Bell & Gossett Series 80 Pump 5 x 5 x 7 With 3 HP 1750 RPM Motor

Description

Cooling tower basins rely on Bell & Gossett Series 80 to circulate large water volumes against ultra-low head conditions. This 3 HP vertical in-line pump operates at 1750 RPM through a four-pole motor and uses 5-inch suction and discharge connections for large commercial piping. Confirm the system curve, piping support, motor rotation, and flooded suction before startup to prevent air binding and hydraulic mismatch.

The Series 80 uses a nominal 7-inch impeller within a vertical in-line hydraulic assembly designed for high-volume, low-head circulation. Its 5-inch suction and 5-inch discharge ports support cooling-tower basin service and large water-transfer headers. Verified specifications do not include GPM, maximum head, voltage, phase, amp draw, seal type, operating temperature, dimensions, weight, thermal protection, or self-priming capability, so final selection must follow the approved pump curve.

Key Features of Bell & Gossett Series 80 Model 5 x 5 x 7

• 3 HP motor supports large-volume cooling-tower basin circulation and commercial water movement.
• 1750 RPM four-pole operation suits ultra-low-head hydraulic applications requiring steady circulation.
• 5-inch suction and discharge connections accommodate large commercial hydronic piping headers.
• Vertical in-line construction supports direct installation within compatible building circulation systems.
• Nominal 7-inch impeller supports high-volume water movement through the C-size hydraulic assembly.
• High-volume, ultra-low-head profile suits cooling towers and large circulation basins.
• Motor voltage, phase, amperage, seal, temperature, dimensions, weight, and thermal protection require verification.

Why the Bell & Gossett Series 80 Stands Out

This Bell & Gossett large-volume circulation pump combines large pipe connections with low-speed operation for cooling-tower and building-water applications.

• Build: Vertical in-line construction supports large piping, while final casing, seal, enclosure, and mounting details require project documentation.
• Value: Correct low-head selection can reduce unnecessary throttling, hydraulic restriction, motor loading, and cooling-tower service interruptions.
• Audience: Cooling-tower contractors, commercial HVAC engineers, facility maintenance teams, industrial water installers, and building operators can specify this model for compatible systems.

Applications & Use Cases

Use the Bell & Gossett Series 80 Model 5 x 5 x 7 for cooling-tower basins, large-volume circulation, commercial HVAC water loops, and bulk water movement. Physical dimensions, unit weight, and port reach were not supplied, so verify 5-inch pipe alignment, valve clearance, motor access, lifting requirements, 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.
• Confirm pump curve, motor data, suction conditions, phase rotation, piping alignment, and seal requirements during commissioning.

Prime the pump as required, remove trapped air, inspect connections for leakage, and monitor operating conditions during scheduled service.
