Abstract: The invention relates to a diaphragm pump (1) which has in at least one pump head (2) a working or pump diaphragm (3) which, by means of a clamping zone (4) arranged at its outer circumference, is clamped between two housing parts (5, 6) of a pump housing and which, between itself and a pump head part (6), borders a working or delivery chamber (8) and which, in a central zone (10), surrounds a diaphragm armature (11) which, on its side facing away from the working or delivery chamber (8) of the at least one pump head (2), is connected to a stroke drive (12) which is provided for generating an oscillating stroke movement of the working or pump diaphragm (3). The diaphragm pump according to the invention is characterized in that the annular zone arranged adjacent to the clamping zone (4) is formed as a guide zone (14) which, in the unloaded state of the working or pump diaphragm, is convexly curved and projects into the working or delivery chamber (8), with which guide zone (14) the working or pump diaphragm (3) rolls on a complementarily shaped annular or support zone (15) of the pump head (2) during the stroke movement of the working or pump diaphragm (3), and that a compensating zone (16) of the working or pump diaphragm (3) is provided between the guide zone (14) and the central zone (10), which compensating zone, in the unloaded state, is in contrast curved concavely and in the direction of the stroke drive (12). The diaphragm pump according to the invention is characterized by improved pump performance, a long service life and quiet and low-vibration pump operation.

Abstract: The invention relates to a multi-stage diaphragm suction pump, comprising at least two pump chambers, each having a fluid inlet having at least one inlet valve, and a fluid outlet having at least one outlet valve, and a suction line, which connects the fluid inlets of the pump chambers. Consecutive pump chambers are connected to each other by means of at least one connection line such that, when a differential pressure in the suction line is reached/exceeded, the diaphragm pump changes from parallel operation of the pump chambers thereof to an operating mode of said pump chambers that is at least also serial. At least one check valve, which opens to the downstream pump stage, is interposed in each of the inflow and outflow regions of the at least one connection line. In order to optimize the pump characteristic of such a diaphragm suction pump, according to the invention at least in one pump chamber, either in order to improve the intake pressure the suction-side opening of the at least one connection line, or in order to improve the suction capacity the pressure-side opening of the at least one connection line, is disposed in the region of the pump chamber, or in the vicinity of the region of the pump chamber, on which the diaphragm associated with said pump chamber rolls off first during a pump cycle. In addition, or instead, according to a further embodiment at least one connection line, in particular between successive pump chambers, has a descending line progression and, for this purpose, compared to the outflow-side line segment, the inflow-side line segment of said at least one connection line is arranged at a higher level.
