POWER SUPPLIES

The Hydraulic Systems Division's facility in Wiesbaden, Germany designs and manufactures hydraulic power supplies (HPS) for aerospace and derivative markets. Our HPS product line is ideally suited for applications where a highly integrated and compact hydraulic system is needed.

 

The HPS is a completely self-contained, compact, gearbox-driven, or AC/DC electric motor-driven device that fully integrates the hydraulic pump with the filters, pressurized and un-pressurized reservoirs, switches, transducers, and ground support couplings. This compact and robust unit provides the full functionality of a conventional hydraulic system for conformance to unique weight and space constraints.

 

Standard and custom units are available for a variety of applications.

 

Applications

  • Most commercial, military, and general aviation aircraft
  • Unmanned aerial vehicles
  • Space vehicles

 

Technical Highlights

  • Variable displacement axial-piston-type pump designs with pressure compensation
  • Fixed-displacement axial-piston-type pump designs
  • Phosphate ester-based fluids and hydrocarbon-based (MIL-PERF-87257, -83282, -5606, MIL-L-23699) operating fluids
  • Pressure rated up to 3000 (207 bar)
  • Flows rated up to 6.0 GPM (22.7 l/min)
  • Speeds up to 10,000 rpm
  • Soft cut-off control available providing constant horse power
  • Solenoids, depressurization valves, and/or blocking pistons available to reduce operating torque
  • Low inlet impeller functions available for improved system operational efficiency
