A tank (1) having saturated water (2) is connected to a pump (5) via a suction line (4). The actual values of the pressure and/or temperature in the tank (1) are detected to a measuring arrangement (7) and supplied to a control apparatus (8), in which the actual values are compared with fixed values. In a water reservoir (9) there is admixing water, the temperature of which is lower than the actual temperature in the tank (1). This water reservoir (9) is connected to the suction line (4) via an inflow line (11). An actuator (12) which is activated by the control apparatus (8) is arranged in the inflow line (11). When the actual values in the tank (1) reach the fixed values, so that the pump (5) could experience cavitation, the actuator (12) is opened by means of the control apparatus (8), in order to introduce admixing water into the suction line (4).
