Air Driven Hydraulic Pump unit

1. Hydraulic Pump for CNC tooling fixture. 
2. Use air to drive hydraulic pump. 
3. Also for hydraulic pressure supply system. 

It uses air to drive hydraulic pump. Once outlet hydraulic pressure reached setting pressure, it will stop driving and wont waste energy. If the outlet pressure is reducing, it will add automatically. It can maintain pressure for one year. It is used for slide lock, feeder, stick release and hydraulic pressure supply system which needs to maintain pressure for a long time but less operate.
