Mini Diaphragm Seal Model 8203

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 flush diaphragm seal with threaded process connection can be used for corrosive and hot media and also poisonous fluid which is dangerous for environments. The compact design makes Seal-Mate 8203 to be in the category of mini diaphragm seals which are suitable for  applications with frequent maintenance.
