Abstract

A monodirectional impeller for centrifugal electric pumps having a permanent-magnet synchronous motor, comprising vanes (13) that are deformable at least along part of their extension so as to change their curvature, when loaded, in one direction of rotation, said vanes (13) being nondeformable adjacent to the rotation axis and being elastically deformable in their peripheral region, so that the power required for rotation in that direction is greater than the maximum power that can be delivered by the motor. <IMAGE>
