High-Performance PSS Shaft Seal

The PSS Shaft Seal, with its 45mm shaft size and 3 1/4in tub diameter, is the ultimate choice for marine mechanical sealing. This innovative seal is renowned worldwide for its exceptional performance and reliability, making it the number one selling marine mechanical seal. Its widespread adoption by reputable boat builders and yards is a testament to its quality and effectiveness. The PSS Shaft Seal is not only a standard equipment for new installations but also a premier retrofit solution for existing vessels.
  • Eliminates maintenance and constant adjustments associated with traditional packing glands.
  • Helps maintain a 100% watertight seal, preventing water from entering the bilge.
  • Reduces wear on the propeller shaft, extending its lifespan.

Key Features and Specifications

The PSS Shaft Seal boasts a unique mechanical face seal design, featuring a rotating stainless steel rotor and a stationary carbon flange. This design ensures optimal performance and durability. The carbon flange is attached to the vessel's stern tube with hose clamps, while the stainless steel rotor is fit on the shaft in front of the carbon flange. The seal's compression mechanism, achieved by securing the collar to the shaft with set-screws, 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 "float" around the shaft and compensate for misalignment and vibration issues.
  • Stationary carbon flange attached to the stern tube with hose clamps.
  • Stainless steel rotor fits on the shaft in front of the carbon flange.
  • Compression mechanism maintains contact between the faces and compensates for thrust.

Practical Uses and Benefits

The PSS Shaft Seal is an ideal solution for a wide range of marine applications, from small boats to large vessels. Its versatility and ease of retrofitting make it a practical choice for both new installations and existing vessels. The seal's ability to eliminate water in the bilge and reduce wear on the propeller shaft is particularly beneficial for maintaining vessel performance and safety. With certifications from Bureau Veritas, ABS, and Rina, the PSS Shaft Seal is a trusted choice for boat builders and owners alike.
  • Available for shaft sizes ranging from 3/4" (20mm) to 6" (150mm).
  • Easy retrofitting for existing vessels.
  • Certified by leading marine authorities for quality and reliability.
