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. The invention relates to a positive displacement pump with two intermeshing rotating bodies in a hollow cylinder. The very compact pump with affordable mechanical Prerequisites and advantageous properties is suitable for liquid and gaseous Pump media, also achieves high pressure performance with high stability in one step, enables precise dosing, is low in pulsation and self-priming, can be gentle promote.

Das breite Spektrum an vorteilhaften Eigenschaften macht das Pumpenprinzip vielseitig einsetzbar. The wide range of advantageous properties makes the pump principle versatile.
