Abstract

Die Erfindung betrifft eine Pulverförderpumpe (1), insbesondere für eine Pulverbeschichtungseinrichtung, mit einem Arbeitsraum (5) mit einem veränderlichen Arbeitsraumvolumen, einem in den Arbeitsraum (5) mündenden Pulvereinlass (6) zum Einsaugen von Pulver (2) in den Arbeitsraum (5), einem aus dem Arbeitsraum (5) ausmündenden Pulverauslass (9) zum Ausstoßen des in dem Arbeitsraum (5) befindlichen Pulvers (2), sowie einem beweglichen Kolben (12), der eine Begrenzungsfläche des Arbeitsraums (5) bildet und das Pulver (2) bei einer Aufwärtsbewegung durch den Pulvereinlass (6) in den Arbeitsraum (5) einsaugt. Es wird vorgeschlagen, dass der Kolben (12) pneumatisch direkt angetrieben ist.
