Typical applications include cylinder filling, fuel cell technology, or transfer of high purity or dangerous gases under pressure - without contamination or leakage. Our sealless diaphragm compressors and hydrogen compressors include laboratory and production scale models, single and multi-stage packages with displacements to 400 cfm (680 m3/hr) and pressures to 30,000 psi (2,000 bar). A variety of head closure designs, power-frames, accessories, and materials of construction that accord Sundyne PPI to match a diaphragm compressor to most industry process parameters.
