Static Seals

Fixed, Firm and Safe

Static Sealing Solutions for the Food & Beverage Industry

Static sealing solutions are used for applications involving no or only a little movement between the sealing component and the surface. A distinction is made between static axial seals where the sealing occurs parallel to the seal center-line and static radial seals where the seal centerline is in a radial seal orientation.

Hygienic Flange Seals for Customized Flanges

For the food, beverage and pharmaceutical industries Freudenberg Sealing Technologies designs hygienic flange seals for customer-specific sealing grooves. Our tailor-made solutions enable hygienic sealing flush with the product. This means the flange seal neither protrudes into the product area, nor does it rebound.

There is a particularly proven design for special housings in the process industry. Thanks to unique FEM analyses, this offers optimized hygienic sealing in contrast to conventional flange seals. The high-performance flange seal also provides a very easy cleanable solution in non-rotationally symmetric systems and standard housings. The material variants, such as EPDM or HNBR, show high resistance to CIP/SIP cleaning media (cleaning in place/sterilization in place) and meet the requirements of the American FDA (Food and Drug Administration). This makes this sealing solution the ideal candidate for demanding operating conditions in food, beverage and pharmaceutical applications.

The experts at Freudenberg Sealing Technologies also offer advice on the design of the seal groove. After all, with the proper seal groove, the seal can be installed in a way that prevents leakage. Here, it is important to pay attention to a metallic compression limitation and centering. Thanks to the wide range of research and development possibilities at Freudenberg and the company’s extensive product and materials expertise, the respective sealing solution can be tailored to the desired application, including hygienic flange seals.

The Main Benefits for You

  • Optimization of customer-specific, hygienic sealing using the Finite Element Method
  • Resistance to CIP/SIP cleaning media
  • Materials comply with FDA requirements
  • Very easy to clean, even in non-rotationally symmetrical systems and standard housings
