Abstract (en)
[origin: EP1134415A2] The membrane pump comprises a hydraulically driven membrane (10) whose clamping zone between the housing (36) and the lid (34) is additionally provided with at least one elastic element (40) which is constituted so that it compensates the diminishing clamping force on the membrane.
