High Pressure Air Hydraulic Pumps
An air hydraulic pump is a specialized compressed-air-driven power unit designed to generate extreme hydraulic pressures for industrial bolt tensioning and torque tooling.
Heavy-industry operators routinely select air hydraulic pumps over manual hand pumps to execute high-volume flange tensioning with significantly faster cycle times and far less manual physical exertion.
Built to operate optimally in rugged on-site conditions, this high-pressure power source delivers the consistent fluid delivery required to guarantee uniform, repeatable mechanical load retention across critical joints.
Tool Features:
-
- Premium Internal Pump Unit: Incorporates high-specification air-driven internal mechanisms for exceptionally stable pressure buildup.
- Stainless Steel Oil Tank: Outfitted with a corrosion-resistant steel fluid reservoir to prevent structural fluid contamination.
- Heavy-Duty External Roll Cage: Enclosed in a rugged steel frame that protects vital components from accidental field impacts.
- Safety Pressure Relief Valve: Features an integrated mechanical bypass switch to protect operators from over-pressurisation hazards.
- Inline Air Lubricator Assembly: Automatically feeds vital lubrication to internal air drive pistons, extending tool service life
Benefits:
-
- Zero Electrical Ignition Risk: Powered completely by compressed air, eliminating dangerous electrical sparks in hazardous oil, gas, or mining zones.
- Minimised Maintenance Downtime: Delivers highly rapid multi-tool pressure cycles, drastically accelerating critical plant turnaround schedules.
- Prevents Operator Fatigue: Eradicates the gruelling physical labour of manual leverage bar pumping, promoting a safer, more productive workplace.
- Perfect Clamping Repeatability: Retains consistent hydraulic outputs, ensuring every interconnected stud achieves its identical pre-calculated tension.
- Highly Economical Power Draw: Holds maximum target pressures flawlessly without consuming extra operational energy when stalled in sequence.
