APPLICATIONS

  • Rotary uni­ons 
  • Rotary actu­at­ors 
  • Rotary cyl­in­ders

CHARACTERISTICS

  • Sys­tem pres­sure activ­ated seal energization
  • Very long seal life due to high abra­sion resistance 
  • For use at low to medi­um pres­sure at low speed 
  • Does not stick to the mat­ing sur­face after pro­longed shutdown 
  • Avail­able for any dia­met­er between 6 mm and 1,000 mm

TEMPERATURE RANGE

From -40 to +200 °C

but depend­ent on the mater­i­al of the seal­ing lip and the O-ring of the sec­ond­ary seal in each case.
Ice crys­tal form­a­tion must be avoided.

MATERIALS

IDG seal­ing ring material

  • 36B
  • 40A

O-ring elast­omer

  • EPDM13
  • FKM13

Hygien­ic Design

Design of the hous­ing in the form of a groove should be avoided if pos­sible. If this is not feas­ible, good hous­ing and seal cleanab­il­ity must be guaranteed.

The hygien­ic design require­ments can be met by hav­ing a par­tic­u­larly large groove base radi­us and a split housing.

For WIP/WOP clean­ing it is import­ant to be able to remove and replace the seal without dam­aging it.

Giv­en a suit­able machine design, clean­ing in place is also possible.
