Abstract

Exzenterschneckenpumpe für die Förderung von Dickstoffen, insbesondere von Flüssigmörtel. Die Exzenterschneckenpumpe umfasst einen aus einem Elastomer bestehenden, einen nach Art eines zwei- oder mehrgängigen Steilgewindes (20) geformten Pumpenhohlraum (14) aufweisenden Stator (12) und einen mit radialer Exzentrizität (e) den Pumpenhohlraum (14) durchgreifenden, motorisch angetriebenen, nach Art eines Steilgewindes (22) geformten Rotor (16). Der Pumpenhohlraum (14) des Stators (12) weist dabei einen Gewindegang mehr als der Rotor (16) auf. Um eine gute Durchmischung mit hohem Luftporenanteil zu erhalten, wird vorgeschlagen, dass der Pumpenhohlraum (14) am druckseitigen Ende des Stators (12) in eine Mischkammer (28) mündet, in welche ein drehfest mit dem Rotor (16) verbundenes Mischelement (30) eingreift.
