		abstract={A pump is a mechanical part of a machine equipment that is used to increase fluids fluda from one place to another and also from the lowlands to the highland as well as a flow rate amplifier on a centrifugal pump piping, a pump that uses the impeller coupled as the main driver. Halberg-Ludw ligshafen Centrifugal Pump at the faculty Energy Technology and Business, PLN Institute of Technology have not operated for a long time causal factors old age and the possibility and damage to the components therein, therefore it will carry out maintenance and also check the pump with this Examination on centrifugal pump components leads to the impeller and shaft due to (two) parts plays an important role in the pump, this time the inspection by means of the NDT method (Non Destructive Test) is the examination there or not dafective in a workpiece with testing without damage.}
