Abstract

Die Erfindung betrifft eine Verdrängerpumpe mit zwei ineinandergreifend gelagerten Rotationskörpern in einem Hohlzylinder. Die sehr kompakt bauende Pumpe mit günstigen mechanischen Voraussetzungen und vorteilhaften Eigenschaften ist geeignet für flüssige und gasförmige Pumpmedien, erreicht auch einstufig eine hohe Druckleistung bei hoher Standfestigkeit, ermöglicht genaue Dosierungen ist pulsationsarm und selbstansaugend, kann schonend fördern.
Das breite Spektrum an vorteilhaften Eigenschaften macht das Pumpenprinzip vielseitig einsetzbar.
