Diaphragm Compressor

Our diaphragm compressor is built on precision-based design methodology, integrating advanced multi-physics simulation and surface treatment technologies. It delivers a domestic-leading outlet pressure of 87.5 MPa and a displacement of 500 Nm³/h at 12 MPa inlet, ensuring reliable, oil-free compression for high-pressure hydrogen applications.

Product  Details
  • This product is an oil-free compressor that achieves gas compression through hydraulic-driven diaphragm reciprocating deformation. The diaphragm completely isolates the hydraulic fluid from the process gas, ensuring contamination-free output. With a modular design, compact structure, and reliable sealing, it is suitable for high-pressure hydrogen and specialty gases. Features include high discharge pressure, stable volumetric efficiency, and long maintenance intervals, making it ideal for hydrogen refueling stations, high-pressure hydrogen storage, and industrial gas compression.
Product Advantages
  • Based on precision design thought, for the first time, the diaphragm compressor overall design and core part design technology are achieved.
  • Breakthroughs in gas-liquid-solid coupling technology, diaphragm surface treatment technology, high pressure hydraulic plunger technology
  • The first in China: outlet pressure 87.5MPa, discharge capacity 500Nm3/ h@12MPa
