The invention relates to a pump for simultaneously conveying a plurality of identical or non-identical fluid media which are located in separate conveying routes, with the aid of a drive, a plurality of conveying routes which comprise elastomeric hoses that can each be shut off by an inlet and an outlet valve being arranged axially parallel to one another on a circle in whose centre a motorically drivable eccentric is rotatably mounted, and the eccentric in its rotary movement successively applying to the elastomeric hoses a force, by means of which a discharge pressure actuating the valves builds up and decays in each hose with the rotary frequency of the eccentric. Arranged at the inlets and outlets of the conveying routes there is a duct system which connects a plurality of conveying routes at a time. The elastomeric hoses forming the conveying routes in each case comprise an elastomeric silicone hose whose cross-sectional shape can be altered in the plane of action of the eccentric by means of an adjustment device. The conveying routes arranged circularly and axially parallel to one another are disposed, together with the motorically drivable eccentric, in a cage in whose top and bottom section, which are linked to one another by means of supports and struts, the duct system connecting a plurality of conveying routes and the inlet and outlet valves delimiting a conveying route in each case are integrated.
