In this paper the power consumption model of a circulating wet runner pump is presented. Such a model provides several advantages since it can be used for example to detect issues during operation of the pump. For instance, dry running which might damage the bearings of the pump can be detected based on deviations between the measured power and the power predicted by the model. Furthermore, based on the power model the volume ﬂow which passes the pump can be determined without a volume ﬂow sensor and thus save costs. As the overall power consumption of the pump is inﬂuenced by different components such as electrical and friction losses, models of the individual components which have an inﬂuence on the power consumption are presented. Then, the components are combined to one overall power consumption model and the model parameters are identiﬁed by measurements. Finally, the model is validated by comparison of the dynamic behaviour of the model with the actual measured power consumption.
