Abstract

Exzenterschneckenpumpe, umfassend einen Pumpenkörper mit einem relativ zum Pumpenkörper drehbaren schneckenartigen Rotor, der über ein Verbindungsmittel mit einem Antriebsmotor, über den der Rotor drehbar ist, koppelbar ist, wobei das Verbindungsmittel eine im Pumpenkörper (2) drehgelagerte und zum Pumpenkörper (2) über wenigstens ein Dichtelement (17) abgedichtete Anschlusswelle (15) ist, an der der Rotor (5) lösbar angeordnet ist.

Figure imgaf001
An eccentric screw pump, comprising a pump body with a relative to the pump body rotatable screw-like rotor which is coupled via a connecting means with a drive motor, via which the rotor is rotatable, wherein the connecting means rotatably mounted in the pump body (2) and to the pump body (2) via at least a sealing element (17) sealed connection shaft (15), on which the rotor (5) is detachably arranged.
