ITT Marlow Variable Speed Pump Retrofit Kit

Revitalize your spa experience with the ITT Marlow Variable Speed Pump Retrofit Kit—a true no-drill upgrade designed to restore precise jet control on older hot tubs whose factory keypad may no longer be available. This complete retrofit brings modern variable-speed performance back to life, so your massage jets deliver the perfect flow at the touch of a button.

What makes this kit stand out is the seamless, deck-friendly setup. The wireless remote arrives paired out of the box, so you can control your tub without tearing into the decking. With three customizable speeds and a smart control box that synchronizes the pump with the remote, you’ll enjoy effortless, reliable performance from start to soak.

• 1 × 120V, 8.5A Variable Speed Pump — a robust replacement compatible with ITT MARLOW, Hydro Air, and GEMINI PLUS pumps, delivering smooth, adjustable flow.
• 1 × 120V Control Box (VSPC) — the central brain that powers and coordinates the pump with the remote and push button.
• 1 × Wireless Waterproof Floating Remote — operate High/Medium/Low speeds and On/Off, with a built‑in 30‑minute timer for convenient session control.
• 1 × White Push Air Button — used to configure the system or to control the pump directly if needed, while the remote handles most functions without deck alterations.
