How to make homemade PUMP 60 BAR

Unread postAuthor: keks2033 » Sat May 14, 2016 1:57 am

So I shake pump 50 bar to their guns. It is easy to make and easy to fix. I use this pump for more than six months, everything works.

Many thanks. Which valve is shown in a photo of your profile? It is a variant of the piston of the valve? Do you have information on this valve?

it's a variant of quick dump valve (QDV). Technician1002 have posted cannons here using that type of valve.. if i remember it's hes design actually. It's a balanced valve that is actuated mechanically by pulling the piston with pull rod. After you pull the piston over the air inlets the air pressure kicks in and opens the valve very fast.

Thank you very much for your answer. I thought it was a new valve. I have already done so.
