APPLICATIONS

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

CHARACTERISTICS

  • Small base cross-sec­tions only cause slight com­pon­ent stress
  • Avail­able in any dia­met­er up to ca. 2,800 mm 
  • Com­pensates for eccentricity 
  • For ret­ro­fits the seals can be adap­ted to exist­ing install­a­tion dimensions
  • Anti-twist design (types 451, 456) pre­vents unwanted rel­at­ive seal motion and there­fore pre­ma­ture failure

TEMPERATURE RANGE

From -20 to +200 °C

Pivot pins are found on shut-off devices such as spher­ic­al valves, but­ter­fly valves, hol­low jet valves and plun­ger valves. These valves are gen­er­ally used for open­ing and clos­ing and occa­sion­ally to con­trol the flow rates by oscil­lat­ing movement.

The grease-lub­ric­ated slid­ing bear­ing is pro­tec­ted against water infilt­ra­tion by a seal on the inside. The seal also pre­vents the grease leak­ing into the inside to pre­vent water con­tam­in­a­tion. The MANOY® sys­tem seal WP, type 418, was developed for this application.

To pre­vent leak­age of grease from greased bear­ings, the uni­direc­tion­al MANOY® sys­tem seal WP, type 456, is also installed.
