Espey WD500

Features

  • Multi-part seal rings, overlapped mortised with gas tight Joints (adjusting)
  • Split housing design
  • Lowest possible operation gap - lowest leakage
  • Dry-running
  • Self-adjusting seal rings
  • Seal rings bear radial shaft movements
  • Compensates axial shaft movements
  • Short axial installation length
  • No sealing components mounted on the shaft and hence no additional shaft vibrations

Advantages

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

[700 °C (1,292 °F) for blast furnaces],
-120 °C ... +150 °C (-184 °F … +302 °F) for PTFE compound
Sliding velocity:
vg = max. 40 m/s (131 ft/s)
Radial play: ± 2.5 … 5.0 mm (± 0.1" … 0.2")
Axial movement: theoretically unlimited
Recommended wear guard: >58 HRC
