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.
