Abstract
In order to provide a diaphragm rupture signalling device for a diaphragm pump, which ensures a more functionally reliable rupture signalling compared to the prior art, a diaphragm to be arranged between the drive unit and the delivery unit is disclosed, with at least a first and a second essentially circular diaphragm layer, wherein the diaphragm has a clamping area and an operating area and a sensor area arranged in the section of the clamping area in which at least one of the diaphragm layers is designed such that, when the pressure between this diaphragm layer and the adjacent diaphragm layer increases, it moves further away from the adjacent diaphragm layer in the section of the sensor area than in the other sections of the diaphragm, with an increase in the distance between the diaphragm layers, thereby triggering a diaphragm rupture signalling signal in the diaphragm pump.
