What It Is
A Proven Mechanical Face Seal for Marine Shafting
PSS Shaft Seal products are designed as mechanical face seals for marine shaft sealing applications, offering an alternative to more traditional packing arrangements and supporting cleaner, more dependable shaft sealing performance.
How It Works
Built Around a Mechanical Face Seal Design
The PSS Shaft Seal uses a rotating stainless steel rotor and a stationary carbon sealing element to create a mechanical face seal around the shaft, helping support a watertight sealing system and a cleaner bilge environment.
Why It Matters
