the present invention relates to a method for controlling the rotation speed of a centrifugal pump operated in an open hydraulic circuit, in which the controller of the pump control system determines the desired rotation speed of the pump drive, taking into account a desired delivery head and an actual delivery head, as well as the actual rotational speed. more specifically, the present invention relates to a centrifugal pump and a method for controlling the speed of rotation of a centrifugal pump operated in an open hydraulic circuit, in which the pump control system controller determines a desired speed of rotation of the pump drive, taking into account a desired delivery head and an actual delivery head, as well as the actual rotation speed, in which, for the calculation of the desired rotation speed, the controller takes into account a correction parameter for describe the geodesic head.
