Abstract :
Pump is instrument condelivery fluids from media place to other place
using piping system by added some energies to the fluids continuously.
Centrifugal pump kind that uses in industries that worked by impeller rotation as
fluid tranfered that driven by mover. Decreased performance of suddenly and
unstable in operating, because performance of pump discreased totally.
This research will analyze the speed vibration of Sentrifugal pump in PT.
Pertamina RU II Sei Pakning by knowing the value of threshold of vibration in
according with ISO 10816-vibration severity standard. The tree pumps are pump
PM 2B, pump 2C and pump 2D while the dominan highest vibration value of
pump PM 2B.
