Diaphragm Seals

Seals and the wetted parts can be manufactured from different materials considering the kind of process medium or the type of application. The seal will separate the instrument from the process medium. The pressure will be transmitted without any time delay from the seal membrane to the measuring instrument using a transmission fluid.

Schmierer-Seals are manufactured with highest quality standard, also custom-made, and will run through several test cycles on tightness and shape of the surface.

The seal and the system filling fluid (transmission fluid) will be selected and manufactured considering the application, special mounting position, temperature, pressure situation and hygienic/sanitary procedures. Schmierer manufactures a broad range of diaphragm seals for all kind of applications.
