Large HVAC secondary loops can consider the Bell & Gossett 5BD Series e-1531 with a 20 HP, 1,750 RPM four-pole motor, three-phase power, and close-coupled 5BD case configuration.

The listed 6-by-5-by-11 case dimensions and trimmed impeller range provide replacement references for high-volume equipment review. The supplied application is large-scale HVAC secondary-loop service, but exact electrical voltage, flow, head, pressure, NPSH, and efficiency values remain configuration-dependent.

Construction Details of Bell & Gossett 5BD Series e-1531

- The 20 HP motor establishes the listed power class for electrical and starter coordination.
- Three-phase operation identifies the documented electrical phase for mechanical-room planning.
- Operating at 1,750 RPM, the four-pole motor sets the speed reference for curve selection.
- The 5BD case uses 6-by-5-by-11 dimensions for equipment-room and piping coordination.
- Close-coupled construction combines pump and motor within one assembly, affecting access and replacement planning.
- The trimmed impeller range requires exact curve confirmation before approving hydraulic selection.
- Large-scale HVAC secondary-loop service provides the stated application context for project screening.

Bell & Gossett 5BD Series e-1531 Performance

The documented application is large-scale HVAC secondary-loop service, but the supplied SKU record does not state exact flow, head, NPSH, pressure, curve, or efficiency values. Motor horsepower and speed identify the drive configuration only, so final selection requires the actual system duty point and impeller documentation.

Installation Requirements for Bell & Gossett 5BD Series e-1531

Confirm three-phase electrical requirements, 6-by-5-by-11 case dimensions, piping orientation, rotation, close-coupled service clearance, impeller trim, and system operating limits before installation. The listed trimmed impeller range should not replace exact curve documentation when matching this pump to a secondary-loop duty.
