Reciprocating Compressors (Vertical)

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 LPG tanks such as tank cars, railcars 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. Our Corken 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.

Plain Style Reciprocating Compressor

Corken's plain style reciprocating compressors utilize one set of V-ring packing per piston rod and do not have a distance piece. Plain style configurations are not oil-free designs. Typically used in non-toxic, non-corrosive applications where oil-free gas is not required and leakage containment is not critical. If oil-free gas compression is required, a D-Style or T-Style vertical compressor is recommended.
 
Piston displacements up to 117 cfm (198.8 m3/hr)
Working pressures up to 450 psi (31.0 bar g)
Brake horsepower up to 45 hp (34 kW)
Maximum outlet temperature: 350 °F (177 °C)

D-Style Oil-Free Reciprocating Compressors

Corken's 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.
 
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)

T-Style Oil-Free Reciprocating Compressors

Corken's T-Style vertical compressors utilize three sets of V-ring packing per piston rod and two (double) distance pieces. The lower packing set has an adjustable packing screw that is used to maintain the sealing performance over the life of the packing. All T-Style vertical compressors deliver oil-free gas compression. Typically used in toxic and corrosive applications where oil-free gas and maximum leakage containment are critical.
 
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)
