Like seals. PSS type A and B, PRO shaft seal is a sealmechanical facial. The sealing surface is created between the flat surfaces of the rotating part. stainless steel rotor and the carbon fixed flange T. The carbon fixed flange is attached to a heavy duty silicone bellows which is secured to the vessel's stern tube (shaft log), with 316SS hose clamps. The stainless steel rotor is mounted on the shaft in front of the carbon flange and is used to compress the bellows, the rotor is then attached to the shaft with set screws and the shaft retention collar is installed. This compression (preload) maintains constant contact between the two contact faces of the stainless steel rotor and the carbon flange, allowing the PSS to compensate for the variable axial movement due to propeller thrust. The carbon flange is overbored relative to the shaft diameter, which allows it to "float" around the shaft and thus compensate for most misalignments and vibrations in the transmission. The roThe stainless steel tor is sealed to the shaft by two O-rings recessed into the rotor bore. These O-rings rotate with the stainless steel shaft and rotor and therefore do not suffer wear during operation.

PSS PRO Shaft Seal for 1-1/4" Shaft and 2-1/2" Tube Product Description

PRO Shaft Seal for 1-1/4" Shaft and 2-1/2" Tube 2-1/2"

The PSS PRO shaft seal is a mechanical seal using our proven stainless steel and carbon sealing components, but adds a reinforced silicone bellows, we include standard outer rings on +2-1/4" sizes and optional on all smaller sizes, secondary shaft retention collar, 316 stainless steel hose clamps (rolled edges and non-perforated) and an optional Nitronic 50 rotor upgrade (for highly corrosive environments). Designed specifically for applications that will require increased durability and resistance to harsh, corrosive, high pressure and otherwise demanding environments. PSS PRO shaft seal is a specialist mechanical seal that is suitable for a variety of applications, withunmatched performance.

As with Type A and B PSS seals, the PRO Shaft Seal is a mechanical seal. The sealing surface is created between the two flat surfaces of the rotating stainless steel rotor and the fixed carbon flange. The fixed carbon bridle is attached to a heavy duty silicone bellows which is secured to the vessel's stern tube (shaft log), with 316SS hose clamps. The stainless steel rotor is mounted on the shaft in front of the carbon flange and is used to compress the bellows, the rotor is then attached to the shaft with set screws and the shaft retention collar is installed. This compression (preload) maintains constant contact between the two contact faces of the stainless steel rotor and the carbon flange, allowing the PSS to compensate for the variable axial movement due to propeller thrust. The carbon flange is overbored relative to the shaft diameter, allowing it to "float" aroundthe shaft and thus compensate for most misalignments and vibrations in the transmission. The stainless steel rotor is sealed to the shaft by two O-rings recessed into the rotor bore. These O-rings rotate with the stainless steel shaft and rotor, and therefore do not suffer wear during operation.
