I scored a Nugier H25-7 air over hydraulic 25 ton press for $150. This is one heavy duty sucker. It almost killed me to unload this beast by myself. I shouldn't need much to get it pumping. The air part moves the ram but the hand pump doesn't build pressure. It seems as though it needs a cup in the pump or something. Anybody out there have one of these? An owners manual and a parts list would be great. Time for some cleanup and paint.
. I paid Nugier to rebuild the pump because somebody was inside it before I got it and they don't have any diagrams for this style of pump. With no way to know if I was putting it together right I thought this was the way to go. I rebuilt the ram and it holds pressure. Its not a true air over hydraulic its a hydraulic with an air blow down valve. It works great, blows down to the work then you pump to build pressure. Here are some pics.
