Technical Specifications and Benefits

The PSS Shaft Seal features a mechanical face seal created between the rotating stainless steel rotor and the stationary carbon flange. This design ensures a precise fit and optimal performance. The carbon flange is attached to the vessel's stern tube with hose clamps, while the stainless steel rotor is securely fitted on the shaft. The collar is secured to the shaft with set-screws, creating a compression (pre-load) that maintains contact between the faces and compensates for thrust from the propeller. The carbon flange is bored larger than the shaft diameter, allowing it to compensate for misalignment and vibration issues. The stainless steel collar is sealed to the shaft using two o-rings that rotate with the shaft and stainless steel rotor, ensuring minimal wear during operation.

• Shaft Size: 60mm
• Stern Tube Diameter: 3.500" - 3.625"
