Sanitary Diaphragm Seal Model 8212

Seal-Mate group of diaphragm seals come between the pressure measuring instrument and some media which can damage the instrument or be harmful if they get directly in touch with the instrument. In many industrial processes, it happens a lot that the media cannot or should not get into direct contact with the instrument. Sometimes that is for the sake of keeping the instrument work properly as the media is too viscous and might easily clog the process connections, and sometimes it is for hygienic purposes.

The flexible metal diaphragm of Instrumate seals is made of SS316L by default and the space between this flexible diaphragm and the instrument process connection is filled with a filling fluid, chosen in best interest of where the instrument is going to be installed. So the intended pressure is transmitted via the flexible diaphragm to the filling fluid and then via the filling fluid to the pressure instrument.

Instrumate diaphragm seals are vacuum protected and also not sensitive to sudden sharp increase in pressure.

Instrumate sanitary diaphragm seal Model 8212 is specially designed to endure high steam temperatures for sterilization of the process connection. Instrumate 8212 joins with pipe connection via a union nut available is all standard sizes. If hygienic feature is going to be maintained in food or pharmaceutical industry, then Instrumate 8212 is a great choice because of its fast and easy removal from the plant.
