Espey WDMS500

Features

  • Multipart seal rings, overlapped mortized with gas-tight joints
  • Split housing design
  • Lowest possible operation gap - lowest leakage
  • Dry running
  • Self-adjusting seal rings
  • Seal rings bear radial shaft movemnts
  • Compensates axial shaft movements
  • No sealing components mounted on the shaft and hence no additional shaft vibrations
  • Cooling sealing area for high temperature applications not required

Advantages

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