Abstract (en)
[origin: US4462752A] Shaftless centrifugal pumps have particularly advantageous running characteristics when installed vertically. But in order to make it possible for the delivery stream also to run vertically, the pipe connectors form bends, the ends of which can be integrated into a vertical pipeline.
Abstract (de)
Wellenlose Kreiselpumpen weisen besonders günstige Laufeigenschaften bei vertikalem Einbau auf. Damit aber auch der Förderstrom vertikal verlaufen kann, bilden die Anschlußstutzen (2, 3) Krümmer, deren Enden (6, 6') in eine vertikale Rohrleitung eingebunden werden können.
