Abstract (en)
[origin: WO2006129192A1] An impeller for centrifugal pumps with permanent-magnet synchronous motor, comprising a main blade array (4a-4c) and an additional blade array (6a-6c) of moving blades; in the nominal direction of rotation the moving blades are resting on the main blades, so that they work as a single blading; in the event of reverse rotation the moving blades are separated from the main blades, so that they can act separately on the fluid flow.
