Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Cavitation
Cause: Localized pressure drops below vapor pressure, forming and collapsing vapor bubbles that cause surface pitting and material fatigue, often due to improper fluid velocity, temperature, or suction conditions.
Abrasive erosion
Cause: High-velocity particulate matter in the fluid stream impacting internal surfaces, leading to gradual material loss and dimensional changes, typically from inadequate filtration or contaminated process media.
Maintenance Indicators
  • Unusual high-frequency vibration or audible knocking sounds indicating cavitation or impeller imbalance
  • Progressive drop in output pressure or flow rate despite constant input, signaling internal wear or blockage
Engineering Tips
  • Implement real-time pressure and temperature monitoring with automated controls to maintain operating parameters within optimal ranges, preventing cavitation conditions
  • Install multi-stage filtration systems with regular maintenance schedules to remove particulates, and apply wear-resistant coatings or materials on high-velocity contact surfaces
