Abstract

Die Erfindung betrifft eine Dosierpumpe, umfassend eine auf einer Basisplatte (1) angebrachte Klemmeinrichtung (2) für Spritzen (3), deren Kolben an auf der Basisplatte verschiebbaren Betätigungselementen (5) einhängbar bzw. befestigbar sind, wobei den Betätigungselementen (5) gegenüberliegend auf der Basisplatte eine Steuereinrichtung (6) angeordnet ist, mit der die Spritzenzylinder der Spritzen (3) verbunden sind und die zum Umsteuern von Saug- und Druckleitungen mit einer Antriebseinrichtung (13) gekoppelt ist, welche die Betätigungselemente (5, 5') für wenigstens zwei Spritzen (3, 3') gegenläufig hin- und herbewegt.
