PSS 25mm Shaft / 1 1/4in Tub

Introducing the PYI - PSS Shaft Seal #02-25M-114, the premier choice for marine mechanical seals worldwide. This product is designed to provide exceptional performance and reliability, making it the top-selling marine mechanical seal in the market. With its precise fit for a 25mm shaft and a compatible stern tube diameter of 1.250" to 1.375", the PSS Shaft Seal is the ideal solution for a wide range of marine applications.
  • Superior Performance: The PSS Shaft Seal is recognized for its outstanding water tightness, ensuring a 25M% seal to prevent water entry into the bilge. This not only protects the vessel's interior but also extends the life of the propeller shaft.
  • Easy Retrofitting: Designed for easy installation, the PSS Shaft Seal can be retrofitted to shafts ranging from 3/4" (20mm) to 6" (150mm), making it versatile for various vessel types and sizes.

Key Features and Specifications

The PSS Shaft Seal is a mechanical face seal that stands out for its innovative design and advanced technology. It features a rotating stainless steel rotor and a stationary carbon flange, which work together to create a robust seal between the moving shaft and the stationary stern tube.
  • Carbon Flange: The carbon flange is attached to the stern tube and the bellows, allowing for easy installation and adjustment. It also compensates for misalignment and vibration issues, ensuring long-lasting performance.
  • Stainless Steel Rotor: The stainless steel rotor is designed to compress the bellows, maintaining contact between the faces and compensating for thrust from the propeller. This feature contributes to the seal's exceptional reliability and durability.
The PSS Shaft Seal is certified by Bureau Veritas, ABS, and Rina, further solidifying its reputation as a top-tier marine product. Boat builders and yards worldwide trust the PSS Seal due to its elimination of maintenance, constant adjustment, and cost associated with traditional packing type glands.

Why Choose the PSS Shaft Seal?

Choosing the PSS Shaft Seal means investing in a product that offers unmatched performance, ease of installation, and long-term cost savings. This product is not just a seal; it is a solution that enhances the overall efficiency and safety of your marine vessel.
  • Eliminates Maintenance: The PSS Shaft Seal reduces the need for frequent maintenance, saving you time and money over the vessel's lifetime.
  • Enhances Safety: By preventing water entry and wear to the propeller shaft, the PSS Shaft Seal contributes to the safety and longevity of your vessel.
With its extensive range of sizes and certifications, the PSS Shaft Seal is a reliable choice for both new installations and retrofitting projects. Trust the PSS Shaft Seal to deliver exceptional performance and peace of mind for your marine operations.
