Mink AD-System (AD) – the innovative solution for sealing shafts
The Mink AD-System consists of a specially designed brush ring to seal shafts and to prevent coolants, swarf and mists from escaping. In addition the barrier effect created by the flexible bristles prevents the spread of lubricants, for example.
Three different ring sizes enable fitting to shaft diameters ranging from 10mm to 100mm.
The brush ring and the bristles are made from black nylon which has good resistance to chemicals and is suitable for a wide temperature range from - 40 to + 80°C.
Benefits:
• A flexible sealing also when oscillation or vibration occurs
• A reliable barrier is created
• Three fixing holes enable an immediate and quick assembly
• Quick delivery, attractive prices

The requirement for low coefficients of friction, less than .08, temperatures ranging from -300F to +550F, pressures in excess of 5000 psi, the need to seal a corrosive acid .....These are the typical kinds of factors that tell you that an elastomeric seal probably wont fit your application.
Seal Science Teflon® Seals and Seal Science Perflex perfluoroelastomer are often the answer. Possibly something as simple as a Teflon O-Ring, or a Teflon compound cap to protect the elastomer will do. Or maybe, spring energized Teflon U-Cups, like those in our Polyspring line might be needed. Many of the possible solutions can be found in our Polyking catalog. Whatever the appropriate choice may be, our Teflon engineers will be able to quickly offer you a recommendation and a quote. Check our how competitive we can be!

The PSS Shaft Seal, manufactured for 25 years, uses the well-known system of mechanical seal in order to assure complete water tightness between the propeller shaft and the boat, unlike other brand which uses either a lip seal or a packing gland.
Because of its choice of material, the PSS Shaft Seal can operate in all kind of environment, including salty/sandy waters. Also unlike other type of seals there is no contact, therefore no wear, between the sealing surface and the shaft.
All these qualities make the PSS Shaft Seal the most common brand of Shaft Seals found on the pleasure boat industry today.
Less known is the fact that the PSS Shaft Seals are also very common on all type of work boats (Small ferries, crew boats, fishing boats, coast guards, tugs etc...) as these seals are manufactured for shafts up to 200mm. One huge advantage of these seals on a commercial boat is the lack of maintenance required added to the fact that these seal do not wear the shaft down.
The PSS is approved by RINA, VERITAS, and ABS.

HIRSCHMANN Axial Shaft Seals have a sealing effect on any hardened and sealed mating surface. Therefore there is no shaft wear. The sealing lip is of tapered design in order to keep friction, heatup and wear at a minimum.
Available for sealing dimensions of 6mm to 380mm, in Perbunan and Viton® fluoroelastomers.
Features:
* Minimum friction
* Minimum heat-up
* Minimum space requirement
* Easy installation
* High head resistance
* High chemical resistance
* High rubbing speed
* Long life

An element forms a sealing function when it prevents the passage of a fluid from a one enclosure to another. Such elements are called "Seals".
If the object is to prevent the flow of a fluid from an enclosure into a neighbouring enclosure, the seal is called a Single Seal. If the seal must prevent the flow of another fluid which may be in the second enclosure into the first, the seal is called a double seal.
If the two mechanical parts between which the leakage is likely to occur are fixed with relation to each other, the seal is called static seal. If one or both of these parts is moving relative to the other, the seal is called a dynamic seal.

The new generation of GFD-rotary shaft lip seals were especially developed for use under difficult and extreme conditions.
The superior properties of PTFE as lip material combined with a corrosion resistant stainless steel housing provide the particular advantages of these GFD-rotary shaft seals.
Advantages and applications:
- Temperature range from -70°C to +260°C
- Lowest friction and power draw
- Long seal life because of wear resistant lip materials
- Almost universal chemical resistance (depending on lip material)
- Suitable for dry running and poorly lubricated conditions
- High shaft speed up to 36 m/s
- Exchangeable with standard lip seals according to DIN 3760
- For food or pharmaceutical industry
Applications:
- Chemical processing equipment
- Hydraulic motors
- Compressors
- Shafts on gearboxes
- Rotary
- Blowers
- Ventilators
- Actuators
- Rotary unions
- Encoders
- Mixers and Dryers
- Robotics
