Overview
RH Aero’s Hydraulic Ground Power Units (HGPUs) provide clean, precisely-regulated pressure and flow for any aircraft hydraulic system—right on the ramp or in the hangar. Manufactured by TEST-FUCHS and distributed worldwide through RH Aero since 2008, the cart-mounted units support 3 000 psi or 5 000 psi systems with single or dual independent circuits delivering up to 60 US gpm. Airbus certification and Boeing COM-8859 approval underpin every model, while a modular options set lets you match power (electric or diesel), filtration and data logging to your operation exact needs.
Use Cases
Supported Aircraft Types:
- Airbus: A320 Family, A330/A340, A350, A380, A300/A310, A400M
- Boeing: 737, 747, 757, 767, 777, 787 (COM-8859)
- Regional & others: Embraer ERJ/E-Jets, Bombardier CRJ & C-Series, Antonov AN-124/148, Sukhoi SSJ100
Typical Maintenance Tasks:
- Functional testing of ATA 29 hydraulic systems
- System flushing, fluid fill/drain and component actuation during heavy checks
- System calibration and diagnostics
- Hydraulic system maintenance and servicing
Benefits
3000 / 5000 psi at up to 60 gpm: One cart services narrow-, wide- and regional-jet fleets without re-rigging.
Single or dual independent circuits: Run symmetrical or split-system tests simultaneously while preventing cross-contamination.
Electric or diesel drive: Choose zero-emission hangar operation or true flight-line autonomy.
Ventilation concept free from Skydrol vapours: Protects technicians and avionics from phosphate-ester mist.
Automatic over-temperature shut-off & anti-cavitation low-pressure circuit: Safeguards pumps and aircraft components during long endurance tests.
User-friendly, weather-proof control panel: Intuitive layout and optional cover keep operation simple in any climate.
Modular options & accessories: Configure each HGPU precisely to your maintenance SOPs
