Ageing and endurance test bench for hydraulic components. ATEX-ceramic enclosure for testing with hazardous fluids over a temperature range from -70°C to 220°C, 30 to 95% hygrometry. Dynamic control of fluid pressure in the circuit (pulsed pressure). Continuous monitoring of product sealing and continuous measurement of leakage levels. Possibility of adding a vibratory load with a vibrating pot and/or a mechanical load (twist or deflection) with the addition of dedicated actuators. Fluid flow and temperature control with pressure drop monitoring.
