Is there people on this board that have made a hydraulic ram pump for themselves or for a friend? I've been wanting to build one for ages and finally it is on my next-projects-list I do not have a creek or a river or similar, this is just for fun and learning, because the time I find a place that has a natural water source, I'll bolt this kind of thing there to supply me with water 24/7.
I just love watching and listening to the slow kachunk --- kachunk --- kachunk sound and seeing a pump operate without electricity or fuel and the fact that it has two moving parts.
I recently went to this website and that was my deal breaker there, the waste valve design that the AIDFI ram pumps also use. I'm planning on making something like the AIDFI demo ram pump, so the body will be something like 60 mm wide or so.
I think I'll go and find me a stainless steel door hinge with a suitable size or if I can't find one, then its back to the machine shop to make some other hinge idea.
Materials I'll be needing are probably some heavy wall 60 x 60 tubing, some angle iron for the feet, stainless steel plate or cut-off from a bar for the valves, piece of inner tire or a rubber sheet, some round pipe, some round pipe or the like to make the flanges and then a handful of nuts and bolts to fudge it together But first, let me take a self..err...make a CAD drawing to figure out the needed sizes.
