Pump Vibration Monitoring Basics | Pumps & Systems

Many pump vibrations are directly related to the running speed of the pump (or multiples of the running speed) and the motor drive system. These vibrations occur in the mid- to high-frequency range of 450 to 60,000 cpm (7.5 to 1,000 Hz). These examples include harmonics of drive motor and pump running speed and vane/impeller pass frequency.
