The invention proposes a process and an apparatus by which the expenditure previously necessary for filling ready-fitted electric motors with a casting composition is considerably reduced.
<??>The process according to the invention, advantageous for example for filling with a casting composition the canned motor of a heating circulation pump intended for cold water operation, is characterised in that one or more holes, serving as pouring-in openings, are drilled into the wall of the motor housing, the chips produced during drilling being taken away by a suction-removal device, and in that the electric motor is filled with liquid casting resin, preferably under pressure, via the pouring-in opening or openings.
