Troubleshooting Rotodynamic Pump Vibration Issues

1-Part Live Webinar

August 23, 2022 at 1 pm (EDT)


This webinar presents a high-level step-by-step description of troubleshooting techniques to successfully address vibration issues on rotodynamic pumps.  The main focus is on centrifugal pumps of all types regarding their typical vibration issues such as imbalance, misalignment, rub, looseness, structural resonance, rotodynamic resonance, thermal loading issues, piping strain, flow-induced sub-synchronous vibration, internal recirculation, rotating stall, shaft failure, etc.

Learning Objectives

During this webinar, participants will learn:

  • How to attack a pump vibration problem
  • Identify the instrumentation and the test methods required to uncover the root cause of the vibration issue
  • How to analyze the data using time wave form, frequency spectral analysis (FFT), continuous monitoring, modal analysis (bump testing), motion magnification video (MMV), and operating deflection shape (ODS)
  • Symptoms such as imbalance, misalignment, structural resonances, acoustic issues, torsional natural frequencies, cavitation, rotating stall, rubbing, and looseness are discussed
  • Solution methods using finite element analysis (FEA) are discussed along with a detailed case study
