Product Overview

The PYI PSS PRO Shaft Seal utilizes proven stainless steel and carbon sealing components but adds a reinforced silicone bellow, a secondary shaft retention collar, 316SS hose clamps and an optional Nitronic 50 rotor component upgrade (for use in highly corrosive environments). The result is a specialized dripless mechanical seal, suitable for a variety of applications with unmatched performance and durability. The PSS PRO Shaft Seal does not replace the PSS Type A Seal, but compliments the PSS Shaft Seal line with this commercially oriented offering.

How it works:

  • Two nitrile o-rings seal the stainless steel rotor to the shaft and will not experience wear
  • A primary set screw and a backup set screw (2 sets) are used to secure the stainless steel rotor to the shaft
  • A seal is created between the two mating faces of the carbon stator and the stainless steel rotor
  • Raw water is fed to the PSS Shaft Seal for cooling / lubricating the seal faces on high speed vessels
  • The stationary carbon stator is attached to the bellow, which is secured to the stern tube (shaft log)
  • The Shaft Retention Collar is attached to the shaft and helps retain the propeller or rudder shaft in your vessel in the event of catastrophic failure of the coupling or if the shaft comes free from the coupling
  • Stainless steel rings are fit to the bellow for increased strength, support and durability. External rings come standard on sizes 2-1/4" (60mm) to 3-3/4" (95mm) and optional for smaller sizes
  • 316SS hose clamps with rolled edges and non-perforated band
  • Hose clamp tail protection, clamp jackets
