Hey Henry, try and "right click" on your mouse, and look for "translate" on the little screen that pop's open ,click that and see what come's up. I like google for translation (web browser) hope this help's.
I had to translate each item. I did gather that the cylinder's are stainless steel, and rebuildable. The valves look like a rotary version, still trying to figure out which style is easier to build? The pump look's neat, not much info?
