Abstract

Eine auswechselbare Pumpkartusche (200) für eine Membranpumpe weist einen Basiskörper (300) und einen Deckkörper (500) auf. Zwischen dem Basiskörper und dem Deckkörper ist eine Pumpmembran (410) angeordnet. Die Pumpmembran und der Deckkörper begrenzen gemeinsam einen Arbeitsraum. Lateral von der Pumpmembran sind zwischen dem Basiskörper und dem Deckkörper ausserdem Ventilklappen (420, 430) eines Einlassventils und eines Auslassventils angeordnet. Der Basiskörper und der Deckkörper weisen jeweils zu den Ventilklappen weisende Oberflächen auf. In den genannten Oberflächen sind Vertiefungen ausgebildet, die lateral verlaufende Fluidkanäle (521, 531) zwischen dem Einlassventil, dem Arbeitsraum und dem Auslassventil bilden. Zusätzlich kann eine Filtermembran (600) in der Pumpkartusche integriert sein. Zur Verbindung mit einem Pleuel eines Antriebsmoduls kann die Pumpmembran eine sacklochartige Öffnung (412) aufweisen.
