Project Description
- Design with CIP-/SIP (Cleaning in
Place, Sterilization in Place) - Smooth construction of surfaces with
no empty crevices - Sterile application design available
 - Rugged design to ensure long term
reliability and operating life - Seals are assembled in cartridge
construction for easy fitment - Over all connecting dimensions are
tailor made to customer’s
specifications
