Send us the cylinder or tool model, required oil volume and available compressed-air supply and Northland can help match the complete setup.
Compressed Air In. High-Pressure Hydraulic Power Out.
Enerpac air hydraulic pumps use compressed air to generate hydraulic pressure for cylinders and industrial tools. Pump families differ significantly in oil flow, reservoir capacity, compressed-air demand, valve configuration and control method.
Why Use an Air Hydraulic Pump?
Air hydraulic pumps convert compressed-air energy into high-pressure hydraulic oil flow. They provide powered hydraulic operation without an electric motor and can be particularly useful in shops, plants, production environments and field-service applications where compressed air is readily available.
Compressed air powers the pump, allowing hydraulic operation without a conventional electric pump motor.
The main PA, PAM, Turbo II, XA and ZA4 pump families operate at pressures up to 10,000 psi.
PA, PATG and XA pump designs provide foot-control options so an operator can keep both hands available for the work.
Depending on pump and valve configuration, Enerpac air pumps can operate either single-acting or double-acting hydraulic cylinders and tools.
Options range from portable foot pumps to large ZA4 modular air hydraulic power units with substantially higher oil flow.
Treadle, manual valve, air pendant and modular directional valve configurations allow the pump to match different operating requirements.
Compare Enerpac Air Hydraulic Pump Families
Open each pump family to compare hydraulic flow, oil capacity, compressed-air requirements, cylinder compatibility, control method, current models, common applications and industries.
Two pumps can both be rated for 10,000 psi and perform very differently. Compare usable oil volume, oil flow under load, air pressure, required SCFM, valve configuration, cylinder type, desired speed, control method and operating environment before selecting the pump.

Where Air-Over-Hydraulic Pumps Are Used
Air hydraulic pumps are used where compressed air is available and high-pressure hydraulic force is required. The applications below are common examples and are not intended to limit other suitable uses.
Power hydraulic presses for assembly, forming, straightening, bearing work and industrial maintenance.
Operate compatible hydraulic cylinders for controlled lifting and positioning.
Power fixtures, hydraulic clamps, positioning systems and high-force production tooling.
Provide portable hydraulic power for mining and material-handling equipment service.
Operate hydraulic cylinders and tools during heavy-equipment repair and component positioning.

Enerpac air hydraulic pumps may also be used in other lifting, pressing, clamping, pulling, pushing, positioning, production, repair, bolting and maintenance applications where hydraulic pressure, oil flow, usable oil capacity, valve configuration and compressed-air supply are suitable.
Your Compressor Is Part of the Hydraulic System
An air hydraulic pump can only perform properly when the compressed-air system can supply the required pressure and airflow while the pump is operating.
Check actual pressure at the pump while air is flowing.
Confirm compressor and piping capacity against the exact pump's air consumption.
Long or undersized air lines, fittings and regulators can cause pressure drop and reduced pump performance.
Several pump families recommend a regulator-filter-lubricator to provide clean, controlled air.
Adequate compressed air does not compensate for a reservoir that is too small for the cylinder.
Higher-cycle applications may require greater oil flow, larger reservoirs or a heavier-duty pump family.

This helps determine pressure, oil volume and cylinder action.
Confirm the pressure class required by the cylinder or tool.
Pump usable oil capacity must cover the required cylinder movement.
Hydraulic flow determines how quickly a cylinder of a given area will move.
This determines the directional-valve function required.
Provide dynamic air pressure available while the pump is running.
Airflow can be just as important as air pressure.
Foot control, manual valve or remote pendant may determine the most suitable pump.
