Design and material

The MVR seals are made of a nitrile rubber material with very good wear resistance. Other elastomers are also available on request.
The standard metal element is zinc-plated cold-rolled carbon steel. Acid-resistant steel, similar to SAE 316, is available on request.
There are two different MVR seal designs: the basic MVR1 seal and the MVR2 seal with case extension (fig 1).
