Features

New design and enhanced characteristics of WKA1100HP
  • Chamber seal (modular design - can be combined in any order)
  • New anti- rotation lock device
  • Light ring design with unchanged robustness
  • Very small operation gap - low leakage
  • Axial and radial limited space requirements
  • Dry running
  • Seal rings bear radial shaft movements
  • Seal rings running contact-free - sliding faces and machine consume no additional power
  • One-piece seal ring with titanium bandage
  • Two side balanced seal ring inside chamber for short-term backpressure operation
  • Seal ring axially spring-loaded – no contact to the shaft due to its own weight

Advantages

  • High reliability
  • Long-term operation time
  • Maintainability
  • Wartungsfreundlich
