Technical Specifications and Properties

The PSS Shaft Seal is a mechanical face seal, engineered to create a tight and efficient seal between the rotating stainless steel rotor and the stationary carbon flange. The carbon flange is securely attached to the vessel's stern tube with hose clamps, while the stainless steel rotor is mounted on the shaft in front of the carbon flange. This design allows for compression of the bellows, which is then secured to the shaft with set-screws, maintaining contact between the faces. The carbon flange is bored larger than the shaft diameter, enabling it to compensate for misalignment and vibration issues.

Technical Details:

• Shaft Size: 28mm
• Stern Tube Diameter: 1.750"-1.875"
• Material: Stainless Steel, Carbon
• Sealing Mechanism: Mechanical Face Seal
