A film transducer for a pump is described, comprising at least one holding part arranged fixed, a displaceable switch unit and at least two electroactive composite film units which each have at least two electrodes. The electroactive composite film units are each assigned to the holding part and the switch unit. The electroactive composite film units have an actuation direction in which the electroactive composite film units lengthen when actuated, wherein the actuation direction lies in a plane spanned by the electroactive composite film units. Furthermore, a pump and a method for operating a pump are described.
