Abstract

Stator (10) für Exzenterschneckenpumpen (2) mit einem Statormantel (16) für einen mit mindestens einem Bund (18) versehenen elastomeren Körper (20) zur Aufnahme eines Rotors, wobei der Bund (18) in einer Ausnehmung zwischen Statormantel (16) und einem Anschlusskörper (4, 6) angeordnet ist, bei dem die Fixierung des elastomeren Körpers (29) im Statormantels verbessert werden soll. Dazu weist erfindungsgemäß der Statormantel (16) zumindest an einer Seite stirnseitig offene Hohlräume (50), Ausnehmungen und/oder Erhebungen auf.
