D820 Flanged diaphragm seal with flush diaphragm Main Features Pressure range from 160 mbar to 400 bar Flush diaphragm Temperature -40°C ….400°C Class 150 to 2500 NPS 1"1/4 to 4" PN10 to PN100 DN25 to DN100 Applications Oil & Gas / Chemical Water / Waste water Energy Process technic Technical Data This diaphragm seals with flanged process connection and flush diaphragm are used to protect pressure gauges from high temperatures, aggressive or corrosive fluids. The flush diaphragm 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. Different diaphragm materials can be selected to adapt the seal to various applications and process fluids.

EN1092-1 : PN 10 to 100, DN 25 to 100. Available flange faces see table on page 3. Other flange types on request. Stainless steel 1.4435 (AISI 316L) Option: Hastelloy, Uranus (see ordering details on page 4) The diaphragm seals can be mounted to pressure gauges or pressure switches directly or with a flexible capillary. For use with electronic transmitters for pressure and differential pressure the product series D9xx is recommended. The filling fluid of the measuring system has to be choosen compatible to the application.
