Standard Parts of the “Hygienic Design” product family are labeled with the HD icon. They combine high surface quality, freedom from dead spaces, non-scooped outer surfaces, and sealed bolting areas. A sealing concept based on FEM calculations ensures reliable contact pressure after installation.
Components with cylindrical mounting surfaces, which are installed in hygienic areas, can be sealed and mounted without dead spaces using sealing rings GN 7600. Standard parts that are supplied with sealing rings GN 7600 are listed in the table and can be supplied individually in case service is required.
When delivered, or when not assembled, the sealing rings have the “actual dimensions” stated in the table. To ensure a firm seating and a reliable sealing, an installation space as shown in the sketch must be provided on the component. This ensures that when the sealing ring is mounted, it will be subject to the necessary pressure without excess load. All surfaces that are in contact with the sealing ring should have a minimum surface quality of Ra 0.8 µm.
