Air Hydraulic Pumps: The Industrial Workhorse
Air hydraulic pumps, also known as air over hydraulic pumps or pneumatic hydraulic pumps, are versatile power units that convert compressed air into high-pressure hydraulic fluid. This unique combination delivers exceptional force in a compact, efficient package.
High Power Density
Generate extreme hydraulic pressure with minimal air input, making them ideal for heavy-duty applications where space is limited.
Precision Control
Offer fine-tuned pressure regulation for tasks requiring exact force application, from delicate assembly work to high-stress operations.
Safety & Reliability
Designed with fail-safe mechanisms and durable components, ensuring consistent performance in harsh industrial environments.
How Air Powered Hydraulic Pumps Work
Air hydraulic pumps operate on a simple yet powerful principle: using compressed air to drive a piston, which in turn pressurizes hydraulic fluid. This fluid is then directed to an actuator, such as a cylinder or motor, to perform work.
Air Input
Compressed air enters the pump, driving a piston through a cylinder.
Hydraulic Pressure Generation
The piston's motion pressurizes hydraulic fluid in a separate chamber.
Fluid Distribution
Pressurized fluid is directed to the hydraulic tool or cylinder via high-pressure hoses.
Work Execution
The hydraulic force generated performs tasks such as lifting, pressing, or clamping.
Pressure Ratios
Air hydraulic pumps typically offer pressure ratios from 10:1 to 100:1, meaning they can generate hydraulic pressures 10 to 100 times greater than the input air pressure.
Essential Parts of an Air Over Hydraulic Pump
Understanding the core components of an air hydraulic pump helps in selecting the right model for your application and ensures proper maintenance.
Air Motor
Converts compressed air into mechanical motion, driving the hydraulic pump. Available in various sizes to match specific power requirements.
Hydraulic Pump
Generates high-pressure hydraulic fluid using the mechanical input from the air motor. Available in gear, piston, and vane configurations.
Pressure Regulator
Controls the output pressure of the hydraulic fluid, ensuring precise and consistent performance across different applications.
Reservoir
Stores the hydraulic fluid, ensuring a continuous supply during operation. Available in various capacities to suit different system requirements.
Valve Block
Directs the flow of hydraulic fluid to the appropriate actuators and includes safety valves to prevent over-pressurization.
Control Panel
Provides operators with controls to start/stop the pump, adjust pressure, and monitor system performance.

Extending the Life of Your Air Hydraulic Pump
Proper maintenance ensures your air hydraulic pump operates at peak efficiency and reliability for years to come.
Regular Fluid Checks
Monitor hydraulic fluid levels and quality. Contaminated or low fluid can cause pump failure. Replace fluid according to manufacturer recommendations.
Air Filter Maintenance
Clean or replace air filters regularly to prevent debris from entering the pump, which can cause wear and reduce efficiency.
Seal Inspections
Check seals and gaskets for signs of wear or leaks. Damaged seals can lead to fluid loss and reduced pump performance.
Lubrication
Ensure moving parts are properly lubricated as per manufacturer guidelines to reduce friction and prevent premature wear.
Pressure Checks
Regularly verify pump pressure output to ensure it meets specifications. Inconsistent pressure may indicate internal issues.
