Oils - everything flows smoothly

Liquids for power transmission, lubricants

Unnecessary losses due to corrosion and wear alone in Germany are estimated at 35 billion euros per year. We help to save materials and costs. Our consulting in this area goes far beyond the usual testing spectrum. Whether in mechanical engineering, power plant technology, steel industry, mining, or the food industry - tribology is becoming increasingly important for many industrial sectors.

Our experts conduct chemical, physical, and technological examinations and assessments of lubricants and hydraulic fluids. Additionally, we offer compatibility tests of fluids with standard elastomers or customer seals, as well as corrosion tests with different metallic materials.

TÜV NORD Test Seal

Your top-quality products are characterized by consistent quality, and to independently confirm this, we offer our exclusive testing and certification program. This program is aimed at manufacturers and distributors of tribological products such as oils, lubricants, and additives. If you regularly have your products checked for consistent product quality, we award the TÜV NORD Test Seal, which can then be used on the products.

Our offer for manufacturers and distributors:

  • Testing the physical properties of the products
  • Evaluation of consistent parameters within the tolerance limits of the testing program
  • Independent testing laboratory
  • Regular, recurring checks
  • Test mark with reach
  • Trust with end customers
  • Guarantee of longevity and extension of service life when used in machinery
  • Flexible design of the test framework according to the product's requirements

fire risk

The use of fire-resistant hydraulic fluids falls under this category. The testing and assessment of these material properties are standardized in Germany and Europe. Furthermore, there are international regulations that describe corresponding test procedures and the evaluation of the results. Below, various classification and testing standards for hydraulic fluids are described and explained.
