Metal Diaphragm Compressor sera - Metal diaphragm compressors are oscillating diaphragm compressors - the solution to the dirt- and oil-free compression of gases. Compression of gases with inflamma- ble, aggressive, inert, toxic and ra- dioactive properties. • oil-free compression • pollution-free compression • robust with long service life • high quality materials • controllable flow space-saving design • with type approval acc. to ATEX • no pressure relief needed for This leaflet is only a general meet your specific requirements!

Metal Diaphragm Compressor The piston travel is transferred through the hydraulic fluid to the metal diaphragm. The multi-layer diaph- ragm fully contacts the valve head at the end of the pressure stroke, and against the perforated plate at the end of the suction stroke. A compensation pump and pressure regulating valve ensure optimum hy- draulic fluid volume between the piston and diaph- ragm. The compressor is driven with the help of an electric motor. The compensation pump is driven by the compressor crankshaft. Suction and pressure valves open and close the diaphragm in rhythm with Metal...
