After being refurbished, the motors experienced excessive vibration at certain pump speeds, thereby restricting the pumping system’s ability to handle various flow ranges. A permanent fix was sought out since pump rental costs significantly increased the cost of operating the pump station.

Focusing on vibration and dynamics issues during the plant design phase of a project pays off with smoother commissioning and lower cost of ownership over the plant’s life.
Troubleshoot and identify potential opportunities for early bearing failure, MSI performed experimental modal analysis (EMA) and operational deflection shape (ODS) tests on a prototype unit for the manufacturer.
