n Introduction

Turcon®

Varilip®

PDR rotary shaft seals extend theboundaries imposed by elastomer radial shaft seals,utilizing advanced materials and design techniques toprovide optimum sealing performance for eachapplication. The outcome is a superior sealing solution,which retains a compact seal envelope.

Standard elastomeric rotary shaft seals have a limitedapplication range with respect to temperature, surfacespeed, media compatibility, pressure or a combination ofthese due to the inherent limitations of the variouselastomer grades. Furthermore they only have a limitedsuitability for applications with inadequate lubrication.

Turcon® Varilip® PDR rotary shaft seals are characterized inparticular by the low friction and their stick-slip-freerunning, reducing the temperature generation andpermitting higher peripheral speeds.

Turcon® has the characteristic of inherent memory,whereby a distorted Turcon® component will attempt torecover to the profile it had during the sintering cycle of itsmanufacturing process. This feature is used to provide thenecessary radial loading of the sealing lip onto the shaft,negating the requirement for the energizing springpresent in elastomeric seal designs.

n Description

Turcon®

Varilip®

PDR seals are constructed from only twoparts - a precision manufactured metal body and amechanically retained Turcon® sealing element. Unlikeseals with pressed metal cases, a gasket is not required toprovide sealing between the lip and casing. This is providedby the mechanical retention of the lip, improving both thechemical resistance and temperature range of the sealingsystem.

Figure 89 Turcon® Varilip® PDR seal

Where required, the Turcon® Varilip® PDR seal is available

with a hydrodynamic feature on the Turcon® sealing lip.This provides a positive displacement of the fluid as a resultof the shaft rotation to give improved sealing inapplications where the shaft only rotates in a singledirection. The feature also increases the flexibility of thelip, which allows a wider contact band between theTurcon® lip and the shaft and helps to reduce shaft loadand associated wear temperature.

The mechanical retention of the Turcon® provides a robustproduct which also el iminates the sometimesenvironmentally hazardous process of bonding theTurcon® to a metal or elastomer substrate.

Table LXI Seal configurations

Seal Description

Type A/Type 1 Type A - is a single lip seal suitable for use in standard industrial applications up to a pressure of 0.5 MPa (73psi) where an elastomer radial shaft seal would be unable to withstand the temperature, friction, medium orpoor lubrication. Allows sealing at surface speeds up to 90 m/s (17,721 ft/min) with sufficient cooling andlubrication of the sealing lip.

Type B/Type 3 Type B - is the preferred choice for applications in which a high seal integrity is demanded or wherecontaminated media are to be sealed. This type offers a back-up sealing lip to provide secondary sealing.Pressure limit is 0.5 MPa (73 psi).

Type C/Type 4 Type C - can be used for applications involving higher pressures for which a simple elastomer radial shaft sealcan no longer be considered. Due to reinforcement of the sealing lip, pressures up to 1 MPa (145 psi) arepossible, e.g. as pump, shaft or rotor seals.

Type D/Type 5 Type D - can be subjected to pressure from both sides. Pressure differential of up to 0.5 MPa (73 psi) ispermissible. The separation of two different media using a single seal is possible. The second lip can also takeon the function of a wiper or dust lip.

Type G/Type 6 Type G - is similar to Type D but has a non-contacting environmental sealing element rather than a full lay-down lip. This provides effective sealing against the ingress of dust and dirt into the system while alsoensuring torque and resulting power consumption are kept to a minimum.

n Materials

Sealing lip

An important factor for the proper function of rotary shaftseals is the material used for the sealing lip. For this reason,Trelleborg Sealing Solutions has developed a range ofspecially modified materials on the basis of the provenTurcon® materials. Particular importance is attached to theoptimization of friction and wear properties, whileproviding excellent sealing performance, even at highperipheral speeds.

Table LXII gives the materials available for use in Turcon®

Pressure

Turcon® Varilip® PDR Types A, B, D and G are suitable forpressures up to 0.5 Mpa (73 psi). Type C provides a doublesealing lip design for pressures up tp 1 Mpa (145 psi).

