Higher Reliability and Resistance because ofTargeted Pressure ReliefThe Merkel Omegat OMS-MRPR is a two part set of sealsconsisting of a PTFE profile ringand an elastomer ring as thepre-tensioning element. It isused as a primary seal withina sealing system.12 43 561 Pre-tensioning element2 Pressure-relief bore3 Anti-extrusion radius4 Profile ring5 Effective support of sealingedge6 Wedge-shaped sealMaterials AvailablePTFE-profile ring:PTFE-bronze compound PTFEB602 orPTFE-glass-MoS2-compoundPTFE M201O-Ring:Nitrile rubber 70 NBR B276Hardness: 70 Shore A orFluoro rubber 70 FKM K655Hardness: 70 Shore AThe Merkel Omegat OMS-MRPR has a defined pressure-relieffunction. As soon as the pressurein the intermediate spacepz becomes greater than thepressure in the main area pH(caused e.g. by disadvantageousspeed conditions whenmoving in and out), the seal isreliably relieved of pressure. Thesealing function of the MerkelOmegat OMS-MR PR correspondsto that of our tried andtested Merkel Omegat seals.Position in DesignSpace – Operationpz < pHIntermediate space pzMain area pHPosition in Design SpaceDuring Pressure Reliefpz > pHIntermediate space pzMain area pHpz = Pressure in intermediatespacepH = Pressure in main areaWith Merkel OmegatOMS-MR PR from Simrityou profit from numerousadvantages■ PTFE sealing element withpressure relief, thereforeno permanent build-up ofpressure is possible in theintermediate space■ Very high pressure resistance■ Good thermal conductivity■ Very good extrusionresistance■ High abrasion resistance■ Low friction■ Free of stick-slip■ Patented product design(Patent no.: DE10117662 CI)The primary rod sealMerkel OmegatOMS-MR PR from Simritstands for reliablesealing solutions in:■ Earth-moving equipment■ Industrial vehicles■ Agricultural machinery■ Lorry loading cranes■ Injection-moulding machines■ Control and regulatingequipment■ Marine hydraulics■ Presses■ Rolling mills3
