Abstract: Equipment availability depends at the same time on these 3 fundamental parameters: Reliability or the number of failures; reparation celerity of failures. Maintenance and Rules defined for maintenance and repair: Maintenance logistics. It will be noticed that there are interactions between these various aspects. A maintenance policy cannot be defined without the characteristics of the system to maintain and the capacity of the logistical support. Responsibility frontier between the manufacturer and the user is versatile and variable in each case. Maintenance costs are often considerable and can be appreciably reduced by a predictive maintenance. The aim of this study, is to present on an industrial case, the advantages of the predictive maintenance carried out to a monitoring and a vibratory diagnosis on turbo-pumps. Various techniques of analysis are applied, the results show that predictive maintenance in this application allowed to reduce the costs of maintenance, the number of breakdown, the downtime and to increase the lifespan of the machines and their availability. Technical resources used as sensors, instrumentation, diagnosis data base constitution and the follow-up of the machines are presented.
