03-200-312 - Pss Shaft Seal PSS PRO Shaft Seal for 2" Shaft & 3.5" Tube

PSS PRO Shaft Seal for 2" Shaft & 3.5" Tube

The PSS PRO Shaft Seal is designed for superior performance in demanding marine environments. This mechanical face seal features durable stainless steel and carbon components, reinforced silicone bellow, and essential external rings for sizes over 2-1/4". With a secondary shaft retention collar and high-quality 316 stainless steel hose clamps, it ensures reliable operation under high pressure. For increased protection, an optional Nitronic 50 rotor upgrade is available, tailored for corrosive environments.

Providing exceptional durability, the PRO Shaft Seal compensates for axial movement due to propeller thrust and enhances alignment handling with a floating carbon flange. This innovative design eliminates wear between the components during operation, making it a dependable choice for various marine applications.
