PSS Shaft Seal is the best-selling marine mechanical seal worldwide and is installed as standard equipment by many manufacturers. the most renowned boat builders/yards in the world. PSS shaft seal is also recognized as the leading retrofit (aftermarket) seal in the global market. Certified by Bureau Veritas, ABS and Rina: Boat builders/yards recognize the benefits and value of installing PSS as it eliminates the maintenance, constant adjustment and cost associated with traditional cable glands. OBesides these benefits, the PSS shaft seal helps eliminate water in the bilge (100% waterproof) and wear to the propeller shaft. The PSS shaft seal
can be easily retrofitted and is available for shafts ranging from 3/4"
(20 mm) to 6" (150 mm).
The PSSshaft seal is a mechanical seal created between the flat surfaces of the rotating stainless steel rotor and the fixed carbon flange. The carbon fixed bridle is attached to the ship's stern tube with hose clamps and the carbon bridle is attached to the front of the bellows with hose clamps. The stainless steel rotor is mounted on the shaft in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is attached to the shaft with set screws. This compression (preload) maintains contact between the faces and allows the
PSS to compensate for the thrust of the propeller. The carbon flange is reamed larger than the diametere of the shaft, which allows it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The stainless steel collar is sealed to the shaft by two O-rings which are recessed in the collar bore. These O-rings rotate with the stainless steel shaft and rotor and experience no wear during operation.
**As with any rubber hose below the waterline, the PSS bellows must be inspected on a regular basis for any signs of wear, aging or chemical deterioration.
PYI suggests, as preventative maintenance, that the PSS bellows be replaced every six years. When replacing the bellows, it is recommended to also replace the stainless steel rotor O-rings and adjustment screws. Sulfuric acid vapors will accelerate the deterioration of rubber, as will an ozonator.
Maintenance kit includes itemsnts you need to properly maintain your PSS shaft seal. Kit includes one (1) PSS. Below, two (2) O-rings, and five (5) sets of screws, four (4) new hose clamps and an allen key.
