Bell & Gossett Series 80 Pump 4 x 4 x 7 With 1-1/2 HP 1750 RPM Motor

Description

Bell & Gossett Series 80 moves high-volume water through 4-inch suction and discharge connections in cooling-tower transfer and quiet-loop circulation applications. The 1.5 HP, 1750 RPM motor and nominal 7-inch impeller fit low-head systems where large pipe connections help reduce velocity and flow restriction. Confirm the system curve, motor electrical data, mounting arrangement, and available mechanical-room clearance before installation.

This in-line mounted centrifugal pump uses a 4-inch suction and 4-inch discharge layout with a four-pole motor operating at 1750 RPM. The supplied data identifies a nominal 7-inch impeller and very low port velocity, but it does not state GPM, head, pressure, voltage, phase, amp draw, dimensions, or weight. Verify the final pump selection against the approved operating point and piping plan.

Key Features & Benefits

• 1.5 HP Motor: Supports high-volume circulation in compatible commercial HVAC systems.
• 1750 RPM Speed: Provides a slower four-pole operating reference for quiet-loop applications.
• 4-Inch Suction: Accommodates the specified larger inlet connection for high-volume piping.
• 4-Inch Discharge: Matches the listed outlet size for compatible system layouts.
• 7-Inch Nominal Impeller: Identifies the primary rotating component for equipment comparison.
• Very Low Port Velocity: Supports large-pipe layouts where reduced fluid velocity is important.
• In-Line Mounted Design: Fits systems arranged around a direct piping run rather than a base-mounted pump.

Why Choose Bell & Gossett Series 80 4 x 4 x 7

The Series 80 configuration is intended for large-pipe circulation where low port velocity and a 1750 RPM motor are more important than compact residential installation.

• Build: In-line mounting, 4-inch connections, four-pole motor, and nominal 7-inch impeller define the pump arrangement.
• Value: Larger connections and lower port velocity can help reduce piping restriction in compatible high-volume systems.
• Audience: Designed for commercial HVAC contractors, cooling-tower technicians, facility engineers, and industrial maintenance teams.

Applications & Use Cases

Apply Bell & Gossett Series 80 4 x 4 x 7 to quiet loop circulation, cooling-tower transfer, large HVAC headers, and compatible low-head systems. The supplied information does not include overall dimensions, unit weight, flange-to-flange length, voltage, or phase, so confirm base or pipe support, lifting access, alignment, and service clearance before installation.

Warranty & Support

• Warranty Terms Require Confirmation: Verify duration, coverage, registration, exclusions, and authorized service requirements with the seller.
• Confirm the 4 x 4 x 7 configuration, 1.5 HP motor, 1750 RPM speed, and impeller size before purchase.

Inspect the suction and discharge piping, verify the motor nameplate, prime the system, and purge trapped air before startup. Check for vibration, unusual noise, seal leakage, and unstable flow during commissioning.
