By Allan R Budris Excessive vibration is a good indicator that some damaging phenomenon could be occurring within a pump or the immediate pump system which is why many pump users monitor pump vibration on a regular basispump impeller obstruction by foreign objects causing the axial vibration typically at running speed to increase If the pump has an overhung impeller this will usually cause high 1X RPM in both the axial
