AHP3500 Air-Driven High Pressure Pump
AHP3500 Air-Driven High Pressure PumpThe AHP3500 is a heavy-duty air-operated hydraulic pump independently developed by Ailesen (Changzhou) Power Technology Co., Ltd. It converts compressed air power into ultra-high hydraulic pressure, specially designed for ultra-high-pressure industrial scenarios that prohibit electric ignition sources. Driven entirely by air, it features explosion-proof performance, stable pressure boosting, automatic pressure hold and stop functions, and serves as the core power source for fuel injector test benches, bolt tensioners, high-pressure hydrostatic testing, marine diesel maintenance and calibration equipmentaileseng.c...2. Core Working PrincipleCompressed air pushes the large-area air piston to reciprocate continuously, driving the small-diameter high-pressure plunger to compress hydraulic oil for pressure amplification. Once the preset hydraulic pressure is reached, the pump automatically suspends cycling and maintains constant pressure without continuous air consumption; it restarts automatically when system pressure drops, realizing unattended constant-pressure operation with low energy waste.3. Key Technical SpecificationsMax Hydraulic Output Pressure: 350 MPa (3500 bar / 50,760 psi) at 0.7 MPa input air pressure; 280 MPa at 0.6 MPa air supplyaileseng.c...Cycling Speed: ~400 cycles per minute under 0.7 MPa air inputOil Flow Rate: Minimum output flow 0.45 L/minAir Consumption: Approx. 1050 L/min at 0.6 MPa air pressureBuilt-in Oil Tank: 8 L capacityPort Thread Standard: Air inlet G1/2 internal thread; high-pressure oil outlet G1/4 internal threadOverall Dimension: 490 × 430 × 480 mmNet Weight: About 30–32 kgStandard Equipments: Dual glycerin-filled vibration-resistant pressure gauges (air pressure + hydraulic pressure), pressure regulating valve, quick pressure relief valve, integrated filter-lubricator unit, portable carrying handle and sturdy metal frame4. Outstanding Product FeaturesIntrinsically Safe & Explosion-ProofNo electric motor or electrical components, suitable for flammable, explosive, damp or underground working environments such as chemical plants, oil & gas fields and ship engine rooms.Ultra-High Stable Pressure OutputPrecise pressure amplification structure delivers steady ultra-high pressure with minimal pressure fluctuation, supporting high-precision calibration and testing work.Automatic Pressure Holding & Energy SavingAuto-stop upon target pressure, auto-restart for pressure compensation; avoids idle cycling and greatly reduces compressed air consumption.Simple Operation & Easy MaintenanceIndependent control knobs for air pressure adjustment, high-pressure output and quick pressure release; modular pump head design for fast disassembly, cleaning and part replacement without professional tools.Durable Heavy-Duty StructureCore pressure-bearing components adopt high-strength alloy steel with precision grinding and anti-leakage sealing kits, resisting long-time continuous high-load operation; integrated anti-vibration structure lowers running noise.Compact Portable LayoutIntegrated oil tank and pump body with top carrying handle, easy to move between workshops, test benches and on-site maintenance locations.5. Main Industrial ApplicationsMarine diesel injector test & calibration benchesUltra-high-pressure bolt tensioning for petrochemical pipelines, pressure vesselsHydrostatic pressure testing of high-pressure pipes, valves and hydraulic componentsLaboratory high-pressure fluid pressurization and pressure calibrationMining, offshore and shipyard explosion-proof high-pressure hydraulic operationsHydraulic power supply for ultra-high pressure clamping tools6. Operating Advantages Compared with Electric PumpsZero ignition risk, fully compliant with explosion-proof site regulationsLighter and more flexible for field mobile maintenanceNo overload burnout risk; self-protects automatically under pressure holding statusLower long-term operating cost by saving compressed air and maintenance expensesShort Version (for Catalogue / Product Card)AHP3500 Air-Driven Ultra High Pressure Hydraulic PumpA pneumatic power unit reaching max 350 MPa hydraulic pressure, explosion-proof, auto pressure hold, compact integrated design. Widely used for injector testing, bolt tensioners and hydrostatic pressure test in marine, oil & gas and chemical industries. Stable output, easy operation and low maintenance cost.07-092026

Hydraulic Jack
Hydraulic Jack Test of 2200 Bar Hydraulic JackApplicable engine type：S65ME-C, G70ME-C, K80ME-C, S80ME-C, G80ME-C, K90ME-C, S90ME-C, G95ME-C, K98ME-C, K98ME.1. Safety measures In case of malfunctioning hydraulic jacks or hoses 1.1 Always keep clear of area above the pressurized hydraulic jack during use. Broken studs or malfunctioning jack can eject! 1.2 Bursting hydraulic hose can eject oil into the skin! Always inspect the hose assembly before use. Defective or damaged hose assemblies must be replaced and discarded!1.3 Verify correct engagement of couplings before applying hydraulic pressure1.4 Leaking hydraulic oil can pose a risk in case of skin contact. Always use goggles and oil resistant gloves when working with hydraulic oil.08-142025
