Plain-Style Reciprocating Compressor Overview
Corken’s plain style horizontal reciprocating compressors only have one set of segmented packing per piston rod and no distance piece. The plain style reciprocating compressor is not oil free and has a basic packing arrangement with either a standard or purge packing configuration that delivers a minimum level of leakage containment. Unlike Corken’s vertical reciprocating compressors that use a V-ring packing design, the horizontal compressors use segmented packing to seal the piston rod. The standard packing configuration uses segmented packing only while the purge packing configuration uses a combination of purge and segmented packing.
If oil-free gas compression and maximum leakage containment are required, Corken’s T-Style horizontal compressors are recommended. Plain style compressors are typically used in non-toxic and non-corrosive applications where oil-free gas and leakage containment are not critical. LPG (propane & butane), agricultural ammonia, and natural gas applications are a few examples.
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.
