hese compressors are designed to cover a wide range of applications and pressures (hydrogen mixtures, hazardous gases, high pressure). Casings can be rolled steel or forged with one or two end covers bolted or secured by shear rings.
For improved performance, diaphragms are mostly machined.
Radial and thrust bearings are of the tilting pad type.
End seals are of the dry gas type. Other sealing solutions are also available.
In addition to conventional labyrinths, inter- stage seals can be abradable or honeycomb seals to optimize the overall performance of the machine.
In-line, back-to-back or double flow configurations are also available.
Materials are adapted to the process requirements. Based upon extensive experience in corrosive applications, specific materials are selected to withstand the various forms of corrosion present in sour or acid gas applications.
