The Aladdin PSR-201 Pump Shaft Seal is a professional-grade replacement designed for high-performance pool and spa pumps. Engineered for a 3/4" shaft, this critical component creates a watertight barrier between the pump housing and the motor. It effectively prevents moisture from reaching internal motor bearings, stopping premature failure and costly electrical damage. As the industry-standard "drop-in" for elite models from Pentair, Hayward, and Sta-Rite, the PSR-201 ensures a reliable, leak-free repair for your pump’s impeller assembly.
Key Features
- Precision 3/4" Fit: Specifically designed for large-shaft pumps like the Pentair WhisperFlo and Hayward Super II.
- Polished Mating Faces: High-density carbon ring and ceramic seat provide a frictionless, airtight seal.
- Stainless Steel Spring: Heavy-duty spring maintains constant tension to prevent leaks during high-pressure cycles.
- Direct OEM Replacement: Seamlessly replaces Pentair 354545S, Hayward SPX1600Z2, and Sta-Rite U109-35SS.
- Buna-N Elastomers: Durable rubber components withstand standard pool chemicals and temperature fluctuations.

?? Critical Safety & Installation Warnings
- Proper Lube: Use a water-based lubricant ONLY on the rubber jacket of the seat to slide it into the plate. Never use petroleum-based grease (like Vaseline), as it causes rubber to swell and fail.
- Alignment: Ensure the polished faces are perfectly clean and debris-free before pressing the pump halves back together.
- Impeller Check: Inspect the impeller threads and the seal plate for cracks or heat damage while the pump is disassembled.
