The PSS PRO shaft seal is a mechanical face seal using PSS's proven stainless steel and carbon sealing components. , with some additions. These additions include the addition of a reinforced silicone bellows, 316 stainless steel hose clamps (rolled, non-perforated edges), and an optional Nitronic 50 rotor upgrade (for highly corrosive environments). /p>

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 delivers unmatched performance.

Features:

2-inch shaft diameter
Tube diameter stern length from 2-3/4" to 2-7/8"

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 wear out.

The retention collar Shaft is attached to the shaft and helps retain the propeller or rudder shaft in a vessel in the event of a catastrophic failure of the coupling or if the shaft becomes detached from the coupling.

A seal is created between the two contact faces of the carbon stator and the stainless steel rotor.

Raw water is introduced into the PSS shaft seal for cooling/lubrication. the joint faces on high-speed ships.

Clamp tail protection, clamp jackets.

The fixed carbon stator is attached to the bellows, which is fixed to the tin tubebot (tree log).

316SS tree clamps with rolled edges and non-perforated band.

Tree retention collar

The PYI Shaft Retention Collar The collar is designed to help retain the propeller or rudder shaft in a vessel in the event of a catastrophic failure of the coupling or if the shaft becomes detached from the coupling. The double slot design provides maximum axial holding power with the benefit of quick and efficient assembly with the installed shaft. The design fully engages the tree without spoiling it. Easily installed where major disassembly would otherwise be required. Greater axial holding power than set screws or one-piece clamps. Effective on hard and soft shafts.

Rotor

The PSS stainless steel rotor is slid along the shaft and secured to the shaft with 90° adjustment screws 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 any run-out when the collar rotates. The carbon graphite stator will polish the rotor face 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 Type A PSS shaft seal is made of 316L stainless steel.

Carbon stator

Carbon impregnated with high density resin Graphite stator is a composite that is first mixed, molded, and then formed under pressure. The blanks are then cooked, machined and lapped. The face of our carbon is finished with a flatness of 4 helium light strips (measured 0.000044" variation across the entire lapped surface). The grade of carbon used in PSS has a working temperaturetemperature over 500° Fahrenheit (+260° Celsius) and cannot melt if the seal dries, unlike a rubber lip seal or plastic face seal. The high density of carbon considerably increases its longevity and resistance to wear. Several commercial vessels have recorded more than 40,000 (over 4 and a half years). continuous operation) engine hours on the same original components. The carbon should not need to be replaced under normal operating conditions.

Bellows

The PSS PRO Shaft Seal Bellows provides best combination of durability, strength and elasticity. It is made of four-ply aramid or silicone with a fluorosilicone exterior. This fluorosilicone coating creates an oil and fuel resistant barrier, protecting the exterior surface from the possibility of damage from a splash or spill. Both extremoved from the bellows are sealed. The four-ply fabric inlay provides excellent strength and abrasion resistance. This bellows has a continuous operating temperature range of -90°F to +425°F (-70°C to +220°C).
