These videos show the highest vibration is at 1X rotational speed (20 Hz) in the East/West direction viewed on both the pump and motor due to resonance. Looseness was observed at the pump base bolts (approximately 0.3 mils pk-pk), at the motor to pump top plate (approx. 3 mils pk-pk) and at the bolted joint connecting the lower motor housing to the stator section (approx. 3-4 mils pk-pk). All displacement values are calculated using software algorithms.
