Abstract
A diaphragm pump with hydraulically powered diaphragm that is so chucked on a circulating rim between a pump lid and a pump housing in a predetermined radial chucking area and with a predetermined press-on force between the pump lid and the pump housing that the press-on force will be below a flow limit of the diaphragm material. At least one elastic part is provided additionally in the chucking area. That part is so designed that it will elastically compensate for any reductions occurring during the operation of the diaphragm pump in the press-on pressure in the chucking area of the diaphragm between the pump lid and the pump housing.
