What Are Enerpac Hydraulic Air Pumps?

Enerpac air-driven pumps are pneumatic-hydraulic systems that use shop or field air (typically 80–120 psi) to pressurize hydraulic oil and power tools or cylinders. Key features include:

• Pressure output up to 10,000 psi (700 bar)

• Foot or hand-operated models for single-acting cylinders

• Remote pendant controls for larger pump units

• Built-in air regulators and pressure relief valves

• Various reservoir sizes, from portable to large-capacity

Air pumps are available in single-speed or two-speed versions, with optional low-noise designs for quieter operation in controlled environments.

Where and How Are They Used?

Enerpac Hydraulic Air Pumps are ideal in applications where compressed air is available but electrical power is limited, risky, or impractical. Common uses include:

• Maintenance and repair shops – Powering hydraulic presses, cutters, and spreaders

• Offshore oil & gas platforms – Hazardous area lifting and torqueing

• Construction sites – Running jacks, tensioners, and lifting equipment

• Utilities and mining operations – Valve actuation and cable cutting

• Manufacturing lines – Operating hydraulic fixtures and tools

• Underground environments – Tunnel boring machine (TBM) maintenance

Because they generate hydraulic power without sparks or heat, air pumps are ideal for flammable or explosive zones.

Accessories and System Components

Enerpac Air Pumps are compatible with a full line of hydraulic components and accessories, including:

• Single-acting and double-acting cylinders

• Quick-connect hoses and couplers

• Remote control pendants or foot pedals

• Hydraulic manifolds for multi-tool control

• Pressure gauges, filters, and lubricators

• Mounting brackets or carts for mobility

Larger air pump systems can also be integrated into hydraulic torque wrench kits, tensioning rigs, and lifting setups.
