0...1 bar__0...40 bar, 0...1 bar__0...25 bar - Diaphragm Seals

Due to their hygienic process connection, the WIKA 990.24 sterile connection diaphragm seals are particularly well suited for food production. With this diaphragm seal, pressure measuring instruments can be integrated, dead-space free, into a pipeline using a VARINLINE® access unit or in tanks using a connecting flange for VARINLINE® access units. The diaphragm seals can withstand the cleaning vapour temperatures occurring in the CIP and SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal. 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. 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 electropolished.

Thanks to its flush process connection, the WIKA 990.17 diaphragm seal is optimally suited for installation in storage tanks. With a suitable welding flange, this diaphragm seal can be integrated into any type of tank or vessel. Level measurement with diaphragm seals also works with media that, due to the process, are under pressure and have high or low viscosity. The WIKA 990.17 diaphragm seal is particularly suitable for CIP cleaning processes as it meets the requirements for elevated temperatures and chemical resistance to cleaning solutions.
