Abstract

Kreiselpumpe, insbesondere Baggerpumpe zum Fördern eines Feststoff-Wasser-Gemisches, mit

  • einem Pumpengehäuse mit einem axialen Saugeinlass und einer Lageröffnung auf der gegenüberliegenden Seite
  • einer Antriebswelle, die über die Lageröffnung in das Pumpengehäuse hineinsteht
  • einem innerhalb des Pumpengehäuses angeordneten Pumpenkreisel, der sich aus zwei beabstandeten Scheiben und zwischen den Scheiben angeordneten mit den Scheiben verbundenen Schaufeln zusammensetzt und der mittels eines an der lagerseitigen Scheibe angebrachten Nabenabschnitts drehfest auf dem Wellenende angeordnet ist und
  • einem Umlenkabschnitt aus geeignetem Kunststoffmaterial oder Gummi zwischen Nabenabschnitt und Innenseite der lagerseitigen Scheibe.
Figure 00000001
Centrifugal pump, in particular an excavator pump for conveying a solid-water mixture
  • a pump housing with an axial suction inlet and a bearing opening on the opposite side
  • a drive shaft that protrudes into the pump housing via the bearing opening
  • a pump gyro arranged within the pump housing, which is composed of two spaced disks and blades arranged between the disks and connected to the disks and which is arranged in a rotationally fixed manner on the shaft end by means of a hub section attached to the bearing-side disk and
  • a deflection section made of suitable plastic material or rubber between the hub section and the inside of the bearing-side disk.
