Abstract (en)

[origin: EP1134414A2] The membrane pump with a hydraulically driven membrane (10) comprises an insert (34) bounding the delivery space (12) and/or an insert (32) bounding the hydraulic drive space (14). The membrane is clamped between the insert (34) and the pump housing (28) or between the insert (32) and the pump lid (26). Alternatively, in the case where both inserts are present, the membrane is clamped between the inserts.
