Abstract
A centrifugal pump includes at least one pump stage (). This pump stage () includes an impeller () which is mounted rotationally fixed on a pump shaft (). Apart from the pump stage (), the centrifugal pump is equipped with a turbine wheel () which is arranged on the pump shaft (), without a movement coupling to the pump shaft, in the delivery flow of the centrifugal pump. This turbine wheel () forms a transducer of a flow measuring device. A blading of the turbine wheel () is such that a torque exerted by the delivery flow onto the turbine wheel (') is directed counter to a torque exerted via the pump shaft () onto the impeller ().
