A device for leakage detection in pumps or other assemblies for handling electrically conductive, pumpable products, e.g. previously sterilized liquid foods, has a diaphragm which includes, on the one hand, a liquid-tight layer (15) which is located in contact with the product, and, on the other hand, an electrically conductive material layer (16) discrete from the product. The conductive layer (16) is, via a conductor (19) with an indicator (20), electrically connected to the product, and when cracks occur in the diaphragm so that the product comes into contact with the electrically conductive layer, a closed current circuit will be made, which immediately indicates the leakage and makes it possible to avoid the leakage resulting in a contaminated and destroyed product. |
