D920 Flanged diaphragm seal with flush diaphragm Main Features Pressure range from 25 mbar to 400 bar Flush diaphragm Temperature -40 °C … 400 °C Optimized for assembly with transmitters Class 150 to 2500 NPS 2" to 4" PN10 to PN100 DN50 to DN100 Applications Oil & Gas / Chemical Water / Waste water Energy Process technic Technical Data 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. Only the active part of the diaphragm is made of specific materials. The flange face is always stainless steel. The diaphragm seals D92x have been developed especially for the measurement of low pressure ranges in applications with high overpressure resistance or high static pressure. They are designed for assembly with electronic transmitters for pressure or differential pressure, which can also be used for level or flow measurement. The D92x series cannot be used with pressure gauges. For pressure gauges the series D82x has to be used. The filling fluid of the measuring system has to be choosen compatible to the application.
