The WIKA 990.50 NEUMO BioConnect® diaphragm seal is ideally suited to fulfil the high standard requirements of sanitary applications. It can be optimally integrated into pipelines via the BioConnect® fittings, meets all hygienic design requirements and is EHEDG certified. The diaphragm seal systems can withstand the cleaning vapour temperatures occurring in the SIP processes and thus ensure a sterile connection between the medium to be measured and the diaphragm seal.
Assembly of the diaphragm seal and measuring instrument is made via a direct assembly as standard or optionally via a cooling element or a flexible capillary.
For the material selection, WIKA offers a variety of solutions, in which the upper body and the diaphragm are made of identical materials. Stainless steel 316L (1.4435) is used as standard material. Other special materials are available on request.
Measuring systems with the WIKA 990.50 WIKA diaphragm seal are successfully used in the life science industry, in pharmaceutical and biotechnology applications.
