Diaphragm compressors up to 1,000 bar Oil- and contamination-free compression No gas losses (free from leakages) Type examination in accordance with ATEX Complete systems High operational and process reliability Low noise level Corrosion resistant special steel design sera Product Solutions The state-of-the-art compressor for the industry

Functions – Models – Performance overview 2 Functions The stroke movement of the piston is transmitted through a hydraulic fluid to the multi-layer metal diaphragm. It ensures that gas can’t escape to the outside and that there is no contact with the hydraulic fluid. Important machine parameters such as oil pressure and condition of the diaphragm are continuously monitored. All sera diaphragm compressors are designed for industrial continuous operation. Models n Vertical construction; type series MV 1 to MV 4; single-, two- or three-stage n Horizontal construction; type series MV 5 single-, two-...

3 Application examples n Chemical, petro-chemical and pharmaceutical systems n Hydrogen and natural gas fuel stations n Gas filling systems n Recovery and treatment plants n Research and pilot plants Diaphragm compressor in hydrogen filling station The two-stage sera diaphragm compressor compresses the hydrogen coming from the H2 source to a buffer pressure which is approx. 100-150 bar higher than the corresponding filling pressure. The filling pressure is 350 or 700 bar, depending on the application. The diaphragm compressor is integrated in the control concept of the overall system. Compressor...
