Merkel Omegat OMS-MR PR Merkel Omegat OMS-MR PR O-ring Pressure relief boring PTFE profile ring Injection moulding machines, mills, agricultural machinery, presses, earth moving equipment, large cylinders, industrial vehicles, cranes, control and regulation equipment, marine hydraulics. Material Fig. 1 Merkel Omegat OMS-MR PR Product description PTFE profile ring Material Code Colour PTFE bronze compound PTFE B602 Brown PTFE glass MoS 2 compound PTFE GM201 Grey PTFE carbon fibre compound PTFE C104 Dark grey Two-component Merkel seal set for sealing piston rods, consisting of one PTFE profile ring with integrated pressure-relief function and an elastomer ring as preload component. Patented product design (patent no.: DE 10117662 CI). O-ring Material Nitrile rubber Other combinations of materials are available on enquiry. Code NBR Product advantages Can be exchanged with operating environments of the Merkel Omegat OMS-MR Series. Increased operating reliability of sealing systems with demanding operating parameters (no continuously pressure build-up in gap area) Extended service life of sealing systems by long-term stability (reduced loading of the sealing system by minimised friction and wear). Application Primary seal in a sealing system - longer stroke (greater than 400 mm) High stroke speed when piston rod extends (greater than 0,5 m/s) High speed differences depending on the direction of movement (V out greater than 8xV in) Fast pressure drop in main area Large diameter (greater than 310 mm). Operating conditions Material PTFE B602/NBR PTFE GM201/NBR PTFE C104/NBR Temperature range in C Hydraulic oils HL, HLP 30 +100 30 +100 HFA fluids +5 +60 HFB fluids +5 +60 HFC fluids 30 +60 HFD fluids Water +5 +100 HETG (rapeseed oil) 30 +80 30 +80 HEES (synthetic ester) 30 +80 30 +80 HEPG (glycol) 30 +60 30 +60 Mineral greases 30 +100 30 +100 Pressure p in MPa 40 Running speed v in m/s 5 The specified values are maximum values and must not be applied simultaneously. Surface quality Surface roughness R a R max Sliding surface 0,05 0,3 µm 2,5 µm Groove base 1,6 µm 6,3 µm Groove flanks 3,0 µm 15,0 µm Percentage contact area M r >50% to max. 90% at cutting depth c = Rz/2 and reference line C ref = 0%.

Gap dimension The dimension D2 is determined under load with reference to the maximum permissible extrusion gap, the tolerance levels, the guide play and the compressive deflection of the guide. Technical Manual. The maximum permissible extrusion gap with onesided position of the piston rod is primarily determined by the maximum operating pressure and the temperature-dependent form stability of the sealing material. Profile Max. permissible gap dimension L Profile 16 MPa 26 MPa 32 MPa 40 MPa 4,2 5,35 0,5 0,4 0,3 6,3 7,55 0,55 0,45 0,35 0,3 8,1 10,25 0,6 0,5 0,4 0,4 8,1 12 0,7 0,6 0,55 0,5 9,5 13,65 0,75 0,65 0,6 0,55 8,1 12 0,7 0,6 0,55 0,5 9,5 13,65 0,75 0,65 0,6 0,55 At an operating temperature above 90 C and simultaneously applied operating pressure above 26 MPa we recommend the use of the material compounds PTFE B602 and PTFE C104. Mode of operation The Omegat OMS-MR PR has an integrated pressure-relief function. Once the gap pressure pz is greater than the pressure in the main area ph (e.g. caused by poor speed conditions during extension and retraction) the seal is reliably relieved. The sealing function of the Omegat OMS-MR PR is similar to the tried-and-trusted Omegat seals. Position in the operating environment pz < ph Position in the operating environment during pressure relief Gap area pz Main area ph Gap area pz Main area ph pz = pressure in the gap area; ph= pressure in the main area Fitting & installation Careful fitting is a prerequisite for the correct function of the seal.

The catalog details are based on the experience of many years of research in the development and production of seals in the Freudenberg Group and correspond to our current level of knowhow. The sealing action of many catalog products is, however, not only created by the component itself. In many cases depending on the specifi c application it depends signifi cantly on the other parameters, such as installation point, counter surface, pressure, operating temperature, media to be sealed, lubrication, effects of vibration and any ingress of dirt from outside. These and other unknown factors in practical use may noticeably infl uence the functioning of the seals. Against this background generalised statements on the function of the catalog products are not possible. Details in this catalog merely represent general and non-binding reference values which make no claim to be valid for every application. We therefore recommend you to always discuss specifi c applications with our consultancy service. In the event of very high and special loads, for example due to aggressive media, the seal should be selected in co-operation with us; trials to check the functional reliability are often indispensable.
