Corken D-Style Oil-Free Reciprocating Compressors

Corken's reciprocating compressors are an ideal solution for liquid transfer applications in systems with poor net positive suction head (NPSH) conditions. Unlike liquid pumps, which can suffer from excessive maintenance due to inadequate NPSH, reciprocating compressors handle only vapor, making them unaffected by such conditions. This ensures reliable performance in challenging environments, reducing maintenance requirements.
