1. A transport device for transporting a fluid, the transport device comprising:
(a) a housing, wherein the housing has a fluid inlet and a fluid outlet;
(b) an actuator comprising a magnetic shape-memory alloy, wherein the actuator is at least partially arranged in the housing;
(c) a drive by which the actuator may be deformed in such a way that at least one cavity for the fluid is formed in the actuator, wherein the at least one cavity may be moved by the drive in order to transport the fluid in the at least one cavity from the fluid inlet to the fluid outlet;
(d) wherein at least one section of the actuator has a separation layer by which a direct contact between the fluid and the actuator is prevented in said section of the actuator;
(e) wherein the transport device further comprises a sealing element, wherein at least one section of the sealing element has an elastic property so that a section of the sealing element sealingly abuts against a section of the at least one cavity of the actuator when the at least one cavity is formed in the actuator by the drive.
