Forgot to answer the question - those pumps are very high-tech equipment, because of the materials that are used to make them, for example, plungers are made of some kind of ceramics. The huge water pressure creates very intensive fatigue wear to material, and highly specific know-how in material properties is required to deal that (note the the thickness of walls for the cilinder, in which the plunger is moving - outer diameter is ~12 cm, while inner is ~1cm). So I do not see any way to create a DIY pump for waterjet cutting. One can easily build the machine construction, but I am convinced that pump, high-pressure tubing and cutting head are impossible to be created in a DIY process. Just like Dave says, it is pretty simple from the process point of view, but what I have seen in my machine is that it is very complex to be replicated from the materials' point of view.
