What is the primary function of a PSS shaft seal in marine applications?
The primary function of a PSS shaft seal in marine applications is to provide a reliable and watertight seal around the propeller shaft, preventing water from entering the boat. The PSS shaft seal is a mechanical face seal, consisting of a stationary carbon flange and a rotating stainless-steel rotor, which is sealed to the shaft by two O-rings. This design allows the seal to compensate for misalignment and vibration, ensuring a consistent and effective seal without constant adjustment, thus reducing maintenance needs.
The carbon flange is attached to the front side of the bellows with hose clamps, and the rotor fits over the shaft and is secured with set screws, maintaining constant contact between the flat surfaces of the carbon flange and the rotor. This setup allows the PSS shaft seal to float around the shaft, providing flexibility and durability, making it a recognized and reliable choice for many of the world's most reputable boat builders and boatyards.
The PSS shaft seal features o-rings that rotate with the shaft, allowing the seal to compensate for any misalignment and ensuring that the rotor does not experience wear during operation. The diameter allows it to “float” around the prop shaft, providing a reliable seal. Manufactured by PYI Inc., the PSS shaft seal is recognized for its value in eliminating over-bored shaft diameters and reducing maintenance needs. As the number one selling marine mechanical seal worldwide, it is installed as standard equipment by many of the world's most reputable boat builders. The seal is available in various sizes, such as 95mm and 100mm, and is also recognized as the premiere retrofit solution, highlighting the advantages and value of installing PSS shaft seals in both new and existing boats.
What are the primary components included in the PSS Shaft Seal maintenance kits?
The primary components included in the PSS Shaft Seal maintenance kits are designed to ensure optimal performance and longevity of the mechanical seal. These kits typically include replacement O-rings that rotate with the shaft, a stainless steel rotor that fits on the shaft in front of the carbon flange, and a bellow that is secured to the shaft to compensate for compression, misalignment, and vibration problems. Additionally, the maintenance kits contain parts that create a watertight seal between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange, ensuring consistent pre-load and reducing wear during operation.
Around the shaft and thus compensating for various issues, the PSS Type B shaft seal features O-rings that rotate with the shaft, ensuring a tight seal. The PSS is designed to compensate for shaft diameter variations, allowing for retrofit applications. The seal is created between the flat surfaces of the rotating stainless steel rotor and the stationary carbon flange, which is attached to the shaft to thus compensate for most misalignment. The rotor is fit with a 20mm or 150mm recess, ensuring that it does not experience wear during operation. The gland and other components work together to provide a reliable and long-lasting seal.
The PSS shaft seal system utilizes O-rings that rotate with the shaft, allowing the seal to compensate for any misalignment. This design enables the rotor to maintain constant contact with the stationary carbon flange, ensuring that the rotor does not experience wear during operation.

Additionally, the PSS shaft seal is known for its ease of installation, cost-effectiveness, and reliable aftermarket support, making it a trusted choice in the marine industry.
What is the function of the hose in a PSS shaft seal system?
The function of the hose in a PSS shaft seal system is to create a watertight barrier around the shaft, thus compensating for any misalignment and allowing the shaft to "float." The hose is fit over the stern tube and secured with hose clamps, providing flexibility and eliminating the need for constant adjustment. This design ensures the stainless-steel rotor and stationary carbon flange maintain flat surfaces, allowing the o-rings to rotate with the shaft and prevent wear during operation. The PSS shaft seal is also recognized for its reliability in marine environments.
In addition, the PSS shaft seal system includes o-rings that rotate with the shaft, enhancing the seal's durability by ensuring consistent contact. The system is designed to compensate for various shaft diameters, allowing for a customizable fit. The stationary carbon flange is attached to the rotor, which does not experience wear during operation, further extending the system's lifespan. This comprehensive design ensures the PSS shaft seal maintains its integrity, providing a reliable solution for maintaining a watertight seal in challenging marine conditions.
The PSS shaft seal’s innovative design allows the o-rings to rotate with the shaft, ensuring the seal compensates for any misalignment. The rotor and stationary carbon flange do not experience wear during operation, maintaining a durable and effective seal. This ability to compensate for shaft diameter variations, combined with the reliable performance of the PSS shaft seal, highlights the value of using this system in marine applications. The PSS shaft seal is designed to provide a long-lasting, watertight solution, making it a preferred choice for many of the world's most reputable boat builders and marine professionals.
