The U.S. Seal Mechanical Shaft Seal PS-3890 is a premium-grade replacement component built to fit a wide array of Jandy pump models, including the Stealth SHPF/SHPM, PlusHP PHPF/PHPM, FloPro FHPM, WaterFeature WFTR, WaterFall SWF, MaxHP MHPM series pumps, and Jandy ePump variable speed pumps. Combining carbon and ceramic sealing surfaces, this shaft seal delivers robust wear resistance and a dependable barrier against water leakage, keeping your pump running at peak efficiency. As a best practice, this seal should be swapped out every time you replace the impeller to guarantee continued leak-free operation and maximum pump longevity.

Key Benefits
