—Vibration analysis is fundamental in enhancing condition monitoring and fault diagnostics of control unit in swash plate pumps. Several signal analysis methods are used to obtain useful information from vibration signatures. Presently, the most of these methods use spectral analysis based on Fourier Transform (FT). However, these methods exhibit some limitations; it is the case of transient signals when the irregularity is the pattern. In the present paper, we are interested to apply Discrete Wavelet Analysis (DWA) to the vibration signal analysis. The DWT is one of the most promising methods for signal processing; it is especially convenient for transient vibration measurements obtained from accelerometer sensors. The monitoring results indicate that the DWT can diagnose the abnormal change in the measured data.
