Piston Compressor for 30 MPa at the Maximum

Because of the bad lubricity of gases, piston compressors have to be either supphed with lubricating oil or fit for dry running. As the extraction of the oil out of the gas stream is essential after the compressor step, oil traps are arranged subsequently. 

ECTFE with good sliding properties. This section is followed by a lantern ring that is used for purging and therefore, in a way, for lubrication and cooling of the piston. Next to this is placed a series of low-compression seals. The piston is hardened and characteristically lean for the accomplished pressure level in order to keep the driving forces low.
