The diaphragm compressor has a hydraulic piston system with tight sealing so that ionic fluid can‘t mix with the gases.
A reciprocating piston-crankshaft system drives the oscillating diaphragms. Only the diaphragm for the process and the compressor process head are in contact with gas. The diaphragms are important, as they prevent hydraulic fluid or oil from the compressor from contacting the gas. It eliminates the possibility of contamination, which is important for Hydrogen applications because the purity has a direct effect on the process. Diaphragm compressors can also be used to pump toxic or explosive gasses. The diaphragm should be durable enough to resist fatigue, while also possessing adequate chemical properties that will prevent corrosion.
