High Pressure Air Hydraulic Pumps

Model No.: PU-AH / PU-EH Series

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. 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. Technical Specifications: Ideal applications: High-Volume Flange Makeup : Speeding up complex multi-bolt tightening configurations on large structural pipe joints and industrial vessels. Hazardous Hazardous Environments : Operating safely inside explosive oil, gas, or underground mining zones where electrical power is strictly prohibited. Repetitive Plant Maintenance : Executing rapid, continuous tool pressure cycles during busy refinery or power station turnaround schedules. Powering Heavy Tensioners : Supplying stable hydraulic pressures up to 4000 bar to drive multiple interconnected EziJac bolt tensioners and EziTite hydraulic nuts.
