Abstract
A method is provided for monitoring the operating status of one or more pumps, particularly gear pumps, whereby system parameters are determined by a corresponding measuring device. The system parameters are subsequently processed in a local evaluation unit into characteristic numbers. Finally at least some of the characteristic numbers determined in the local evaluation unit are transmitted from the pump and/or the local evaluation unit to the central evaluation unit. Based on the characteristic numbers, the operating status of the pump is determined and if necessary, an appropriate action is triggered.
