D825 Flanged diaphragm seal with specific materials Main Features Pressure range from 160 mbar to 400 bar Wetted parts in specific materials Temperature -40 °C … 400 °C Class 150 to 2500 NPS 2" to 3" PN10 to PN100 DN50 to DN80 Applications Oil & Gas / Chemical Water / Waste water Energy Process technic Technical Data This diaphragm seals with flanged process connection and specific materials are used to protect pressure gauges from high temperatures, aggressive or corrosive fluids. The diaphragm seals allows direct mounting on standardized flange connections of pipes or tanks. With the flush diaphragm these seals are used especially for fluids with high viscosity or a tendency to crystallize. A wide range of material allows the user to adapt the diaphragm seal to many different type of application and process fluids. Both diaphragm and body (wetted parts) are made completely from the specific material and welded together. A stainless steel counter flange, which is not in contact with the medium, is used to fix the diaphragm seal on the installation. The filling fluid of the measuring system has to be choosen compatible to the application.
