Diaphragm seals

The optimal diaphragm seal for every process

WIKA diaphragm seals (often also referred to as chemical seals), mounted with pressure gauges, process transmitters, pressure switches etc., are recognised and valued internationally for the most difficult of measuring tasks. By using diaphragm seals, the measuring instruments can be used at extreme temperatures from -90 to +400 °C and with aggressive, corrosive, heterogeneous, abrasive, highly viscous or toxic media. The optimal diaphragm seal designs, materials and filling media are available for each application.
