Hydraulic Test Stand; electric motor driven, 6GPM at 3000 PSI, for hydraulic system test and check for medium/light helicopters and light aircraft.

Suitable for AW109, AW169, BK117, AB212/412

Main Features

Hydraulic Test Stand mounted on a trolley (steel structure) equipped with two super elastic wheels, two fwd castor wheels and an hand bar on the back of the equipment for easily handling.

Axial piston type high pressure electric motor driven pump with variable displacement and adjustable working pressure up to 6 GPM at 3000 psi.

High Pressure 3 μ filter on delivery line.

Submerged cartridge suction filter 90 μ.

Stainless Steel reservoir, externally painted, volume 60 litres about, operative capacity 40 litres, equipped with:

• inspection hole
• fluid level visual sight indicator
• drain valve
• filling and drain port
• suction and return port

Sampling port to check the fluid class (according to NAS 1638).

Ambient working temperature: from -20°C to +50°C.

Working fluid: MIL-PRF-5606, MIL-PRF-83282 or MIL-PRF-87257.

On return line the back pressure can be adjusted.

Mechanical relief valve, to pilot the pump compensator for the adjusting of the actual working pressure.  The HTS is Dual System (2 completely independent branches, each branch composed by one delivery line and one return line), it is possible to operate with different pressures (with the aid of two pressure reducing valves) on both circuits simultaneously. On return line the back pressure can be adjusted.
