Finding And Eliminating Chronic Pump Failures
A Gulf Coast refinery decided to actively address rising pump maintenance costs and risk of production losses by using accumulated failure data and maintenance costs to identify bad actor pumps, then solving the problems causing repeat failures. The plant’s computerized maintenance management system (CMMS) was used for the input of condition report data. Standard spreadsheet software was used to analyze data and expose the bad actors. The process of finding the root causes of the chronic problems began with classifying past failures by the agent of mechanical failure: time, temperature, force, and reactive environment. Two case histories are presented that were investigated using this process. The effect on the plant is also presented, including the reduction of bad actor failures by 67 percent.
