Abstract (en)
[origin: US2017175749A1] A centrifugal pump includes at least one pump stage (14). This pump stage (14) includes an impeller (18) which is mounted rotationally fixed on a pump shaft (26). Apart from the pump stage (14), the centrifugal pump is equipped with a turbine wheel (32) which is arranged on the pump shaft (26), without a movement coupling to the pump shaft, in the delivery flow of the centrifugal pump. This turbine wheel (32) forms a transducer of a flow measuring device. A blading of the turbine wheel (32) is such that a torque exerted by the delivery flow onto the turbine wheel (32′) is directed counter to a torque exerted via the pump shaft (26) onto the impeller (18).
