Abstract
The present invention relates to a method for controlling a pump, in particular a centrifugal pump, during pumping of a liquid, comprising the following steps: fixing a setpoint value of a flow rate of the pump; measuring an inlet pressure of the liquid upstream of the pump and an outlet pressure of the liquid downstream of the pump; determining a setpoint value of a rotational speed of the pump from a performance map of the pump, wherein the fixed setpoint value of the flow rate and a difference between the outlet pressure and the inlet pressure are incorporated into the performance map as input values; and setting the rotational speed of the pump to the setpoint value of the rotational speed. Furthermore, the invention relates to a corresponding device for controlling a pump.
