A high percentage of the pumps brought to us for repair are experiencing a vibration problem There are six main causes of pump vibration problems and any one could take a pump out of service for unplanned and expensive repairs Read on for tips to help you determine whether your pump’s poor performance is due to one of these vibration problems

Some use the rule that when the axial vibration reaches at least 50 percent of the radial vibration horizontal or vertical the source for the vibration is coupling misalignment This rule is a reasonably good one but unfortunately is not always reliable Coupling misalignment doesnt always create high axial vibration
