Technique for deterring and monitoring internal defect condition of a mud pump during the operation and/or in a laboratory conditions are illustrated. One or more acoustic transducers are attached in the proximity of one or more valves of the pump. Variation(s) in the output signal parameters are continuously monitored. Variation of the signal over the predetermined threshold level indicate a gradual degradation of the pump or if the variation of the signal occurs over a short interval it may indicate a sudden failure of the pump. Likewise, a system of detecting internal defect condition of the pump and apparatus for monitoring the pump condition is illustrated. The techniques are also applied to duplex and/or triplex high-pressure pumps used to push hydrocarbons through pipelines. Apparatus and system similar to that disclosed for the mud pump is equally applicable to the high-pressure pumps used to push hydrocarbons through pipelines.
