FKW Compressor's diaphragm compressor for sale is a positive displacement compressor with a special structure. As its cylinder requires no lubrication, has excellent sealing performance, and the compressed medium does not come into contact with any lubricant, our diaphragm compressors for sale can compress gases with extremely high purity, generally reaching 99.999%. Due to their "zero pollution" and "zero leakage" characteristics, diaphragm compressors play a crucial role in the development of hydrogen energy. The maximum displacement can reach 4000 Nm³/h, and the compressor piston force can reach 250 kN. As a professional gas compressor factory, FKW Compressor has successfully introduced 90 MPa high-pressure, 250 MPa, and 320 MPa ultra-high-pressure diaphragm compressors, addressing critical challenges in domestic substitution and core bottleneck technologies across national key sectors. These technological breakthroughs have overcome major technical obstacles that persisted for over 30 years, significantly enhanced the security and reliability of strategic industries, and established new benchmarks in high-pressure compression technology.
