The 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 stationary carbon flange is attached to the front side of the bellow with hose clamps, and the back end of the bellow fits over the Stern tube and is secured with hose clamps. The stainless-steel rotor is fit on the shaft in front of the carbon flange. The stainless-steel rotor is used to compress the bellow before the rotor is secured to the shaft with set-screws. This compression (pre-load) maintains constant contact between the two flat faces of the stainless-steel rotor and carbon flange, allowing the PSS to compensate for the variable fore and aft movement due to propeller thrust. 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 problems. The stainless-steel rotor is sealed to the shaft by two O-rings that are recessed into the bore of the collar. These O-rings rotate with the shaft and stainless-steel rotor and do not experience wear during operation.

How Does It Work?

How a PSS Type A Shaft Seal Works

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).

Components

PSS Type A Shaft Seal rotor

Rotor

The PSS stainless steel rotor is slid down the shaft and is 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 are made from 316L stainless steel.


Carbon Stator

The high density, resin impregnated carbon/graphite stator is a space age 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 entire lapped surface). The grade of carbon used in the PSS has an operating temperature 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 the 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.

PSS Type A Shaft Seal bellow

Bellow

The PSS Type A Shaft Seal bellow is made from rubber (Nitrile), and has a temperature rating of -25°F to +225°F (-31°C to +107°C). Nitrile is known for its good resistance to weathering. Nitrile rubber's single most important property is its exceptional resistance to oils and non-polar solvents. It also offers good gas impermeability, abrasion resistance and better thermal stability than most general purpose elastomers.


Hose Barb

For high speed vessels it is required that a positive water supply be plumbed to the PSS Shaft Seal for the purpose of lubricating and cooling the seal faces. There are many sources of water supply, review the PSS Shaft Seal Installation Instructions for more information and note all plumbing must follow the standards and practices of proper boat plumbing. In most cases a slow speed boat that does not have a bearing 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 water line and is close to the center line as possible to ensure the vent hose is never below the water line, even if the boat heels. Review the PSS Shaft Seal Installation Instructions for more details on venting the seal.

PSS Maintenance Kit

Typically the carbon and stainless steel sealing components will not need replaced where we see many commercial vessels recording over 40,000 engine hours on original components. That said, we do recommend the rubber bellow component be replaced in 6 year intervals as precautionary maintenance kit for this replacement which includes the rubber bellow and all necessary hardware.

New and used set screws

Set Screws

Please be sure to never use the same set screw on the shaft twice. There are two set screws in each of the two holes in the stainless steel rotor. One is tightened onto the shaft and the other is tightened onto the first to lock it in place against the shaft. The set screws are made with a cup at the base that compresses into the shaft ensuring a secure grip. When re-installing the rotor please use new set screws. In the case that you do not have spare set screws, the set screws in the rotor need to be reversed so there is an unused cup being compressed onto the shaft.

If you need to new set screws you can purchase a PSS O-Ring Kit. This comes with 2 new o-rings, 5 set screws, an allen wrench, Clamp Jackets and Thread Lock.
