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.