Pressure heavily influences the contact force between theTurcon® lip and the shaft and consequently the heatgeneration. This must be taken into consideration whenselecting the appropriate seal type.

Turcon® Varilip® PDR seals can remain leak tight whenexposed to pressurization during static shaft conditions.

Fluid resistance

Turcon® consists of fully substituted carbon-carbon chainsand the resulting carbon-fluorine bonds are among thestrongest known in organic chemistry. The outstanding

physical and chemical properties of Turcon

®

can beattributed to these strong bonds.

Turcon® Varilip® PDR seals are resistant to mineral acids,bases, common organic fluids and solvents. They are alsounaffected by oxidation, ultraviolet radiation or ozone,making them ideally suited for use in the chemical industryand applications requiring exposure to the atmosphere.

A particular benefit of Turcon® Varilip® PDR seals is aresistance to oil additives and biofuels, which have anadverse effect on many elastomers. Using Turcon® shaftseals allows the increased use of additives and a longer oilservice life.

Many Turcon® materials have been successfully tested in 20percent Fluorine gas at temperatures in excess of 250°C(482°F).

Lubrication starvation

Turcon® Varilip® PDR shaft seals have the capability to runwithout lubrication for longer periods of time comparedwith elastomer shaft seals without adversely affecting theirultimate life. This not only allows them to be used inapplications where the lubrication may be intermittent as aresult of start up or other operating factors, but also allowstheir use as effective dirt, dust and powder seals.

Note: Higher speeds and pressure capabilities can be

achieved through the use of custom designs. Pleaseconsult your local Trelleborg Sealing Solutions marktingcompany.

Heat generation considerations

All Turcon® Varilip® PDR seals are designed to contact theshaft surface during operation. The contact force betweenthe sealing lip and the shaft will depend on the seal designused and the application details, but in all cases atemperature increase due to the presence of the seal canbe expected. Where this increase is likely to be significant,consideration should be given to methods of reducing thelevel of generated heat. This can be achieved throughincreases in localized cooling, improved lubrication andefficient heat transfer and dissipation mechanisms.

Shaft wear

Turcon® Varilip® PDR seals are designed to contact the shaftsurface during operation and a seal contact band will beevident in the majority of applications. With correct sealspecification and operating conditions, shaft wear shouldbe limited to a light polishing, but factors such as overpressure, contamination, eccentricity or insufficient shafthardness can result in more significant wear.

As part of the system design, consideration should be givento the level of shaft wear permissible within a set operatingperiod, and therefore the benefits of measures intended toreduce the rate of wear, such as shaft coatings, can beanalyzed in relation to their additional cost.

n Design Guidelines

Housing

Turcon® Varilip® PDR seals are designed to meet global

standards, including ISO 6194/1 and ISO 16589. (See tablesLXX and LXXI).

Turcon® Varilip® PDR seals require an interference fit withthe housing bore to provide both adequate sealing of thisinterface and to ensure that the seal remains in place whensubjected to pressure, axial movement and induced torsionproduced by the relative rotary motion of shaft to housingbore. The bore should be machined with an H8 diametrictolerance as reproduced in table LXVI below. System designshould also ensure that Turcon® Varilip® PDR seals are notpushed into bores that may have been previously scored bythe assembly of another component, (such as a bearing),selecting a larger seal outer diameter if necessary.

For Turcon® Varilip® PDR seals the bore should have asurface finish of 0.8µm (32 µin) Ra maximum. In caseswhere the housing bore is split resulting in an axial jointcrossing the seal outer diameter, and in cases wheremeeting these surface finish requirements is not possible,it is recommended that a proprietary sealant or adhesive isused.

Alternatively a custom solution can be prepared employinga rubber covering or O—Ring for OD sealing.

A shaft hardness in excess of 55 HRc is generallyrecommended for Turcon® Varilip® PDR, although lowervalues are permissible depending on the pressure, speedand sealing lip material used (refer to materials section).

