  • the advantages of the previously described pump are, in particular, that the pump tubing is preassembled outside the pump, i. can be attached to the hose holder. Such a manufacturing step can be largely automated and brings significant advantages in terms of manufacturing costs, precision and durability. After assembling the pump, it is only necessary to click on the two connection elements provided with the connecting hoses on the hose holder so that the pump is hydraulically ready for operation. Such a pump can be assembled with virtually no tools with little effort. If the projections 13a, 13b are formed on the outside substantially smooth and not barb-like, the pump tubing can possibly be replaced very quickly and easily by the connection element 4 is replaced with the glued tubes 6 as a whole.
