The WIKA 990.23 diaphragm seal has been developed for use in pulp manufacture or waste-paper processing applications.

Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling element or via a flexible capillary. Optionally, there are pipe elbows and vibration dampers available.

For the material selection, WIKA offers a variety of solutions, in which the upper body of the diaphragm seal and the wetted parts can be made of identical or different materials. The wetted parts can, as an alternative, be coated.
