APPLICATIONS

Hydrau­lic and pneu­ma­tic app­li­ca­ti­ons in gene­ral mecha­ni­cal and plant engi­nee­ring

CHARACTERISTICS

  • Wiping/scraping effect in bores with line­ar or heli­cal moti­on 
  • Full dry run­ning pos­si­ble – low bre­a­ka­way tor­que 
  • Wide flu­id and tem­pe­ra­tu­re spec­trum
  • Except for small dia­me­ters, can be instal­led in non-split groo­ves 
  • Cus­to­mi­zed dimen­si­ons can be sup­plied for non-stan­dard housings 
  • Avail­ab­le in any dia­me­ter from 10 mm to 3,000 mm

TEMPERATURE RANGE

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

but depen­dent on the wiper/scraper and O‑ring mate­ri­al in each case.

MATERIALS

IDG wiper/scraper mate­ri­al

  • 91B (pneu­ma­tics)
  • 62A (water hydrau­lics)

O‑ring elas­to­mer

  • NBR
  • FKM (hig­her chemical/temperature resis­tan­ce)
  • EPDM (steam envi­ron­ments)

Wiper/scraper cross­sec­tions in alter­na­ti­ve ver­si­ons

The stan­dard ver­si­on is uni­ver­sal­ly usable, but in spe­cial cases the light ver­si­on can offer addi­tio­nal advan­ta­ges.
The light ver­si­on is sui­ta­ble for tight instal­la­ti­on con­di­ti­ons and is also easier to fit in non-split groo­ves.
This ver­si­on redu­ces the fric­tion. The low com­pres­si­on reser­ve with a nega­ti­ve effect on lar­ge tole­ran­ces must be con­si­de­red.
