HYD
Hydraulic oils
Mineral, synthetic and biodegradable oils, plus industrial hydraulic fluids selected for their grade and operating conditions.
Fluids
Hydraulic and fluid test benches
Reproduce real fluid operating conditions to measure, inspect and validate a component or fluid subassembly.
At a glance
The requirement comes before the machine.
SEM designs each test circuit around the actual fluid, pressure, flow and temperature ranges, as well as cleanliness, hazards and the required results. Generation, regulation, filtration, instrumentation, safety, containment and fluid recovery are engineered as one system to deliver repeatable tests and usable results.
Controlled pressure, flow and temperature
Leak and tightness testing
Cycling and endurance
Filtration and cleanliness control
Data acquisition and traceability
Steel, stainless steel or purpose-selected materials
Fluid compatibility
A bench engineered for the actual fluid.
SEM can assess test equipment for every family of fluid. Compatibility is never assumed: we start from the exact product reference, safety data sheet, temperature, viscosity, cleanliness requirement and process hazards to select materials, seals, pumps, filtration, sensors and the recovery method.
SKY
Skydrol and phosphate esters
Dedicated aerospace circuits using components and materials selected for the exact fluid reference.
AQU
Water and aqueous mixtures
Industrial or demineralised water, water-glycol, emulsions and aqueous solutions for circulation, pressure or cooling tests.
FUE
Fuels and petroleum fluids
Kerosene, diesel, petrol and related fluids following assessment of hazards, containment, ventilation and required equipment.
THM
Heat-transfer fluids and lubricants
Lubricating oils, heat-transfer liquids and coolants with temperature control and conditioning.
PRC
Specific process fluids
Solvents, cleaning products and chemically demanding fluids following documented compatibility and safety review.
Applications
Use cases, not a fixed catalogue.
Each bench is defined for the product and test conditions. These examples show the types of requirement we can assess.
01
Valves and check valves
Measure opening pressure, pressure drop, flow, internal leakage or cycling performance.
02
Hoses and pipework
Carry out proof tests, leak detection, pressure cycling and cleanliness checks.
03
Pumps and actuators
Characterise operation, pressure, flow, generated force and endurance behaviour.
04
Heat exchangers
Check tightness, pressure drop, circulation and behaviour at different temperatures.
05
Aerospace or industrial components
Reproduce a functional sequence using the actual fluid or a technically validated substitute.
06
Fluid subassemblies
Control several devices, verify safety functions, record measurements and issue a traceable result.
Our method
A clear and verifiable process.
- 01
Identify the fluid and constraints
Reference, SDS, viscosity, temperature, cleanliness, hazards and non-contamination requirements.
- 02
Define pressure and flow ranges
Nominal and extreme values, required accuracy, transients, pressure drops and ambient conditions.
- 03
Describe test scenarios
Manual or automatic sequences, ramps, dwell stages, cycles, acceptance criteria and fault stops.
- 04
Size the circuit and safety systems
Materials and seals, tanks, pumps, filtration, containment, cooling and protective systems.
- 05
Integrate sensors and acquisition
Pressure, flow, temperature, level or leakage measurement, then acquisition, supervision and logging.
- 06
Validate through factory testing
Set-up, safety checks, factory acceptance testing and delivery of the agreed results and documents.
