Take care of your machines with a reliable and accurate diagnosis


The 5 important objectives of Maintenance Managers | Workshops | Parks
  1. See problems appear
  2. Be an active player before breakdowns
  3. Optimise the production of equipment
  4. Forecast and plan maintenance work
  5. Create more accurate budgets

Analysis of operating lubricants: This technique, which appears simple since it just consists in taking a small sample of oil, requires sophisticated analytical means and above all, the involvement of specialists to interpret the results of the analysis.

The relevance of the oil analysis mainly depends on how the sample is taken. In modern analytics, measurement units are extremely small: ppm (parts per million). The slightest impurity in the container containing the sample can skew the analysis.
A correct assessment of the sample is only possible if the sample was taken carefully.

The 7 functions of a lubricant

1 – Transmit energy

  • Pressure energy
  • Speed/flow energy

2 – Lubricate

  • All components which need to be lubricated: pumps, engines, actuators, seals, etc.

3 – Cool

  • Remove the heat created by mechanical work, rolling or released by the surrounding environment

4 – Protect

  • All components from corrosion and rust when stopped

5 – Maintain sealing

  • Thanks to an appropriate viscosity, the lubricant reduces leaks in pumps, engines and actuators

6 – Remove contaminants

  • Wear and imperfect sealing results in contamination. Oil transports these particles to the filters.

7 – Inform

  • About the operation of the installation (pressure, flow and temperature)
  • On the condition of the equipment and oil (through analysis)


The aim of the analysis of a lubricant

The aim is to detect the main anomalies to give the Maintenance Manager accurate information on the condition of the machine, and this by searching in the lubricant for:

  • All pollution phenomena
  • All contamination phenomena
  • All metals coming from wear
  • For engines: study of the combustion quality
  • In certain cases, and especially when change intervals are too long, the condition of the lubricant


The control and analysis are important to know the condition of a system and its hydraulic fluid.

Our laboratory and our high performance equipment will quickly diagnose your oils and fuels. Our in-house analysis department aims to help you make the right decisions in terms of monitoring and corrective actions, if required (decontamination, particulate filtration, removal of water or draining a tank, even the complete volume of the installation).

Since we are not affiliated with oil companies, our analysis are neutral and is the view of the hydraulic engineer working on the sample or the operator who must maintain the cleanliness of fluids, taking into account the context of the machine and the hydraulic/lubrication systems in question.

These analyses can be conducted on site, at a work site or in our laboratory. At the start of the intervention, they target the type of contaminant to be removed and therefore, the type of technology to be applied. During and at the end of the treatment, they will allow the achieved level of cleanliness to be validated.

A final report will allow you to identify the causes of the pollution, our practical recommendations will ensure you optimise your maintenance and production procedures.
