Abstract

Es wird eine rotierende Verdrängerpumpe vorgestellt mit wenigstens zwei synchron zueinander angetriebenen Verdrängerkörpern, welche an zugeordneten Arbeitswellen (40,41) angeordnet sind, wobei die Arbeitswellen (40,41) durch ein Synchrongetriebe miteinander gekoppelt sind. Die Verdrängerpumpe zeichnet sich dadurch aus, dass sie ein Gleichrichtgetriebe (30) umfasst.A rotating displacement pump is presented with at least two displacement bodies driven synchronously with one another, which are arranged on associated working shafts (40, 41), the working shafts (40, 41) being coupled to one another by a synchronous gear. The positive displacement pump is characterized in that it comprises a rectifying gear (30).
