Product Description

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

CONTAMINATION RISK: Do not touch the white ceramic or black carbon faces with bare fingers. Skin oils and acids will etch the faces, causing immediate premature failure.
DRY RUN HAZARD: Never power the pump without water in the housing. Friction heat will melt the seal faces and the internal rubber members within 30 seconds.
CHEMICAL RESTRICTION: Standard Buna-N elastomers are not designed for saltwater or high-ozone systems. For these applications, the Viton (PSR-201V) version is required.
ELECTRICAL SAFETY: Always disconnect power at the circuit breaker before servicing. A leaking seal allows water into the motor, creating a high risk of electrocution or fire.
💡 Professional Tips for Success
  • 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.
PROCEED WITH CAUTION: Servicing high-pressure pool equipment involves risk of injury. Professional installation by a licensed pool technician is highly recommended. Always verify the pump's 3/4" shaft requirement before installation.
NON-RETURNABLE: This is a high-precision service part. Retailers typically will not accept returns once the seal has been removed from the packaging, handled, or installed.
CALIFORNIA PROPOSITION 65 WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
WARRANTY & DATA: As a wearable maintenance component, this product typically carries no written manufacturer warranty. Reliability depends on installation technique. Specifications are sourced from Aladdin Equipment Co. and industry cross-reference charts.
