Air Driven Hydraulic Pump Unit



This unit consists of a pump for converting air pressure to oil pressure and a non-leak valve. It is equipped with valves for each pair of hydraulic cirtuits for upper and lower dies.


Use the air drive hydraulic pump. Once the outlet hydraulic pressure reaches the set pressure, it will stop driving which won't waste any energy. Or, it will add the pressure automatically if the outlet pressure is reducing. It consists of the function to keep the pressure continuously.

The circuit control system has the function of check. If there is no pneumatic pressure, the hydraulic pressure will still keep.

Pressure inspection function is provided, which is on-line with the pressure for ensuring work safety.

There are 2 hydraulic control circuits for upper and lower dies respectively.