Titanium shafts should be avoided unless nitrided. Shaftswith good chrome, nickel or zinc plating, properly finished,are acceptable. Certain ceramic coatings can also be used,although some grades have been proven to result in anaggressive wear of the sealing lip due to their openstructure. In certain applications it may not be possible to

provide a shaft with the necessary hardness, surface finishand corrosion resistance. Fitting a wear sleeve onto theshaft can solve this problem by providing the local hardnessand surface requirement without affecting the main shaft.If wear should occur, only the sleeve need then bereplaced. The surface finish of the sleeve should be asoutlined above and consideration should be given toadequate heat dissipation and effective sealing of theinterface between the wear sleeve and the shaft.

n Installation Requirements

When installing Turcon® Varilip® PDR seals, carefulhandling is important in order to avoid damaging thesealing lip. If the seal is installed from the back, radii orlead-in chamfers must be machined on the end of theshaft. This must also be free from burrs, sharp corners orrough machining marks, as shown in Figure 102.

When installing the seal with the lip against the shaft end,a lead-in chamfer is required whose smallest diameter issmaller than the unstressed diameter of the sealing lip asshown Figure 103. Table LXVIV shows guide values for this.

It is recommended that as shallow an angle as practical beadopted within the range given.

Fitting should be performed in a swift movement to limitthe time that the lip is formed above shaft size, therefore

reducing lip recovery needed.

n Packaging

Single and low quantities of Turcon® Varilip® PDR seals willbe supplied in a blister pack with an individual transportmandrel. This mandrel will pre-form the element to aboveits free diameter, but below the intended shaft diameter.This assists in ease of installation, while also ensuring theelement is not over-formed or damaged in transit.

Larger quantities of Turcon® Varilip® PDR seals will be

supplied in a tube-and-end cap configuration.

n Storage

Turcon® Varilip® PDR seals do not require any specialstorage conditions, unlike elastomer seals which must bekept away from sunlight and elevated temperatures toavoid rubber degradations.

Turcon® Varilip® PDR seals are not subject to shelf life.




8/12/2019 PDR Seals


n Fitting Instructions

Investigation of premature failures has shown that asignificant proportion are a result of inappropriateinstallation techniques. However, by observing thefollowing guidelines, such failures can be avoided:

- Assembly sleeves and fitting tools should be regularlychecked for signs of damage.

- When supplied on mandrels the seals should not beremoved from the mandrel until immediately prior tofitting. Seals supplied on cardboard mandrels should beremoved in the direction such that the spiral paperoverlay of the mandrel is not lifted.

- Turcon® Varilip® PDR seals should be assembled on theshaft in an non-lubricated (dry) condition to avoidcontamination of the hydrodynamic feature (if present).

- Care should be taken not to damage the outer diametersurface of the seal.

- Seals should be pressed squarely into the housing withthe pressing-in force applied as close as possible to theoutside diameter of the seal.

- If the seal contains a hydrodynamic feature on thesealing lip, ensure that it is correctly oriented in relationto the shaft’s direction of rotation.

- Normal practice is to install the seal with the lip facingthe medium to be sealed (the seal is reversed only whenit becomes more important to exclude a medium than toretain it).

- Proprietary sealants or adhesives may be used forimproved sealing of the outer diameter in criticalapplications or for seal retention purposes.

n Installation Recommendations

The following diagrams show installationrecommendations in respect to seal retention underpressure conditions.

Post installation recommendations:

If painting, be sure to mask the seal. Avoid getting paint onthe lip or the shaft where the lip rides. Also, mask any ventsor drain holes so they will not become clogged. Be sure toremove masks before operating unit.

If paint is to be baked, or the mechanism is otherwisesubjected to heat, seals should not be heated totemperatures higher than their materials can tolerate.

In cleaning or testing, do not subject seals to any fluids orpressures other than those for which the seals have beenspecified.

Extraction features such as tapped holes, internal threadsor simple grooves can be included in custom PDR designs.
