The PSS PYI Type A Shaft Seal is a robust mechanical seal designed for effective protection and performance in shaft systems. It features a stainless-steel rotor that compresses a bellow against a stationary carbon flange, compensating for propeller thrust and movement. The design allows for adjustment to misalignment and vibration, with durable components and minimal wear. It operates within a temperature range of 5°F to 225°F, handles up to 15 PSI pressure, and supports shaft speeds of up to 10,000 RPM.

PSS 02-100-114 - Dripless Shaft Seal 1", 1 1/4" Stern Tube

The PSS PYI Type A Shaft Seal is a highly reliable mechanical face seal designed to provide long-lasting protection and performance for your vessel's shaft system. It utilizes a unique sealing mechanism between a rotating stainless-steel rotor and a stationary carbon flange, ensuring minimal wear and efficient operation.
- Sealing Mechanism: The stainless-steel rotor compresses the bellow against the carbon flange, compensating for propeller thrust and allowing for variable movement.
- Misalignment Compensation: The over-bored carbon flange floats around the shaft, addressing most alignment and vibration issues.
- Durable Components: The stainless-steel rotor is sealed to the shaft with O-rings that rotate along with the shaft, minimizing wear.
- Temperature Range: 5°F to 225°F (-15°C to 107°C)
- Pressure Limit: 15 PSI (1 BAR)
- Shaft Speed Limit: 10,000 RPM
- Carbon Graphite: Lapped to 4 HLB (0.000044" tolerance)
- 316SS / Nitronic 50: Faced to 9 Ra
- Bellow Material: Molded Nitrile-PVC
