Aladdin PSR-100 Pump Shaft Seal
The Aladdin PSR-100 is an individually boxed mechanical pump shaft seal designed for compatible pool and spa pump applications. This two-piece replacement seal helps prevent water from leaking between the pump wet end and motor shaft. It is commonly replaced during motor changes, pump rebuilds, and repairs involving water leakage near the seal plate or motor.

Important Compatibility Notes
- Confirm the pump model, seal plate configuration, and original seal part number before ordering.
- Do not select a shaft seal using the motor model alone. The correct seal is determined by the pump wet end and seal plate design.
- Some pump series were produced with different seals depending on the manufacturing year or pump configuration.
- This listing includes the pump shaft seal only. O-rings, gaskets, and other wet-end components are sold separately unless specifically stated otherwise.
Installation Notes
- Turn off electrical power and relieve system pressure before servicing the pump.
- Clean the seal plate and mating surfaces before installing the new seal.
- Avoid touching the polished ceramic and carbon seal faces with bare hands.
- Do not apply lubricant to the polished mechanical seal faces unless specifically directed by the pump manufacturer.
- After reassembly, prime the pump and inspect the seal plate and motor area for leaks.

Maintenance Tips
- Replace the shaft seal whenever the pump motor is replaced to reduce the risk of leaks and premature motor failure.
- Inspect the seal plate for cracks, corrosion, or worn sealing surfaces before installing a new seal.
- Replace flattened, brittle, or damaged O-rings while the pump is disassembled.
- Address water dripping near the motor promptly, as continued operation can damage bearings and electrical components.
- Never run the pump dry. Dry operation can overheat and damage a mechanical shaft seal.
