Abstract

Dichtungsfreie Pumpe, bei der in einem Gehäuse eine An­ triebsspindel (8), die in Antriebsverbindung (7) mit einem Elektro­ motor (4,5) steht, und wenigstens eine, vorzugsweise zwei, mit ihr kämmende Laufspindel(n) (12) gelagert sind, vorzugsweise zum Fördern von niedrig viskosen Flüssigkeiten, wobei der Rotor des Elektromotors (15) das außenzylindrische Pumpengehäuse (6) um­ gibt und an einem Ende durch Verbindung (7) mit der Antriebs­ spindel (8) gelagert ist. Seal-free pump, in which an on in a housing drive spindle (8) in drive connection (7) with an electric motor (4,5), and at least one, preferably two, with her intermeshing spindle (s) (12) are mounted, preferably for Conveying low-viscosity liquids, the rotor of the electric motor (15) around the outer cylindrical pump housing (6) there and at one end by connection (7) to the drive spindle (8) is mounted.
