Causes of abrasion

Poor quality and contamination of the hydraulic medium will reduce the durability of your components.

Abrasion, dirt or obsolescence are the main causes for the regular replacement or necessary conversion of the hydraulic components. In addition, an incorrect viscosity of operating media influences the lubricating properties or operating temperatures.

  • Contamination of the hydraulic medium
  • Improper operating medium
  • High temperatures and leaks
  • Unsuitable ambient conditions
  • Obsolete operating media
  • Improper component selection and operating errors (excessive load changes, cavitation, overload, overpressure, ignoring protective mechanisms)
  • Lack of maintenance

Keeping the focus on your application

Whether high-quality ATEX components for explosion-proof areas with all necessary classifications, hydraulic components for high and medium pressure hydraulics, or special components for mobile hydraulics or stationary industrial hydraulics with all necessary approvals – as a supplier and hydraulics specialist, we always offer you a system-compatible solution.
