A pump for a beverage preparation machine which includes a heat-radiating electric arrangement； and a thermo-fuse connected to the electric arrangement via an electric connection. The thermo-fuse is connectable to a power source for powering the heat-radiating electric arrangement via the thermo-fuse. The thermo-fuse is in thermal communication with the heat-radiating electric arrangement so as to disconnect the electric arrangement from the power source when the thermo-fuse reaches a predetermined maximum temperature in reaction to an excessive heat radiation from the electric arrangement. The thermo-fuse and the heat-radiating electric arrangement are so configured that heat radiating from the electric arrangement to the thermo-fuse is predominantly conducted along the electric connection from the electric arrangement to the thermo-fuse.
