VR Low Friction Seal
The new, optimized VR sealing lip ZK (patent pending) combines the positive properties of elastomers and PTFE. The flexibility of the seal is ensured by the elastomer used and the greatly improved frictional properties of the PTFE membrane, which is firmly bonded to the elastomer membrane.

Successful customer projects
Rotary feedthrough for air and vacuum / Example laser rubber cutting system
For more precise process control, it was necessary to feed both compressed air and vacuum into a rotating device. Ideally, this should be done via a common channel. In addition, the available torque was considerably limited due to a power transmission using a magnetic coupling.
The VR SAC seal proved to be the optimum solution due to its 2 opposing sealing lips and its energy efficiency.

Modern food processing machines
VR seals are used in machines for food production, especially when conventional rotary shaft seals cause too much friction, smooth surfaces are required or the service life of the current seal is insufficient. Thanks to modern materials, a wide range of applications can be realized.

Questions and answers
How high is the investment for an individually developed sealing ring?
The needs of each company and each machine are different, so prices can vary greatly depending on the work involved. It is therefore highly recommended that you arrange a non-binding consultation.
Where is the plant located?
What is the usual procedure for VR seals?
We advise the customer on technical queries. If our product is suitable, we will prepare a non-binding offer and, if it is a standard seal, provide a sample.
Commercial inquiries are processed according to the usual processes. The fact that we can produce in very small quantities means that our customers only have to accept low minimum order quantities.
What do I do if I need my individual product again after it has worn out?
Simply read the size from the seal, take it from the parts list or measure it and send an e-mail to sales@vr-dichtungen.com. You will receive an offer within 24 hours.
