PSS PRO Shaft Seal 2-3/4" Shaft  4" Tube [03-234-400]

Ships Direct From Manufacturer

PRO Shaft Seal 2-3/4" Shaft & 4" Tube

The PSS PRO Shaft Seal is a mechanical face seal utilizing PSS Shaft Seal's proven stainless steel and carbon sealing components but adding reinforced silicone bellows, a 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, the PSS PRO Shaft Seal is a specialized mechanical seal suitable for various applications with unmatched performance.

As with PSS Type A & B Seals, the PRO 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 stationary carbon flange is attached to a heavy-duty silicone bellows attached to the vessel’s stern tube (shaft log) with 316SS hose clamps. The stainless-steel rotor is fitted on the shaft in front of the carbon flange and is used to compress the bellows. The rotor is then secured to the shaft with set screws, and the shaft retention collar is installed. This compression (pre-load) maintains constant contact between the two mating faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable axial movement due to propeller thrust. In addition, the carbon flange is over-bored to the shaft diameter, allowing it to "float" around the shaft and thus compensate for most misalignment and vibration from the drive line. The stainless-steel rotor is sealed to the shaft by two O-rings recessed into the rotor's bore. These O-rings rotate with the shaft and the stainless-steel rotor and therefore do not experience wear during operation.

Components:

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 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.

Rotor

The rotor on the PRO seal is manufactured 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; in addition, a locking collar is placed in front of the rotor and further retains the propeller or rudder shaft in case of catastrophic failure of the coupling or if the shaft comes free from the coupling. As on the Type A seal, the stainless steel rotor further polishes the carbon stator during the initial hours of operation.

Carbon Stator

The high-density resin-impregnated carbon stator is manufactured from an advanced composite that is first mixed, 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, unlike a lip seal or a plastic face seal. In addition, the high density of the carbon greatly increases 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.

Bellows

The bellows on both the PRO and Type B PSS seals are constructed out of high-temperature silicone laminated with either 4 or 5 plies of polyester fabric (aramid in larger sizes) and covered with a layer of fluorosilicone. In addition, both ends of the bellows are sealed so no water can get into the polyester/Aramid fabric. The 4 or 5 fabric inlay provides excellent strength to abrasion and resistance to pressure without loading the silicone. On the larger models, the strength is greatly increased by using stainless steel hoops laid into the convolutions of the bellows.

Hose Barb

For high-speed vessels (planning hulls or vessels powering over 12 knots), it is required that a positive water supply be plumbed to the PSS Shaft Seal for lubricating and cooling the seal faces. There are many water supply sources; review the PSS Shaft Seal Installation Instructions for more information and note that all plumbing must follow the standards and practices of proper boat plumbing. In most cases, a slow-speed boat with no bearing in the shaft log does not require positive water feed and can 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 to ensure the vent hose is never below the water line, even if the boat heels. Again, review the PSS Shaft Seal Installation Instructions for more details on venting the seal.

R  D Flexible Shaft Coupling f/5" B/W, Hurth,  Volvo - 25HP/100RPM Capacity [910-057]

Flexible Shaft Coupling for 5" B/W, Hurth, & Volvo - 25HP/100RPM Capacity

The R & D Marine Flexible Coupling consists of a flexible disc molded with a polyester elastomer. The disc gives clearance for bolt heads and is able to flex freely to take up any temporary misalignment of the engine and shaft due to flexing of the boat structure or the engine moving on its mount. Forward thrust is taken in compression on the disc between the two half couplings, and reverse thrust is retaken in compression on the disc between the two fail-safe straps. In the unlikely event of a severe impact, the steel straps make the coupling fail-safe and ensure the drive is maintained both forward and reverse.

Reduce Engine Noise & Transmission Vibration

Staggered bolts enable the element to isolate vibrations and compensate for some misalignment.

Reduces Costly Transmission Repairs

Absorbs shock loads due to hard gear changes.

Fits Most Major Transmissions

For engines, 5 to 1,500 horsepower It fits brands such as Borg Warner, ZF-Hurth, Twin Disc, Volvo, Yanmar, Technodrive, and more.

Under Compression Load In Both Forward & Reverse

The aft steel strap bolted to the transmission acts as a backing plate to prevent reverse thrust from pulling the element apart.

Quick & Easy Installation

The R & D Marine Flexible Coupling requires no machining and comes supplied with bolts to connect between the two existing shaft flanges.

Extremely Durable

Impervious to saltwater, diesel, and lubrication oils. The Flexible Couplings are made from a polyester elastomer not affected by saltwater, diesel, or lubrication fluids.

Fail-Safe Design

A fail-safe design is incorporated in the R & D Flexible Shaft Coupling that prevents the two couplings from pulling apart in the event of an impact or element failure, whereas other couplings do not. This fail-safe design is accomplished by using two steel straps and thru-bolts going into both the shaft coupling and transmission output flange. The aft steel strap is bolted to the transmission output flange, and the front strap is bolted to the shaft coupling. In the event of an impact, the aft steel strap (bolted to the transmission) will catch the front steel strap (bolted to the shaft coupling) and prevent the drivetrain from pulling apart.

The R & D element will absorb the shock load (reducing or eliminating damage to the transmission) and will maintain contact between the two couplings. The steel straps also keep the R & D Flex-Coupling under a compression load in both forward and reverse operation (the aft strap bolted to the transmission acts as a backing plate).

Machined Not Molded

The Drivesaver is molded, while the R & D Flexible Shaft Coupling is machined. Both designs suggested that you first set your alignment by drawing the two couplings up to each other and then adding the flex-coupling. The machined part will have MUCH tighter tolerance than a molded part.

Checking Alignment

The R & D Flexible Shaft Coupling allows for alignment inspection after the element is bolted in place. There is one bolt head that is machined and painted red. After the R & D Flexible Shaft Coupling is bolted into place, a feeler gauge can be slipped between the red bolt head and the coupling. This process is repeated with the same bolt four times at 90-degree intervals by rotating the shaft. If the gap is within .010" (0.25mm), the engine is accurately aligned.

To calculate the power of the coupling required:

Horse Power of Engine x Reduction Ratio x 100 = HP/100RPM
      Engine Speed  

Example:

• Ford 150 HP at 2500 RPM with Borg Warner Velvet Drive 72C 2:1 Reduction Ratio
• Engine Horse Power is 150 HP, Max Rated RPM is 2500, Reduction Ratio is 2:1
• 150/2500 x 2 x 100 = 12 HP per 100RPM

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.

Rotor

The 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 Stator

The 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.

Bellow

The 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 45mm Shaft  3-1/4" Tube [02-45M-314]

Shaft Seal 45mm Shaft & 3-1/4" Tube

This 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?

1. Two nitrile o-rings seal the stainless steel rotor to the shaft and will not experience wear.
2. A primary set screw and a backup set screw (2 sets) are used to secure the stainless steel rotor to the shaft.
3. A seal is created between the two flat surfaces of the carbon stator and the stainless steel rotor.
4. Water is fed into the PSS Shaft Seal for cooling/lubricating the seal faces on high-speed vessels.
5. 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 Stator

The 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.

Bellows

The 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 Barb

For 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.
