This is a complete repair kit for the impeller on your Zodiac Jandy FloPro FHPM series pool or spa pump. It's for the 2-horsepower models. The kit includes the impeller itself, the screw, the screw O-ring, and the backplate O-ring – everything you need to get your water flow back to normal. If your pump is making noise, losing pressure, or just not moving water like it should, a worn impeller might be the culprit. Installation is a common maintenance task if you're handy, but make sure to follow proper procedures. A genuine Zodiac part that ensures a perfect fit and reliable performance for your pool system.
