APPLICATIONS

  • Deve­lo­ped for use with ser­vo motors
  • Uni­ver­sal­ly usable for water and oil hydrau­lics

CHARACTERISTICS

  • Sta­ble scra­ping effect and high abra­si­on resis­tan­ce give opti­mum ope­ra­tio­nal relia­bi­li­ty if the­re is a high abra­si­ve par­ti­cle con­tent and risk of cavi­ta­ti­on 
  • Pres­su­re-relie­ved scra­per lip mini­mi­zes the fric­tio­n­al force to gua­ran­tee good respon­se cha­rac­te­ris­tics
  • Low wear for very long ser­vice inter­vals
  • For retro­fits the seals can be adap­ted to exis­ting instal­la­ti­on dimen­si­ons 
  • Avail­ab­le in any dia­me­ter up to ca. 2,500 mm

TEMPERATURE RANGE

From ‑20 to +200 °C

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

MATERIALS

IDG stan­dard sealing ring mate­ri­al

  • A12 for the casing and scra­per ring
  • 57A for the sealing ring

O‑ring elas­to­mer

  • NBR

Ser­vo motors in hydro­power plants nor­mal­ly ope­ra­te water hydrau­li­cal­ly. The­se ser­vo motors per­form the func­tions of ope­ning, clo­sing and con­trol of shut-off and regu­la­ting devices and must be able to main­tain the set­ting posi­ti­on at any pre­vai­ling pres­su­re.
