OGD-2 Series Pneumatic Hydraulic Pump

If you’d like to learn more about other models, please contact our customer service team.

Features & Functions

• Pressure can be adjusted through a manual hydraulic pressure control valve or a pneumatic control valve.
• Air-driven operation, especially suitable for explosion-proof applications.
• Capable of reaching the preset final pressure.
• Automatic pressurization by the pump.
• Long-term pressure holding with no additional energy consumption.
• Ensures the medium will not overheat during pressure holding.
• Easy installation and low maintenance cost: only need to connect air source, inlet line, and pressure line to work.
• Reliable operation with low maintenance cost and low operating noise.

Product Advantages

• Compact structure, low cost, and high efficiency.
• Driven by compressed air or inert gas; pressure can reach 600 MPa.
• OGD-2 series produces 2× output pressure compared with OGD series under the same driving air pressure.
• Aluminum alloy gas drive section with oxidation black finish; liquid end material selectable by medium.
• Imported high-quality seal set to ensure pump performance.
• Automatic operation: starts when pressure drops and compensates pressure automatically.

Working Temperature & Recommended Drive Air Quality

• Working temperature: Standard operating temperature range is -20°C to +60°C. (Below 0°C, ensure the driving air source is dry and clean.)
• Recommended drive air quality (PNEUROP 611/1984):
• Air quality class: 3–4
• Particles: max particle size 5 μm, max particle concentration 5 mg/m³
• Dew point / water content: +10°C: 9.4 g/m³, +2°C: 5.6 g/m³
• Oil content: 1.0–5 mg/m³
• Note: Continuous operation with humid gas may cause icing. It is recommended to install a water separator or dryer and use a lubricator to extend seal life.
