Diaphragm Seals

Flanged connection diaphragm seals

When you have to deal with agressive media, a seal provides vital protection to the instrument. The instrument can be directly mounted to the seal and the seal is directly mounted to the process with the flanged connection.

The large variation in available options makes sure there is always a fitting product for you. The material of the flange body is available in many different steels, stainless steels or even titanium! Similarly, the seal can be coated with ECTFE or PFA, or even with Gold!

Furthermore, the flanges we offer are always certified according to international standards and made with the highest care and quality materials.
