For sanitary applications, NEUMO BioConnect®
Description
Diaphragm seals are used to protect the pressure measuring instrument from aggressive, adhesive, crystallising, corrosive, highly viscous, environmentally hazardous or toxic media. A diaphragm made of the appropriate material provides for the separation from the medium to be measured. Thus even the most difficult measuring requirements can be met by combining measuring instruments with diaphragm seals.
A fluid inside the system, which can be chosen to suit the particular application, hydraulically transmits the pressure to the measuring instrument.
Almost limitless application possibilities exist due to the large number of available variants, such as diaphragm seal designs or materials. The type of process connection (flange, threaded and sterile connection) and the basic method of manufacture are important design differentiation criteria.
For further technical information on diaphragm seals and diaphragm seal systems see IN 00.06 "Application, operating principle, designs".
The model 990.50 NEUMO BioConnect® diaphragm seal is ideally suited to fulfil the high standard requirements of sanitary applications. It can be optimally integratedinto pipelines via the BioConnect® fittings, fulfils all hygienic design requirements and is EHEDG certified. The diaphragm seal systems can withstand the cleaning vapourtemperatures 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.
