Abstract (en)
[origin: EP1843043A2] The pump (1) has a drive device (11) comprising electronic circuits (16) for controlling a drive motor (9), which are arranged in an internal space (8), where low pressure prevails in the internal space. A separating unit has a printed circuit board (10), which separates the internal space from the surrounding. The printed circuit board includes a generating unit (12) for generating electric current and voltages in the internal space, where the generating unit includes a hermetically sealed connector or a stud soldered in a borehole of the board.
