R100VS20-C Marlow Gemini Plus Pearl Whirpool Pump

Bring back the soothing power of your Pearl Bath with the R100VS20-C Marlow Gemini Plus Pearl Whirlpool Pump Replacement. This complete upgrade replaces the discontinued Pearl Gemini Plus original pump with a forward-looking, variable-speed system that delivers precise control, dependable operation, and a simpler install. You don’t need a full tub redesign—this kit integrates with your existing plumbing for a smoother, longer-lasting whirlpool experience.

What’s included

• 120V 8.5 amp Variable-Speed Pump that directly fits your old pump’s plumbing connections
• CG AIR SYSTEMS Control Box 115—the versatile hub for modern, variable-speed operation
• Variable-Speed Keypad in a white square-hole style (1-7/8" round opening; square cover fits a larger hole)
• Compact 2.5" square control interface that installs neatly under the tub
• Free union included for a straightforward, leak-reducing connection when needed

Why upgrade matters

If your Pearl system is failing or components have been discontinued, this kit delivers a complete, reliable replacement rather than patching together incompatible parts. The R100VS20-C pairs a robust, new pump with a modern control setup from one of North America’s top manufacturers of whirlpool controls, delivering smoother speed transitions, more consistent performance, and a longer service life.

Key benefits and capabilities

• True variable speed lets you tailor massage intensity and water flow—crank up for a vigorous hydro-massage, slow for a tranquil soak, or set a steady flow for consistent therapy.
• Direct-fit design means minimal downtime—the pump aligns with your existing plumbing connections, reducing guesswork during retrofits.
• Compact control solution—the 2.5" square interface tucks under the tub and responds quickly to the keypad for reliable operation.
• Safety-forward wiring—power the tub through a dedicated GFCI-protected circuit for added protection in wet environments.
• Leak-resistant, easy installation—the included union simplifies on-site connections and helps prevent misalignment and leaks.
• Minimal modification—most installations require little plumbing work, so you can return to full operation with predictable, repeatable performance.

How it works

Once installed, the pump’s variable-speed capability modulates water flow and hydro-massage intensity in real time. The CG AIR SYSTEMS Control Box 115 handles the control logic, delivering fast, responsive changes from the keypad. The compact control interface sits under the tub for unobtrusive access, while the dedicated circuit and GFCI protection keep operation safe in wet environments.

Installation and setup tips

• Prepare a stable base for the new pump to minimize vibrations and ensure longevity.
• Position the control box where it’s easily accessible but out of harm’s way for tub users.
• Use a dedicated GFCI-protected circuit for optimal safety and reliable operation.
• Check all connections with the included union (if required) and test the system before sealing the installation.
