APPLICATIONS

  • Developed for seal­ing of guide vanes 
  • Also usable on Kaplan blades and pivot pins 
  • Suit­able for water and/or grease lubrication

CHARACTERISTICS

  • Reli­able func­tion­al­ity if there is oscil­la­tion and vibra­tion on the system
  • Anti-twist design for smooth oper­a­tion even dur­ing change of rotat­ing dir­ec­tion with vibration 
  • Avail­able in any dia­met­er up to ca. 2,000 mm 
  • For ret­ro­fits the seals can be adap­ted to exist­ing install­a­tion dimensions

TEMPERATURE RANGE

From -20 to +200 °C

The guide vanes con­trol the inflow of water in turbines.

These vanes run in slid­ing bear­ings. To give the bear­ings longer term pro­tec­tion from water infilt­ra­tion, the inner seal­ing MANOY® sys­tem seal WP, type 428, was developed for stand­ard specifications.

Type 487 with integ­ral scraper was designed for high spe­cific­a­tions due to abras­ive con­stitu­ents in the water and/or long inspec­tion inter­vals. The hous­ing for this seal must be open.

The pro­file dimen­sions of both ver­sions can be cus­tom­ized to adapt to exist­ing groove designs.
