Abstract (en)
[origin: EP2735744A2] The impeller has a rear-side support plate (7) on which several runner blades (8) are arranged by which rear side of the permanent magnets (12) are secured. Permanent magnets are arranged within the extrusion-coated plastic side of the rear-side support plate for trapping the feed liquid particles present in the impeller main portion. A material layer is arranged on the side of the magnets which are faced on the rear-side support plate for covering the magnet and rear-side support plate, such that the coverage of injection-molded portion is formed.
