Download Literature Watch VideoPSS Shaft Seal 03-200-234 Prop Shaft SealsSilicone Shaft Seal 2" Shaft & 2-3/4" TubeThe PSS PRO Shaft Seal is a mechanical face seal utilizing PSS's proven stainless steel and carbon sealing components, with a few additions. These additions include adding reinforced silicone bellows, 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, the PSS PRO Shaft Seal is a specialized mechanical seal that is suitable for a variety of applications and has unmatched performance.Features: 2 in. shaft diameter  2-3/4 in. to 2-7/8 in. stern tube diameter Certifications: ABS Certified RINA Certified Bureau Veritas Certified How Does it Work?Two nitrile o-rings seal the stainless steel rotor to the shaft and will not experience wear.The Shaft Retention Collar is attached to the shaft and helps retain the propeller or rudder shaft in a vessel in the event of catastrophic failure of the coupling or if the shaft comes free from the coupling.A seal is created between the two mating faces of the carbon stator and the stainless steel rotor.A seal is created between the two mating faces of the carbon stator and the stainless steel rotor.Raw water is fed to the PSS Shaft Seal for cooling / lubricating the seal faces on high speed vessels.Hose clamp tail protection, Clamp Jackets.The stationary carbon stator is attached to the bellows, which is secured to the stern tube (shaft log).316SS hose clamps with rolled edges and a non-perforated band.Shaft Retention Collar The PYI Shaft Retention Collar is designed to help retain the propeller or rudder shaft in a vessel in the event of catastrophic failure of the coupling or if the shaft comes free from the coupling. The double split design provides maximum axial holding power with the benefit of quick and efficient assembly with the shaft installed. The design fully engages the shaft without marring. Easily installed where major disassembly would otherwise be required. Greater axial holding power than set screws or one-piece clamping collars. Effective on hard and soft shafts.RotorThe PSS stainless steel rotor is slid down the shaft and secured to the shaft with set screws at 90° for maximum holding power. Precision tolerances are maintained by computer-controlled lathes. The faces have a number 9 micro finish and are perpendicular to the bore to prevent run-out as the collar rotates. The carbon graphite stator will polish the face of the rotor during the first few minutes of operation. The stainless steel rotor should not need to be replaced under normal operating conditions. The stainless steel rotor used on the PSS Type A Shaft Seal is made from 316L stainless steel.Carbon StatorThe high-density resin-impregnated carbon/graphite stator is a composite that is first mixed, molded, and then formed under pressure. The blanks are then baked, machined, and lapped. The face of our carbon is finished to a flatness of 4 helium light bands (measured .000044" of variation over the entire lapped surface). The grade of carbon used in the PSS has an operating temperature of over 500° Fahrenheit (+260° Celsius) and cannot melt if the seal runs dry, unlike a rubber lip seal or plastic face seal. The high density of the carbon greatly increases its longevity and wear resistance. Several commercial vessels have recorded over 40,000 (over 4-1/2 years of continuous operation) engine hours on the same, original components. The carbon should not need to be replaced under normal operating conditions.BellowThe PSS PRO Shaft Seal bellow provides the best combination of durability, strength, and elasticity. It's constructed of four-ply aramid or silicone with a flurosilicone outer. This flurosilicone cover creates an oil- and fuel-resistant barrier, protecting the exterior surface from the possibility of damage from a splash or spill. Both ends of the bellow are sealed. The four-ply cloth inlay provides excellent strength and resistance to abrasion. This bellow has a continuous operating temperature range of -90°F to +425°F (-70°C to +220°C).

PSS Shaft Seal PSS Shaft Seal 45mm Shaft 3-1/4" Tube #02-45M-314 $536.00 $617.32
PSS Shaft Seal 02-45M-314 Prop Shaft SealsShaft Seal 45mm Shaft & 3-1/4" TubeThis Type A PSS Shaft Seal is a mechanical face seal. The sealing surface is created between the flat surfaces of the rotating stainless-steel rotor and the stationary carbon flange. The PSS Shaft Seal is the #1 selling marine mechanical seal worldwide and is installed as standard equipment by many of the world's most reputable boat builders and boat yards. The PSS Shaft Seal is also recognized as the premiere retrofit (aftermarket) seal on the world market. Boat builders and boat yards recognize the advantages and value of installing the PSS, as it eliminates the maintenance, constant adjustment, and cost associated with traditional packing-type glands. Aside from these benefits, the PSS Shaft Seal helps to eliminate water in the bilge (100% watertight) and wear to the propeller shaft. How Does it Work? Two nitrile o-rings seal the stainless steel rotor to the shaft and will not experience wear. A primary set screw and a backup set screw (2 sets) are used to secure the stainless steel rotor to the shaft. A seal is created between the two flat surfaces of the carbon stator and the stainless steel rotor. Water is fed into the PSS Shaft Seal for cooling/lubricating the seal faces on high-speed vessels. The stationary carbon stator is attached to the nitrile bellow, which is attached to the stern tube (shaft log). Rotor The rotor is made out of 316L stainless steel and machined to a 9-12Ra finish on precision CNC lathes. It is secured on the shaft using 2 pairs of set screws positioned at a 90-degree angle for maximum holding power. The stainless steel rotor further polishes the carbon stator during the initial hours of operations.Carbon StatorThe high-density, resin-impregnated carbon stator is manufactured from an advanced composite that is first mixed and molded and then formed under pressure. The blank parts are then baked, machined, and lapped to a measured flatness of 4 helium light bands (measured at 0.000044" of variation over its entire lapped surface). The grade of carbon composite used in the PSS Shaft Seal has a maximum operating temperature of 500°F (+260°C) and cannot melt if the seal runs dry for a short period of time, unlike a lip seal or a plastic face seal. In addition, the high density of the carbon greatly increases longevity and wear resistance. As a result, several commercial vessels have recorded over 40,000 engine hours (over 4 1/2 years of continuous operation) on the same original components.BellowsThe bellows on the Type A seal are molded out of a Nitrile compound. Nitrile is known for its good resistance to petroleum products. In addition, it provides the best combination of durability, strength, and elasticity necessary for this application.Hose BarbFor high-speed vessels (12+ knots), a positive water supply is required to be plumbed to the PSS Shaft Seal for lubricating and cooling the seal faces. Please review the PSS Shaft Seal Installation Instructions for more information on pickup points for water supply. In most cases, a slow-speed boat (less than 12 knots) that does not have a bearing on the shaft log does not require positive water feed and can simply be vented. Ideally, the vent line will be run at least 2-3 feet above the waterline and as close to the centerline as possible. This will ensure the vent hose is never below the water line, even with significant healing. PSS Shaft Seal Installation Instructions have more details on venting the seal.Specifications: Temperature Limits: 5°F to 225°F (-15°C to 107°C) Pressure Limits: 15 PSI (1 BAR) Shaft RPM Limits: 10,000 RPM Carbon Graphite: Lapped to 4 HLB (0.000044" tolerance) 316SS / Nitronic 50: Faced to 9-12 Ra Bellows Material: Molded Nitrile - PVC Shaft Diameter: 45mm Stern Tube Diameter (inch): 3-1/4" to 3-3/8" Approximate Length: 9.2175 in.
