Espey WKA1100HP

Features

  • Chamber seal (modular design - can be combined in any order), optional with housing and lid
  • Very small operation gap - low leakage
  • Dry running
  • 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
  • One-piece seal ring with titanium bandage
  • Both side balanced seal ring inside chamber for short-term backpressure operation
  • Seal ring axially spring-loaded – no swinging up at pressure-less machine operation

Advantages

  • High reliability
