Hydraulic fluids transmit forces, lubricate the moving parts of the device, cool, protect against corrosion and ensure that any vibrations are damped and impurities are removed. But in their work, these all-rounders have to meet ever greater challenges, such as higher pressures and rising operating temperatures.

Our seminar provides you with the tools you need to ensure the economical and reliable operation of your hydraulic systems in the long term. The seminar will focus on the correct selection of the optimum hydraulic fluid, cost reduction through better filtration, oil maintenance and extending oil change intervals, early detection of wear and faults, clarification of the causes of damage, the benefits of oil analysis for proactive maintenance and warning values for assessing machine damage and oil condition.

Target Group

  • Skilled employees and executives working in the field of maintenance
  • Engineers, foremen, fitters and service technicians from component and system manufacturers and their service partners
  • Distribution engineers and sales staff of lubricant producers and their resellers
  • Technical purchasers for lubricants and operating fluids
  • Application engineers working in mobile labs as well as for on-site condition monitoring and fluid management
  • Appraisors and surveyors for damage analysis and machine malfunction
  • Technically interested employees who want to extend their knowledge in the areas lubrication techniques and tribology

Aims

  • Correct selection of the optimum hydraulic fluid for economical and reliable operation of your system
  • Extension of oil changing intervals
  • Cost reduction through better filtration and oil care
  • Early recognition of unusual wear and failures
  • Investigation of causes of faliure after breakdowns
  • Extraction of meaningful oil samples
  • Oil analysis in pro-active maintenance
  • Interpretation of lab reports
  • Warning values for evaluation of machine damages and oil condition
