Abstract (en)

A, preferably computer-implemented, method for controlling and/or monitoring an operation of a pump system (1), wherein the pump system (1) comprises a pump (2) and a motor (3) that is connected to drive the pump (2), the method comprising the steps of: determining a plurality of cavitation indicators (10), wherein each cavitation indicator (11, 12) indicates cavitation or a likelihood of cavitation of the pump (2) for different operating ranges (21, 22, 31, 32), wherein each operating range (21, 22, 31, 32) is given by a combination of values of a first and a second motor characteristic.
