In a pump control device (1,1') comprising a casing (2,3;2',3') and a speed controller (20), in particular a frequency converter, arranged in the casing for controlling the rotational speed of an electric drive motor (103; 103') of a fluid pump (100; 100'), the casi ng includes a section (3; 3') of good thermal conductivity in which a cavity (4; 4') is formed which exhibits connections (5, 6, 7; 5', 6') for coupling with the output (102; 102') of a fluid pump (100; 100') to be controlled by the pump control device and with pipes so th at the cavity (4; 4') can be passed through by the entire fluid stream delivered by the fluid pump, wherein the speed controller (20) is connected in a heat-conducting manner to the casing portion (3; 3') of good thermal conductivity. |
