Lubrication

 

The oil and lubrication system plays a very significant role in the performance of a reciprocating compressor. Too much, too little or inconsistent delivery can reduce performance, lead to premature wear and potentially result in catastrophic failure.

CPI provides industry leading lubrication systems, products and services, partnering with our customers to develop individual solutions to their unique lubrication needs.

From individual components to complete, turnkey systems like our SAFEGUARD™ 1000 or SAFEGUARD™ 5000 lube consoles, we can provide the resources and expertise to ensure your compressor operates at peak performance and longevity.
