Abstract

In a fist aspect the invention relates to a method for controlling a drainage pump (2), the drainage pump (2) comprising a drive unit having an electrical motor (7) and a drive shaft (8) and comprising a hydraulic unit having an impeller (9) operatively connected to said electrical motor (7) via said drive shaft (8), said drainage pump (2) being configured to be operated at a variable operational speed [rpm]. The method is characterized by the steps of continuously operating the drainage pump (2) at a positive operational speed, intermittently detecting whether the drainage pump (2) is snoring or not, decreasing the operational speed (OP) of the drainage pump (2) one step every time snoring is detected, and increasing the operational speed (OP) of the drainage pump (2) one step every time snoring is not detected. In a second aspect the invention also relates to a drainage pump assembly.
