at 1750 RPM through a four-pole motor, while the 4-inch suction and discharge connections support large commercial piping. Its significantly trimmed 9.5-inch impeller is selected for the 5 HP curve, so confirm system duty before startup.

The Series 80 uses an in-line mounted configuration with a 4 x 4 connection arrangement and nominal 9.5-inch impeller. Precision trimming adapts the hydraulic assembly to the specified 5 HP operating curve, but verified data does not include voltage, phase, amp draw, GPM, maximum head, seal type, operating temperature, dimensions, weight, thermal protection, or self-priming capability. Support the piping independently, purge trapped air, and verify pump rotation before commissioning.
