Werner Weitner air hydraulic pumps can be used effectively in much case where high pressure is necessary and do not need much maintenance that means lower operating costs. WL series pumps produce 700 bar hydraulic output with only 5 bar air input. WL pumps can be used securely in several fields such as; operating hydraulic cylinders, pullers, presses…

These pumps are controlled by a foot pedal. When pedal is pressed from back side, the air engine starts to pump oil until you release the pedal to stop pumping. When pedal is pressed from front side, pressure relief operation could be completed. For security conditions, WL series hydro-pneumatic pumps are equipped with pressure relief valve just as other Weitner pumps. When pressure reaches the adjusted value, exceeding oil is discharged to tank due to reduce risks.

Air hydraulic pumps work more silently according to electrical or gasoline power units and can be used securely at any gaseous or flammable places. WL pumps also can be used as double acting with the help of a way control valve.
