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.

Our industrial compressors are compatible with a wide variety of hazardous, volatile, toxic, and corrosive gases such as chlorine, vinyl chloride, methyl chloride, sulfur dioxide, butadiene, hydrogen, helium and many more. Each compresssor is available with a standard mounting or we can custom engineer a compressor package for you. We now offer an ASME B31.3 – 2012 piping option for all of our compressor packages and skids.

Each product group below is designed for a specific level of leakage containment. To find a compression solution for your application, select one of the product groups listed below.

D-Style Oil-Free Reciprocating Compressor

  • D-style vertical compressors utilize two sets of V-ring packing per piston rod and one (single) distance piece
  • The lower packing set has an adjustable packing screw used to maintain the sealing performance over the life of the packing
  • With the exception of models D791 and D891, all D-Style compressors deliver oil-free gas compression
  • Typically used in toxic and corrosive applications where oil-free gas is required and leakage containment is desirable

Operating Specifications

  • Piston displacements up to 117 cfm (198.8 m3/hr)
  • Working pressures up to 1,200 psi (82.8 bar g)
  • Brake horsepowers up to 45 hp (34 kW)
  • Maximum outlet temperature: 350 °F (177 °C)
