1. A motor-pump assembly conceived to make a liquid circulate and comprising a pump driven by a shaft which is itself driven by an electric motor, the rotor casing of this motor communicating with the pump, the rotor of this motor being thus immerged in the liquid, and comprising a solid support (12, 12') for limiting the liquid exchanges between the pump case (1) and the rotor (3) case (5), in the zone between these two cases, this solid support being carried by the shaft (4) and carrying a surface (16) which is centered on the axis (9) of the shaft (4) and is located transversally to the latter, characterized in that this surface is applied against a corresponding stationary surface (17) only by means of the axial pressure resulting from the operation of the pump (1). |
