Marquis 1.5 HP (115V) 2-Speed 48-Frame Pump (630-6087)

The Marquis 1.5 HP is a manufacturer-identified replacement pump for a compatible Marquis Spas installation. Correct pump selection depends on more than advertised horsepower: electrical supply, motor current, speed configuration, the shape of the wet end, connection sizes, and how the pump is mounted all affect whether the assembly can be installed safely.

Purpose-Built Spa Water Movement

Spa hydrotherapy pumps move water through a closed set of suction and jet plumbing. In a compatible two-speed arrangement, a controller can request different operating modes for different spa functions. The system manufacturer determines the proper speed selection and which connected functions are supported.

A worn impeller, leaking seal, failed motor, or other pump problem may lead a spa owner to consider a complete replacement. Before replacing the assembly, identify the actual failure, examine the surrounding plumbing and electrical connections, and make sure the existing control equipment is suitable for the proposed motor.

Selecting the Correct Replacement Assembly

Marquis uses equipment-specific pump configurations, and names such as Aqua-Flo and Vico can refer to different original equipment designs. The pump may have its own manufacturer label in addition to the spa model identification. Compare both identifiers when possible. An identical voltage does not establish compatibility if speed count, amperage, connection layout, or physical footprint differs.

Installation and Service Considerations

A suitable replacement should connect without forcing rigid plumbing into alignment or placing stress on the pump housing. Check the intake and discharge layout, existing union faces and gaskets, mounting footprint, ground/bond connections, and the available clearance around the motor. Electrical and hydraulic servicing should follow the original equipment instructions.

• Manufacturer-specific replacement selection helps avoid incompatible motors that happen to share an advertised horsepower rating.
• Match the original pump label and the installed spa controller before selecting an electrical replacement.
• Check wet-end connection orientation and union alignment before disconnecting or cutting existing plumbing.
• Inspect pump housing seals and nearby plumbing for leaks during replacement planning.
• Confirm installation footprint, airflow around the motor, and proper grounding and bonding.
• Do not assume a cord, unions, or brackets are included unless expressly identified in the supplier description.

Before ordering: Match Marquis part 630-6087 to the original equipment documentation. The pump is sold as the identified assembly, not as a universal fit for every Marquis spa.
