Vertical Pump and Motor vibration
Vertical Pump and Motor vibration
(OP)
After we set a vertical pump and motor, upon startup, the pump had vibrations exceeding the recommended alarm limits. When the pump base bolts are loosened, the vibration falls within the acceptable alarm limits. What could be causing the high vibration when the pump base bolts are tightened down?

Are you sure it is the pump that vibrated, and not the structure it is attached to?
