About this spa pump

The Aqua-Flo FMXP2E 4 HP spa pump delivers reliable two-speed circulation for medium to large hot tubs requiring 230V power. This 56-frame motor features robust construction designed for continuous spa operation, with high and low speed settings that optimize water flow for filtration cycles and jet therapy. The FMXP2E series is engineered for direct replacement in spas originally equipped with Aqua-Flo pumps of matching specifications.

At Bubbles Supply, this genuine Aqua-Flo pump comes with our exact fit guarantee, same-day shipping on qualifying orders, and a full 1-year warranty for complete peace of mind. Our technical team verifies compatibility to ensure seamless installation and optimal performance. Before ordering, confirm your existing pump's voltage, horsepower, and frame size match these specifications, and always shut off power at the breaker before beginning any spa pump replacement work.
