Knowledge of vibration and the resulting data is very important for maintenance and troubleshooting where this ability can help companies reduce the occurrence of downtime and can increase profits both in terms of production and from a longer machine life. One of the causes of high vibrations is a misalignment in a centrifugal pump installation that is driven by an electric motor and connected by a fixed clutch. The method used is to do differences in height in the horizontal, vertical and angular directions by providing variations in the rotation of the electric motor and pump, then checking at four bearing positions on the electric motor and pump. The results showed an increase in vibration at each addition of the sim on the electric motor fastener bolts, the greatest vibration occurred in the MOV (indoor motor axiall) with the addition of a 1.5mm sim of 3.01 mm / sec an average increase of 29% and at the largest pump vibration in POA (outdoor axial pump) with the addition of a 1.5mm sim of 9.88mm / sec, increased by an average of 58%.
