Abstract (en)

The method involves determining significant number of revolutions of a centrifugal pump for different marked operating points with completely installed lifting device, with an electric motor driving the centrifugal pump and equipped with a programmable frequency converter (10). The revolutions are stored together with the data in a control unit controlling the device. The revolutions are added for further operation. An independent claim is also included for a sewage lifting device for executing a method for adjustment and operation of a sewage lifting device.
