PRO shaft seal for 3" shaft and 4-1/2" tube

The PSS PRO shaft seal is a mechanical seal using our components proven seals in stainless steel and carbon. , but adds a reinforced silicone boot, we include external rings standard on +2-1/4" sizes and optional on all smaller sizes, secondary shaft retention collar, steel hose clamps 316 stainless steel (rolled, non-perforated edges) 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 environments. otherwise demanding. The PSS PRO shaft seal is a specialized mechanical seal that is suitable for a variety of applications, with unrivaled performance.

Like PSS Type A and B seals, the D seal The PRO shaft is an easy jointal mechanics. The sealing surface is created between the flat surfaces of the rotating stainless steel rotor. and the carbon stationary bridle.The carbon stationary 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, which allows it to "float" around the shaft and thus compensate for most misalignments and vibrations in the transmission. The rotor hasStainless steel 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, 3" Shaft and 4-1/2" Tube Product Description

PRO Shaft Seal, 3" Shaft and 4-1/2" Tube

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 sizes + 2-1/4" and optional on all smaller sizes, a secondary shaft retention collar, 316 stainless steel hose clamps (rolled, non-drilled edges) and 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 conditions. The PSS PRO shaft seal is a specialized mechanical seal suitable for a variety of applications. applications, with unrivaled performance.

Like PSS shaft sealsType A and B, the PRO shaft seal is a mechanical face seal. The sealing surface is created between the flanges.t 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.
