Because when the vibration exceeds the ISO standard threshold can affect the age of use of centrifugal pumps and data in the form of value. vibration documentation can be as a reference for maintenance or when troubleshooting will occur. The research was conducted to determine the high and low vibration generated during placement of the belt / flange installation. By varying the design of the belt mounting position and knowing the displacement, velocity, acceleration, at the vibration. By using a vibration meter measuring instrument with the position of a horizontal measurement point, the vibration device will point to the value of a digital number. This study found that measurement of deep belt displacement with an external design belt received a low vibration value (0.01mm) compared to the outer and outer belt design. For the measurement of the lowest vibration velocity values 0.12-0.13 m / sec. While the lowest acceleration vibration measurement is in the belt design position in the outer 3.1 m / sec2 with 18 sec.} }
