APPLICATIONS

  • Developed for seal­ing of Kaplan blades 
  • Also suit­able for use on pivot pins 
  • Usable for water and oil hydraulics

CHARACTERISTICS

  • Radi­al adapt­ab­il­ity com­pensates for off­set and misalignment
  • Easy to handle due to robust construction 
  • For ret­ro­fits the seals can be adap­ted to exist­ing install­a­tion dimensions
  • Avail­able in any dia­met­er up to ca. 2,500 mm

TEMPERATURE RANGE

From -20 to +200 °C

Kaplan tur­bines are typ­ic­ally used for river power plants on calm waters. The blade angle run­ner blades (Kaplan blades) is adjustable. The pres­sure of the water flow, which is con­trolled by the guide vanes of the upstream wick­er gate, can then be effi­ciently con­ver­ted into energy.

The bid­irec­tion­al MANOY® sys­tem seal WP, type 444, in the form of a con­tinu­ous ring was developed to pro­tect the hydraul­ic adjust­ment device and pre­vent hydraul­ic flu­id leakage.

Type 449 is par­tic­u­larly use­ful for main­ten­ance work because rather than being con­tinu­ous in cir­cum­fer­ence, the seal is open and has a guide blade.
