HYDRAULIC TEST STAND ELECTRIC MOTOR DRIVEN 11 GPM AT 3000 PSI, MAX OPERATING PRESSURE 4500 PSI

MAIN FEATURES:
Hydraulic Test Stand mounted on a trolley (steel structure) equipped with four super elastic wheels, two of which on rotating plate. A towing bar can be installed as optional device.
Axial piston type, high pressure, electric motor driven pump with variable displacement and adjustable working pressure up to 11 GPM at 3000 psi or 7 GPM at 4500 psi.
High Pressure 3 μfilter on delivery line equipped with electrical differential pressure switch for filter clogged indication.
Submerged cartridge suction filter 90 μ.
Stainless Steel reservoir, externally painted, volume 110 litres about, operative capacity 70 litres, equipped with inspection hole, oil level visual indicator, drain valve, filling and drain port, suction and return port.
The HTS may be used with aircraft reservoir or test stand reservoir, throughout a 4 ways valve 3 position.
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 request Skydrol fluid.
Proportional electric valve, with by-pass function, to set and control the max working pressure.
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 the return line the back pressure can be adjusted.

INSTRUMENTATION:
H.P. gauge, branch "A", F.S. 6000 PSI, Ø150 mm, accuracy 0,6% f.s., case filled with silicon oil for low temp.
H.P. gauge, branch "B", F.S. 6000 PSI, Ø150 mm, accuracy 0,6% f.s., case filled with silicon oil for low temp.
L.P. gauge, return pressure, F.S. 160 PSI, Ø100mm, accuracy 0,6% f.s., case filled with silicon oil for low temp.
Flowmeter, LPM or GPM and Thermometer, °C digital indication.
Oil level sight indicator. Clogged filter indicator. Hour-counter.

ELECTRIC MOTOR:
Power rating 12 KW.
Power Supply: from 200 to 230 Vac 50/60HZ 63A or from 380 to 440 Vac 50/60 Hz. 32 A, threephases + GND

OPTION:
The test stand (DLP version) is equipped with a Laser Particle Counter (P/N KLP-120), for continuous monitoring the hydraulic fluid, without sampling it, for presence of particles and/or water presence inside the fluid.
