NEW
VR Low Friction Seal
Maximum performance. Minimal friction.
Our latest sealing solution sets new standards in sealing technology.
It combines the best properties of elastomers and PTFE. Resulting in?
A pressure-resistant and energy-efficient rotary shaft seal. The flexibility
of the high-quality elastomer ensures optimum adaptation, while the
PTFE diaphragm significantly reduces friction. This means maximum
efficiency and durability for your applications.
Advantages
- Friction minimisation approx. 50-70 % (depending on the friction condition) compared to standard VR seals
- Low heat generation
- Therefore also suitable for sensitive foodstuffs in fast-rotating pipes (hollow shafts)
- Greatly improved dry-running properties
- Leakage minimisation
- Stiffer sealing lip for easier installation
- Increased circumferential speed permitted
- Safe use in difficult lubrication conditions
- Can minimise noise at sealing points, for example when using EPDM.
- Sustainable, as minimised use of PFAS materials possibile
Applications
- compressors
- Rotary feedthroughs
- i.e. For compressed air
- For vacuum
- high performance pumps
- high performance fans
- when too much heat is an issue
- Perhaps your application too, please contact us!
