Abstract
Pump vanes are deformable at least along part of their extension and can change their curvature when loaded in one direction of rotation so that the power required for rotation in that direction is greater than the maximum power of the motor. The impeller comprises a plastic ring with a number of rings protruding outward. The ring is accommodated in a corresponding seat of a disk which ends at the vane perimeter. A driving device is formed by a cylindrical enclosure rigidly coupled to the impeller interacting with a tooth protruding from the ring. The ring is rotatable about a shank rigidly coupled to the rotor shaft.
