ABSTRACT:
A volumetric pump comprising a flexible conduit and roller means for collapsing the conduit to pump liquid therethrough. The conduit is formed to provide a projecting rib to anchor the conduit to an underlying support device. The conduit is formed by forming a flat elastomeric sheet into tubular form, the opposite side edges of the sheet having flanges which are disposed into abutting relation to form the anchoring rib. Preferably, the sheet has a reinforcement imbedded centrally therein. The support may include jaws for clamping the two flange members into abutting relation and saddle elements to insure the desired pumping action by the rollers as they are advanced along the tubular member.
