Many liquefied gas piping systems do not provide ideal net positive suction head (NPSH) conditions for liquid pumps. As a result the poor NPSH conditions lead to excessive pump maintenance. Since reciprocating gas compressors are only exposed to vapors, they are not affected by poor NPSH conditions. Many liquefied gas pressurized tanks such as tank cars and buried tanks have top unloading connections. A reciprocating compressor is the perfect solution for transferring liquids to and from tanks of this type as well as vapor recovery.
Corken offers a variety of piston rod packing configurations, distance piece options, and oil-free gas compression for wide range of industrial gases. The D-Style is a double packed reciprocating compressor that has one distance piece and offers a high level of leakage containment. However, our T-Style design is a triple packed compressor that has two distance pieces that offer the highest level of leakage containment for today's industrial gases. Depending on the needs of your application, each distance piece can be pressurized, purged, or vented. Both styles are available in single- and two-stage, air or water cooled, and single and double-acting versions. Lubricated and non-lubricated versions are also available.
