摘要： A video sequence of a pump assembly or of a pump assembly part is produced. The video sequence is evaluated by way of digital signal processing assisted by a data base. A condition of the pump assembly is determined by way of this evaluation. In particular it is determined whether the pump runs in a designated manner or it is determined whether unallowably high oscillations are ascertained in a region, wherein this would indicate a defect, for example bearing damage or an unfavorable speed
