Espey WDKS-Eco

Features

  • Multi-part seal rings, radially cut
  • Split housing design
  • Very small operation gap - low leakage
  • Dry running
  • Self-adjusting seal rings
  • Seal rings bear radial shaft movements
  • Compensates axial shaft movements
  • No sealing components mounted on the shaft and hence no additional shaft vibrations
  • Seal rings running contact-free - sliding faces and machine consume no additional power

Advantages

  • Easy installation by split housing design (shaft removal not required)
  • Long-term operation time
  • Maintainability
  • Segmented seal rings for easy replacement
