Abstract

Bei einer Schraubenspindelpumpe mit in einem Pumpenlaufgehäuse vorgesehener, von Laufspindeln (30) flankierter Antriebsspindel (10) mit sich berührenden Spindelgängen (13, 33) der Spindeln (10, 30) sind letztere zumindest teilweise mit einer elastischen Schicht (50, 54) versehen, die bevorzugt aus einem Elastomer besteht.
Die elastische Schicht (50, 54) ist außerhalb des Pumpenlaufgehäuses am saugseitigen Ende der Spindeln (10, 30) vorgesehen und bevorzugt napfartig ausgebildet sowie auf ein Ende der Spindel (10, 30) aufgeschoben.
