Abstract

A positive-displacement pump device has at least one shape-memory unit including at least one magnetic shape-memory element, which is configured to convey at least one medium along at least one transport direction, wherein the positive-displacement pump device includes at least one deformation unit, which is configured, for the purpose of providing a transport volume, to deform the magnetic shape-memory element, at least in an idle state in which the positive-displacement pump device is free of a current and/or voltage supply, by a pressure force and/or traction force acting in the transport direction such that the magnetic shape-memory element includes at least one first partial region and at least one second partial region which differ from one another at least by their magnetic orientations.
