Hygienic and Aseptic Seals – Keeping your process integrity at all time

The solution for controlled and reliable sealing of rotating movements with an absolute protection of (valuable) product, people and the environment. The dead-space free construction can be cleaned from the internal part of the seal by means of CIP and / or SIP. It is also possible to provide the seal with a sterile barrier for use in high-care aseptic and pharmaceutical applications. The condition of the seal can be carefully checked and monitored during its lifetime. A compressed air or barrier-gas signal reports the integrity "health" of the seal. This makes it possible to accurately monitor 24/7 the seal integrity and predict maintenance. No complex and costly subsystems are required, as is customary with traditional mechanical seal systems.


Application areas include process installations and machines where a rotating movement must be reliable, product-friendly and optimally sealed used in the following industries;

• Beer and soft drinks industry    • Food industry    • Pharmaceutical industry

Working principle






The CIP / SIP connection is connected to a controlled branch of the CIP / SIP main line and runs along
with the normal cleaning process. Seal is hereby cleaned both internally and externally. By means of the
compressed air or barrier-gas control signal it is possible to check the integrity "health" of the seal 24/7.

If desired, it is possible to set a predefined alert status, being:

  • Low alarm - Warning starting leak
  • Medium alarm - Warning maintenance upcoming
  • High alarm - Warning requires immediate maintenance
