Abstract

Die Erfindung betrifft eine Pumpe mit einem torusförmigen Pumpengehäuse (2) und mit einem schneckenförmigen Pumpenlaufrad (3), das mit einem inneren Laufradteil (7) in das Pumpengehäuse (2) hineinragt und mit einem äußeren Laufradteil (8) heraussteht. Im Bereich der Schneckenumfangskante (9) des Laufradteils (8) ist wenigstens eine Schlagleiste (15, 16) mit einer Schlagleistenkante (17, 18) zur Verarbeitung von Abwässern angebracht. Erfindungsgemäß ist die Schlagleistenkante (17, 18) und/oder die Schneckenumfangskante (9) mit einer Kantenstruktur mit Vertiefungen (19, 25) oder Erhebungen (20, 26) versehen als Hindernisse für eine Zerkleinerung von durch das äußere Laufradteil (8) vorbeibewegter Feststoffe. Damit wird eine solche Pumpe insbesondere zur Verarbeitung biologischer Reststoffe für eine Verwertung in Biogasanlagen einsetzbar.
