Abstract:
Diaphragm pump comprising:a hydraulic power source, a single layer diaphragm hydraulically powered by said hydraulic power source and chucked at 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 so that the press-on force will be below the flow limit of the diaphragm material, and in the chucking area, only one elastic part in a shape of only one axially acting profile ring located between said diaphragm and said pump lid for achieving a desired elasticity adjustment that elastically compensates for any reductions occurring during the operation of the diaphragm pump in the press-on force in the chucking area of the diaphragm between the pump lid and the pump housing, the elastic part being a lip seal.
