Engineering Overview & Structural Features

The HPA Series Pneumatic-Hydraulic Air Pumps convert standard shop compressed air (6 to 10 Bar / 85 to 145 PSI) into high-efficiency 700 Bar (10,000 PSI) hydraulic fluid power. Engineered for intrinsically safe, spark-free operation in explosive or flammable environments, the series delivers up to 0.8 L/min no-load flow with rapid load advancing. Featuring heavy-duty construction across polymer, die-cast aluminum, and welded steel reservoirs (1,600 to 4,500 cm³), dual air and oil filtration screens, high-attenuation exhaust mufflers, and hands-free 3-position treadle pedals or remote handheld pendants, the HPA Series provides ergonomic and continuous fluid delivery for single-acting cylinders, torque wrenches, and pullers.

CORE ENGINEERING ARCHITECTURE & TECHNICAL SPECIFICATIONS

HEAVY-DUTY MODULAR BUILD & EASY MAINTENANCE

Robust industrial construction engineered for extended operating life, severe shop duty, and rapid field maintenance. Multi-material reservoir options include impact polymer, cast aluminum, and heavy welded steel.

AIR EXHAUST MUFFLER & QUIET OPERATION

Integrated high-efficiency air exhaust muffler attenuates reciprocating pneumatic exhaust noise, ensuring low-decibel, quiet operation compliant with occupational safety standards in enclosed plant spaces.

DUAL AIR & OIL CONTAMINANT FILTRATION

Pumps incorporate both air intake filtration elements and fine internal oil reservoir filter screens, mitigating particulate contamination risks and extending valve and seal service intervals.

INTERNAL LOAD LIMITING & TREADLE / REMOTE CONTROL

Internal pre-set safety relief valve guarantees overload protection. Available with hands-free 3-position foot treadles (Advance, Hold, Retract) or remote handheld pendant controls (HPA-005) for operator isolation.

PNEUMATIC ACTUATION SCENARIOS & HAZARDOUS ENVIRONMENT USAGE

EXPLOSIVE & SPARK-FREE ZONES

100% air-driven operation delivers spark-free 700 Bar fluid power in chemical plants, oil refineries, paint spray booths, and grain storage facilities where electric motors pose hazards.

HANDS-FREE PRODUCTION PRESSING

The 3-position treadle foot pedal allows technicians to keep both hands free to position, hold, and align workpieces in shop presses, crimping stations, and bending fixtures.

DISTANCE OPERATION VIA REMOTE PENDANT

HPA-005 handheld pendant allows operators to stand safely clear of heavy structural loads during high-tonnage jacking, proof load testing, and pipe flange realignment.
