Compressors for compression of natural and associated petroleum gas

These compressors are designed for compression of natural and casing-head gas. The compressors are of reciprocating type on opposite bases 2M2.5; 4M2.5; 2M4; 2M10; 4M10 and 6M25.

The reciprocating mechanism is lubricated by oil circulated under pressure being produced by gear-type pump. The cylinders and rod sealing devices are forced lubricated under pressure being produced by multi-plunger pump. The cylinders are forced cooled by fluid through closed loop. Intra stages the gas is cooled by water through closed loop discharged under pressure.

Automatic monitoring, control and protection system ensures monitoring of main parameters, alarm and emergency signaling as well as blocking of driving electric motor.
