Abstract

Die Erfindung betrifft eine Kreiselmotorpumpe in Nassläuferbauart mit einem den Elektromotorenrotor umgebenden Spalttopf oder Spaltrohr, wobei der Spalttopf oder das Spaltrohr so weit zum Pumpenlaufrad geführt ist, dass er/es das Pumpenlaufrad umgibt und die Wand des insbesondere spiralförmigen Pumpenraums vollständig oder teilweise bildet, und dass der dem Pumpeneinlass zugewandte Bereich der Pumpenraumwand an dem Rand der Pumpeneinlassöffnung und/oder der Pumpenauslassöffnung angeschlossen und flexibel ist, um als Entkopplungselement Bewegungen des Spalttopfes oder Spaltrohres gegenüber dem Pumpengehäuse begrenzt zuzulassen.
