  • PUMP VIBRATION EXPLAINED

    Bent shaft problems cause high axial vibration with axial phase differences tending towards 180° on the same rotor. Dominant vibration normally occurs at 1X RPM if bent near shaft center, but at 2X RPM if bent near the coupling. Pump bent shafts are more common at or near the coupling. Dial indicators can be used to confirm a bent shaft.
