Abstract

Bei derartigen Pumpen besteht das Problem, daß ein Laufgeräusch vorliegt.The problem with such pumps is that there is running noise.

Hiergegen weist die neue Pumpe die Merkmale auf, daß die Pumpenlaufradnaben (9, 10) in ihrer Wellenaufnahmeöffnung (12) Klebefugen (13) aufweist, die zwischen den Preßflächen der Laufradnabe (9, 10) und der Motorwelle (11) bestehen und mit Kleber (14) gefüllt sind.In contrast, the new pump has the features that the pump impeller hubs (9, 10) in its shaft receiving opening (12) has adhesive joints (13) between the Press surfaces of the impeller hub (9, 10) and the motor shaft (11) exist and with adhesive (14) are filled.

Die neue Pumpe ermöglicht einen geräuscharmen Betrieb und ist kostengünstig herstellbar.
