Abstract

Die Erfindung bezweckt die Schaffung einer Befestigungs­ einrichtung für aus sprödem Material bestehende Kreisel­ pumpenlaufräder, die zwei Bedingungen erfüllt:
Erstens dürfen durch die Befestigungseinrichtung wegen der bestehenden Bruchgefahr keine Zugkräfte in das Kreisel­ pumpenlaufrad eingeleitet werden;
zweitens darf die durch das Laufrad und durch die Kreiselpumpe fließende Strömung durch die Befestigungseinrichtung nicht gestört werden.
Demgemäß ist das Kreiselpumpenlaufrad (1) auf seiner Druckseite in einer Scheibe (2) aus duktilem Material gefaßt, wobei die Verbindung zwischen dem Kreiselpumpenlaufrad (1) und der Scheibe (2) im Bereich des Außendurchmessers erfolgt.
