The cowling (5) of 10 the motor comprises an upper peripheral lip (10) that projects radially away from the external peripheral surface (9) of the cowling (5). The central passage (8) of the lower volute (6) is bordered internally by an annular shoulder (11), an annular seal (14) being arranged on said annular shoulder (11). The 15 lower volute (6) also comprises a number of internal stops (12) that are borne by the internal surface (13) of the lower volute (6). The upper peripheral lip (10) of the cowling (5) of the motor is positioned between the annular seal (14) and the internal stops (12) of the lower volute (6), said internal 20 stops (12) bearing against said upper peripheral lip (10) of the cowling (5) of the motor so as to achieve compression of the annular seal (14) between said upper peripheral lip (10) of the cowling (5) and the annular shoulder (11) of the lower volute (6). 252/8 724 23 7a 30 6a 6 22 FIG. 2a 17 2,5 22FIG. 2b
