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.

What are diaphragm seals?

Diaphragm seals, also known as remote seals or chemical seals, basically have two tasks. Firstly, they separate the measuring device from the medium and secondly, they transfer the pressure to the measuring device and can be disassembled very easily and quickly for cleaning and calibration purposes.

When should you use diaphragm seals?

They are typically used in application areas where the process medium should not come into contact with the pressurised parts of the measuring instrument. This protects the measuring instrument and extends its service life.

In which sectors are sanitary diaphragm seals mainly used?

Sanitary diaphragm seals are used primarily in industries that require a high level of sanitation. For example, in the pharmaceutical and beverage industries as well as in the water purification industry. Sanitation-conscious manufacturers gain a high level of safety and efficiency by using WIKA measuring instruments that are equipped with sanitary diaphragm seals.To achieve the required degree of purity in these areas, high temperatures and various chemicals are used in sterile or sanitary facilities. A diaphragm seal is therefore required in this environment to protect the measuring device and helps to extend its service life.
