Compressor D-Style

D-Style Compressors


D-Style compressors are extremely versatile. They can be used to transfer liquids between tanks, off-load/load out liquids, recover residual vapor, pressure boosting, gas blanketing, gas gathering, evacuate vapors for maintenance purposes, etc.


Corken offers a broad range of models and corresponding piston displacements. The oil-free units range from 4 to 60 cfm (6.8-102 m3/hr) and the double acting versions are capable of between 50-100 cfm (100-171m3/hr). Depending on the compression ratio, Corken provides either single- or two-stage compressors for efficient gas compression.

Corken offers a variety of piston rod packing configurations, distance piece options, and special coatings suitable for a wide range of industrial gases. A double packed (D-Style) reciprocating compressor has one distance piece and offers a moderate level of leakage containment. A triple packed (T-Style) compressor has two distance pieces offering the highest level of leakage control.

If necessary each area between the packing area can be purged/pad for maximum leakage containment. Both styles are available in single- and two-stage, air or water cooled, and single and double-acting versions with NPT or Class 300 RF connections.

Standard compressor mountings designed for liquefied gas transfer, vapor recovery, and gas booster applications are available. If one of these do not meet the requirements of the application, Corken can supply a custom engineered package. The ASME B31.3 – 2012 piping option is available upon request.
