APPLICATIONS

  • High pres­su­res at rela­tively low speed 
  • For fluids over a wide vis­co­si­ty ran­ge and for gases 
  • Rota­ry uni­ons at high pres­su­re
  • Robot axes 
  • Pipe joints
  • Injec­tion units
  • Rota­ry actua­tors
  • Rota­ry lift cylin­ders
  • Val­ve spind­les
  • Swi­vels

CHARACTERISTICS

  • Pres­su­re-activa­ted seal ener­gi­za­ti­on 
  • Clam­ping of the flan­ge in the housing pre­vents unwan­ted rela­ti­ve moti­on
  • Ide­al for slow rota­ry, oscil­la­ting and heli­cal moti­on 
  • Dry run­ning pos­si­ble 
  • Low coef­fi­ci­ent of fric­tion
  • Non-sen­si­ti­ve to pres­su­re peaks 
  • No chat­ter (stick-slip) at low speed 
  • Does not stick to the mating sur­face after pro­lon­ged shut­down 
  • Avail­ab­le for any dia­me­ter up to 2000 mm

TEMPERATURE RANGE

From ‑54 to +200 °C (tem­pora­ri­ly +260 °C)

but depen­dent on the mate­ri­al of the seal and the O‑ring in each case.

MATERIALS

IDG seal mate­ri­al

  • 82B (water hydrau­lics)
  • 32B (pneu­ma­tics)
  • 36B

O‑ring elas­to­mer

  • FKM

Spe­cial mate­ri­als are used at low tem­pe­ra­tures

PV limits

The dia­grams give PV limits which should be con­si­de­red as recom­men­da­ti­ons.

Note:
For dia­me­ters S < 50 mm, the ope­ra­ting para­me­ters must be fur­ther restric­ted due to poor heat dis­si­pa­ti­on.

Prac­ti­cal preli­mi­na­ry tests are necessa­ry near the limit cur­ves and also for tem­pe­ra­tures and fluids dif­fe­rent from the ones used here.
