Abstract

Stator einer Exzenterschneckenpumpe zur Förderung von Putz, Mörtel, Estrich und anderen in der Bautechnik benötigten Medien mit einer zwei - oder mehrfach gewendelten Elastomerauskleidung, wobei das Verhältnis der dicksten Stellen (S1) zu den dünnsten Stellen (S2) der Elastomerauskleidung (3) im Bereich von 3 bis 8 liegt.

Figure imgaf001
Stator of an eccentric screw pump for conveying plaster, mortar, screed and other media required in structural engineering with a two or more coiled elastomer lining, the ratio of the thickest points (S1) to the thinnest points (S2) of the elastomer lining (3) in the range from 3 to 8 lies.
