Common Failure Modes of Electro-pumps in Industries

This paper investigates the common faults of electro-pumps using vibration. The pumps studied in this research include various types of electro-pumps in some industries such as water and waste water, petrochemical complexes, and power plants. Using vibration analysis of, the major faults of these pumps are extracted and the effect of the support type is examined. As a result, three faults of imbalance, bearings faults, and misalignment are recognized as the important causes of electropumps failures.
