Move high-flow building HVAC water through a compact vertical in-line system with Bell & Gossett Series e-80 Model 3 x 3 x 9.5C. This 7.5 HP pump uses 3-inch suction and discharge connections, a 1750 RPM four-pole motor, and a 9.5-inch C-size volute for main building circulation. Confirm system fill, flange alignment, motor protection, and hydraulic requirements before startup to avoid air binding and operating-point mismatch.

The Bell & Gossett e-80 uses a vertical in-line configuration with a 3-inch suction and 3-inch discharge path. Its internal self-flushing mechanical seal supports seal-area cleanliness, while the 1750 RPM motor drives the full hydraulic assembly through the 9.5-inch nominal impeller arrangement. Verified data does not include voltage, phase, amp draw, GPM, maximum head, seal materials, operating temperature, dimensions, weight, thermal protection, or pressure-switch settings, so final selection must follow the approved pump curve.

- Voltage, phase, amp draw, GPM, maximum head, seal material, temperature, dimensions, weight, thermal protection, and warranty terms require confirmation.

Why the Bell & Gossett Series e-80 Model 3 x 3 x 9.5C Stands Out

This Bell & Gossett vertical in-line pump combines large pipe connections, a self-flushing mechanical seal, and a 7.5 HP drive for main building circulation.

- Build: The vertical in-line casing, 3-inch connections, and internal self-flushing seal support large commercial HVAC installations with suitable piping support.
- Value: In-line placement can simplify header routing, while correct curve matching helps reduce air problems, overload events, and unplanned service.
- Audience: Commercial HVAC contractors, building engineers, district-energy technicians, boiler-room teams, and facility maintenance managers can specify this pump for compatible high-flow loops.

Applications & Use Cases

Use the Bell & Gossett Series e-80 Model 3 x 3 x 9.5C for main building HVAC, chilled-water circulation, commercial heating loops, and high-flow hydronic headers. Physical dimensions, unit weight, and port reach were not supplied, so verify 3-inch pipe alignment, flange clearance, vertical lifting access, valve spacing, motor service room, and piping support before installation.

Warranty & Support

- Factory warranty terms were not included in the supplied product data. Confirm warranty coverage, motor requirements, installation conditions, and authorized service support before ordering.
- Purge air, inspect the self-flushing seal area, confirm motor rotation, and verify system flow during commissioning.

Flush debris from the loop, protect the suction path from air entry, and inspect the seal and flange joints during scheduled HVAC maintenance.
