D055 Flush diaphragm seal with screwed process connection Main Features Wetted parts stainless steel 1.4404 (316L) Flush diaphragm Compact design Applications Laboratory & Medical Oil & Gas / Chemical Water & Waste water Energy Transportation & Logistics Machinery Description This chemical seals with threaded process connection are used to protect pressure gauges from high temperatures, aggressive or corrosive fluids. Pressure ranges 0 ... 1 bar to 0 ... 600 bar (see table below) Body material Stainless Steel 1.4404 (AISI 316L) With the flush diaphragm these seals are used especially for fluids with high viscosity or a tendency to crystallize. They avoid that the medium flows into the instrument, where desposits could be built and generate wrong measurements or pollution of the process. Diaphragm Stainless Steel 1.4404 (AISI 316L) Working temperature -60…200°C (depending on the filling fluid) Filling fluids Chemical seals can be mounted to mechanical pressure gauges, switches or transmitters directly or with a cooling element. The filling fluid of the measuring system has to be choosen compatible to the application. LRS1 (vaseline : -15 ... +150°C) LRS2 (silicone DC510 : -60 ... +150°C) LRS3 (silicone DC550 : -20 ... +200°C) Minimum pressure ranges 1) Pressure gauges P max.
