Compressors are extremely versatile for they can be used to transfer liquids between tanks, off-load/load out liquids, recover residual vapor, and evacuate vapors for maintenance purposes. Many LPG piping systems do not provide ideal NPSH conditions for liquid pumps which causes excessive pump maintenance. Since compressors are only exposed to vapors, they are not affected by poor NPSH conditions. Many LPG pressurized tanks such as railcars and buried tanks have top unloading connections. A compressor can be the perfect solution for transferring liquids to and from such tanks.

Advantages

• Threaded and ANSI flanges
• Oil-free design
• Self-lubricating PTFE¹ step-cut piston rings
• Packing adjustment screw in most models
• Ductile iron construction
• Positively locked piston
• O-ring head gaskets
• High-efficiency valves

Servicability
Corken compressors are designed to minimize required maintenance and make such maintenance extremely simple. Valve replacement may be accomplished without disturbing the piping and ring replacement may be accomplished by simply removing the head.

Versatility
The same compressor installed for one application can easily be piped to be utilized for other plant applications. An example would be a railcar-unloading, in which the compressor can also be utilized to load and unload trucks.

Truck Compressor Applications
Corken's LPG compressors have an extended crankshaft option for utilization on trucks with PTO and hydraulic drive systems. The compressor can be utilized for loading/ unloading as well as vapor recovery on trucks.
