Hydraulic pump and valve ?
Any information on what hydraulic pump to buy or stay away from? looking to build a old Arrow Master 1350 hydraulic hammer, and would like to make it hydraulic. But i do not have a clue on ml per min required? been looking at the liembach pumps, And there price list has 12v15,35,40 ? is that the ml per min and volt ? and picture 72 is the valve to make it auto up/down, any idea of how to replicate that? Just a single control valve with no servo just a servo horn on it hitting the two fingers ?
