Abstract: A device for determining a leakage of fluid in a piston pump, wherein the piston pump comprises a piston arranged in such a manner that it can reciprocate in a piston chamber for delivering fluid, wherein the device comprises a control unit for controlling the piston in such a manner that the piston executes two piston chamber evacuation processes with different evacuation times, in each case for at least partial evacuating of fluid located in the piston chamber, and a determination unit for determining the leakage based on a comparison of fluid quantities evacuated from the piston chamber in the two piston chamber evacuation processes.
