• Accurate, ready-to-install compatibility: designed to replace Gemini Plus II pumps and related ITT Marlow and Gemini Plus units, eliminating compatibility worries in Whirlpool and ITT Marlow-based systems.
• Robust performance at 120V: 8.5-amp motor delivers strong whirlpool action while maintaining reliability in demanding spa environments.
• Integrated air switch for easier wiring: built-in air switch simplifies control wiring and reduces installation steps when paired with the matching control system.
• Versatile, secure mounting: standard 1.5" threaded collars fit a wide range of spa plumbing configurations with a straightforward, secure connection.
• Compact, durable design: engineered for long life in moist, vibrating spa environments while keeping a compact footprint for tight engine bays.
• Broad compatibility with the Gemini Plus II family: replaces multiple models including HD10A-C, R100A-C, R100-C, R150A-C, R150-C, NRU3A-C, NRU4A-C, NRU3-C, NRU4-C, NR2A-C, 0014F88C, 0059F00C, 0060F00C, 0059F88C, and other 0034F00C Gemini Plus II variants.

How it works and control options

Voltage and current are rated at 120V and 8.5A, delivering powerful whirlpool action while remaining reliable in continuous use. Control options are flexible: with a compatible control system, the pump supports variable-speed operation for precise flow management; without a control system, it operates in straightforward On/Off mode for simple, immediate performance.

What’s included

• Pump
• Pump union
• Air switch tubing

Who this is for

• Spa and whirlpool owners upgrading a discontinued Gemini Plus II setup without sacrificing performance or reliability.
• DIY enthusiasts replacing an aging pump in Whirlpool or ITT Marlow systems, provided a suitable control arrangement is available for variable-speed operation.
• Service professionals seeking a dependable, drop-in replacement that minimizes downtime and compatibility concerns.

Practical tips for optimal results

Confirm your control system supports variable speed if you plan to utilize the adjustable flow feature; otherwise, you’ll experience On/Off operation. Use the included pump union and air-switch tubing to simplify installation and ensure a clean, leak-free connection. With the Gemini Plus II family’s proven performance, this replacement is designed to restore the spa’s original feel—quiet, efficient, and consistent whirlpool action.
