Abstract
A tube pump for conveying liquid or viscous media, with a pump head on which at least two pump rollers are arranged which latter can act in succession on a tube, carrying the medium to be conveyed and located in the tube bed, in such a way that the medium is transported by squeezing the tube tightly, wherein the tube bed and the tube are fashioned so that the tube can be inserted in the tube bed in only one direction. This can be achieved by using end pieces of differing geometric forms and/or sizes, and/or providing that one end piece is magnetic and providing a magnetic sensor in the corresponding socket of the tube bed.
