Abstract

Eine energiesparende, geräuscharme und leistungsstarke Pumpe (3), insbesondere Umwälzpumpe für Haushaltsmaschinen wie Wasch- oder Spülmaschinen und Maschinen ähnlicher Bauart mit einem in einem Pumpengehäuse (11) drehbar gelagerten und mit Schaufeln (7) bestückten Pumpenrad (9 wird dadurch erhalten, daß die Innenumfänge des Pumpengehäuses (11) und / oder der Verbindungsschläuche und / oder die Oberfläche des Pumpenrades (9) wasserabweisende, strömungsverbessernde bzw. reibungsvermindernde Oberflächenstrukturen bzw. -schichten aufweisen.

Figure 00000001
An energy-saving, low-noise and powerful pump (3), in particular circulation pump for household machines such as washing machines or dishwashers and machines of a similar design with a pump wheel (9) rotatably mounted in a pump housing (11) and equipped with blades (7) is obtained in that the Internal surfaces of the pump housing (11) and / or the connecting hoses and / or the surface of the pump wheel (9) have water-repellent, flow-improving or friction-reducing surface structures or layers.
