Abstract (en)
[origin: EP2738386A1] The pump element (1) has a cover plate (15) and a base plate (12) which is arranged in a predefined distance to the cover plate, where a coupling bar (6) is arranged between the cover plate and the base plate. The coupling bar is coupled with an actuator unit and is movable between the base plate and the cover plate. A pump membrane film (10) is arranged between the cover plate and the base plate, where the pump membrane film is connected in a central portion with the coupling bar. Independent claims are included for the following: (1) a dosing pump with a piezoelectric bending transducer; and (2) a method for manufacturing a pump element.
