APPLICATIONS

This type has not­ches becau­se of its low height and for a sen­si­ti­ve respon­se. This gives ade­qua­te cleana­bi­li­ty.

CHARACTERISTICS

  • Low brea­k­out force — even after long shut­down 
  • Long life due to high abra­si­on resis­tan­ce 
  • Dry run­ning pos­si­ble 
  • Sym­metri­cal design for instal­la­ti­on inde­pen­dent of pres­su­re direc­tion 
  • Free choice of dia­me­ter bet­ween 8 and 200 mm

TEMPERATURE RANGE

From ‑40 to +200 °C

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

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, avoi­ding not­ches and having 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.
