Bell & Gossett 1.5AD Series e-1531 Pump 7.5HP Motor

Description

Using a 7.5 HP motor, Bell & Gossett e-1531 1.5AD delivers high-head commercial HVAC circulation through a close-coupled vertical in-line design. The stainless steel impeller, NEMA JM frame, and space-saving footless configuration suit chilled-water loops, pressure-boosting systems, and commercial hydronic installations where floor space and piping access require careful planning. Prime the system, verify the motor connection, and support adjacent piping before startup.

The Bell & Gossett Series e-1531 uses a 1.5 AD pump size with a stainless steel impeller and an EPR, carbon, and silicon carbide seal arrangement. Its close-coupled vertical in-line design removes the need for a separate base-mounted frame, while the NEMA JM high-efficiency motor frame supports the 7.5 HP drive. Verified data does not include voltage, phase, RPM, GPM, maximum head, connection size, operating temperature, dimensions, weight, or self-priming capability, so final selection must follow the commercial HVAC pump curve.

Key Features of Bell & Gossett e-1531 1.5AD

• 7.5 HP commercial HVAC pump for pressure boosting and chilled-water circulation.
• 1.5 AD pump size suits compatible vertical in-line piping systems.
• Close-coupled design connects the motor and pump without a separate base frame.
• Stainless steel impeller supports corrosion-conscious hydronic circulation.
• EPR, carbon, and silicon carbide seal materials support the mechanical seal assembly.
• NEMA JM frame accommodates the specified high-efficiency motor design.
• Footless construction supports space-conscious mechanical-room installation.
• Voltage, phase, RPM, GPM, maximum head, connection size, dimensions, weight, thermal protection, and warranty terms were not provided.

Why the Bell & Gossett e-1531 1.5AD Stands Out

This Bell & Gossett vertical in-line pump combines a stainless steel impeller with close-coupled construction for high-head commercial HVAC circulation.

• Build: The stainless steel impeller, multi-material mechanical seal, and NEMA JM motor frame support fixed chilled-water and hydronic installations.
• Value: Footless close-coupled construction can reduce support hardware and simplify equipment-room planning when the piping and motor loads are correctly supported.
• Audience: Commercial HVAC contractors, chilled-water installers, pressure-boosting system designers, facility engineers, and mechanical-room service teams can specify this model when the pump curve matches.

Applications & Use Cases

Use the Bell & Gossett e-1531 1.5AD for commercial chilled-water loops, high-head HVAC circulation, hydronic pressure boosting, and vertical in-line mechanical-room installations. Physical dimensions, unit weight, and suction or discharge port reach were not supplied, so verify vertical clearance, flange spacing, valve access, 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 purchase.
• Inspect the stainless steel impeller, mechanical seal, motor alignment, system fill, and piping support during commissioning.

Purge air from the loop, check the seal area for leakage, clean strainers, and verify the operating point against the system curve during service.
