Powerful, reliable, and purpose-built for larger spas, the Gecko Aqua-Flo FMCP is the OEM replacement pump you rely on for high-output hydrotherapy sessions. With 1.5 horsepower, a 115-volt two-speed motor, and 1-1/2" connections, this pump is designed to deliver the flow you need when multi-jetted tubs demand more activity from their plumbing.

Why this FMCP pump stands out

• High-performance impeller delivers flow that exceeds typical competition, making it ideal for expansive jets and demanding spa configurations.

• Long-life shaft seal and built-in overload protection help prevent leaks and protect the motor from stalling or overheating during heavy use.
• Reinforced engineered plastic construction combines durability with resistance to spa chemicals, while stainless steel volute fasteners add lasting reliability.
• Self-priming-friendly design adapts to hair and lint traps, supporting easier startup and consistent prime in a variety of spa configurations.
• 1-1/2" suction and discharge with MBT threads provide solid, universal plumbing compatibility for many spa models.
• California Title 20 compliant supports energy-use standards for modern spas.
