RCA of Centrifugal Pump Vibration
Centrifugal pump vibration in petrochemical plants poses significant risks to equipment reliability, safety, and process efficiency. This vibration often stems from various mechanical issues such as bearing problems (e.g., worn or improperly lubricated bearings) and misalignment in shafts or couplings. Such mechanical failures generate excessive friction and stress, which may lead to costly, catastrophic pump failures.
Operational factors like cavitation—often caused by a blocked inlet or inadequate Net Positive Suction Head (NPSH)—can damage internal pump components. Running pumps beyond recommended speed or overloading also contributes to erratic vibrations. Additionally, environmental influences, such as temperature fluctuations or vibrations from nearby machinery, accelerate wear, with structural resonance from nearby equipment further aggravating the issue.
Poor maintenance practices, including infrequent inspections and insufficient vibration monitoring, can compromise pump reliability. Use of substandard parts or incorrect reassembly during repairs can lead to recurring issues. Lastly, design and installation issues—like low-quality materials, inadequate vibration isolation, and improper foundation setup—undermine long-term pump performance.
To address these challenges effectively, petrochemical plants can leverage ProSolvr, a GEN-AI-powered visual RCA tool. With its structured, Six-Sigma-based fishbone diagram, ProSolvr enables teams to systematically identify and categorize root causes across key areas—mechanical, operational, environmental, and design-related factors. By visualizing each potential cause, teams can pinpoint and resolve root issues, resulting in safer, more reliable pump operations.

Root Cause Analysis (RCA) of Centrifugal Pump Vibration in petrochemical plants provides valuable insights for various stakeholders
- Maintenance Engineers: They can use this CAPA framework to identify specific corrective actions for immediate issues and implement preventive maintenance schedules to minimize equipment wear. This helps them address root causes of mechanical and operational issues before they escalate.
- Reliability Engineers: With this structured approach, reliability engineers can systematically investigate and document failure modes in pumps, enhancing future reliability assessments. It supports their goal of reducing unscheduled downtimes and improving equipment lifespan.
- Operations Supervisors: The CAPA template provides them with clear guidelines on preventing improper pump operation and enforcing best practices. It ensures that start-up and operational procedures are consistently followed to avoid vibration-related issues.
- Quality Control Teams: Quality control can leverage the CAPA process to ensure standards are met in equipment performance and operational procedures. This helps them monitor for recurring issues and establish improvements based on past incidents.
- Process Engineers: Process engineers can apply this framework to assess how process-related factors like cavitation affect pump performance. It assists them in developing process adjustments to optimize pump function and mitigate vibrations.
Why use this template?
A Gen-AI driven, visual root cause analysis with ProSolvr can aid in developing corrective and preventive actions (CAPA) that target each identified issue precisely. By implementing these suggested actions, plants can effectively mitigate and manage centrifugal pump vibration issues, enhancing equipment longevity and overall operational reliability. This Six Sigma-guided, visual approach not only resolves existing issues but also lays out a roadmap to improve reliability and prevent recurrence, ultimately enhancing safety and efficiency across petrochemical plant operations.
