Piston gas compressor 2GM4-27/9

M4-based opposition piston crosshead compressor 2GM4-27/9 with cylinder and gland lubrication for compression and transfer of various gases and gas mixtures used for technical purposes in industry. The complete compressor unit consists of a compressor, refrigerators (gas coolers), gas pipework, cooling and automation systems. The compressor is a piston crosshead machine with opposing cylinder arrangement.

The compressor design is based on the normal range of machines adopted at Krasnodar Compressor Plant. For separation of liquid and oil particles there are cavities in coolers or moisture and oil separators, from where condensate and oil are removed by periodic blowing. The compressor is driven by an in-built electric motor, the motor stator is attached to the frame lantern and the rotor is mounted on the compressor crankshaft shank.
