Hydraulic piston pump P12, P23, P55

manual

This single-acting pump is constructed entirely from metal and cannot burn through in welding environments. Less flex is provided by the formed metal handle, reducing operator fatigue. Pumps can be filled in either a vertical or horizontal position by the convenient fill port on P23 and P55. Over-pressurizing of the reservoir is prevented by the fill cap seal which acts as a safety valve. Loads are prevented from drifting down by the relief valve inboard of the check valve. Loads can be slowly metered down by the large valve knob.
