The data indicated in our catalogue are based on experimental values concerning

fabrication, bench performance and application of the sealing elements. In view of the

large number of parameters and boundary conditions, the generally valid application

limits can vary greatly so that the suitability for a particular application must be confir-

med by practical tests in the user’s works. No guarantee or liability can be assumed

for the validity of our recommendation in individual cases.

HECKER GSM PASTE M No. 1049A mineral oil-based lubricant with an additive of molybdenum disulfide which has been proven in practice over many

years. It can be well recommended for the application as installation and starting auxiliary for our GSM hydraulic and

pneumatic seals.d Einlaufhilfe für unsere GSM-Hydraulik- und Pneumatikdichtungen

HECKER GRAFIT PASTE K No. 1048Manhole, flange and screw lubricant. Avoids the burning together of flange seals and thus enables a quick and easy

loosening of worn seals. Prevents seizing of screws and nuts. This paste can also be recommended as lubricant for

rubber/fabric seals. Available in cans of 1 kg or in buckets of 15 kg.

CONTENTS AND INTRODUCTIONThe choice of seals for the hydraulic and pneumatic systems results from the consideration of a series of factors which

on a simplified basis can be devided into three main groups.

1. CONSTRUCTION DETAILSHere is to be considered, among others, the size and arrangement of the installation dimensions.

2. OPERATING CONDITIONSrespective seals are to be used. Here is to be considered: The comprehensive stress, the type of operating medium, the expec-

ted temperatures, running speed etc.

3. BUSINESS CONSIDERATIONSThese include the cost situation, questions concerning dates, that ist, the availability, also in the future, as well as the guarantee

of constant high quality for materials and performance.

Many of these factors mentioned above could contradict one another; also in many cases, the optimum solution can only be

found through a compromise. Therefore, the enormous choice of types and materials of the seals in this catalogue must be seen

from this perspective. The following tables contain profiles which have proven to be reliable in practice and thus represent our

standard program. We have included the ratings, installation notes and examples of application of every type of seal in order to

aid the design engineer in the right choice. For problem cases, the many years of experience which our technical consultation

service has, should be made use of.

APPLICATIONGSM-U-Rings UG can be used in hydraulic and pneu-matic systems on the basis of its symmetrical profile ascylinder or rod-seal.In addition, they proved themselves at dosage and fil-ling plants and rotating and pivoting cylinders. Undermost circumstances they should not be used whereimpeded business-conditions like pressure-pushes,vibrations, etc., are to expect.

WS 858: a NBR-material with approximately 86 ShA

WS 900: a Polyurethane-material with approximately 94

ShA

WS 071, 072: NBR-fabric materials, that differ in the

fabric-structure. These materials are delivered stan-

dardly graphitated.

A particular tool is required for each of these three

material-types.

UG1-Rings can be manufactured on customer-wish in

each material. If the following tables show no suitable

tool for the relevant measurements please ask us.

However, it must be taken into account that different

rubber-kinds can differ in the production-sizes especial-

ly when using the same tool for different materials.

CLEARANCE BEHIND THE SEALToo much clearance behind the seal leads to a prema-

ture failure oft he seal. The admissible clearance

behind the seal is calculated as follows:

WS 858 Badm= 0,3 – 0,001p

(for p up to 160 bar )

WS 900

and WS 072 Badm = 0,4 – 0,008p

(for p up to 400 bar)

If „badm“ is exceeded, the additional installation of back-

up rings of suitable plastic materials (PTFE, POM) must

be provided behind the seal.

c) Support by means of O-rings

It offers herself as alternative for the use-cases where

no defined support by means of o-rings stands by the

disposal, for which is striven mode of action of the

same, however. Also here, the suitable O-Ring-dimen-

sions must be determi-

ned by us.

Our technical service

department informs

and advises you on:

• Further dimensions available

• Further materials please refer to the general

table „Materials“

• Installation dimensions

• Extreme conditions

Tell us about your sealing problems, we will develop a

solution to meet your requirements.

SUPPORTFor UG 1-Rings, the addi-

tional installation of sup-

porting elements is recom-

mended

a) The metallic support ring: Has to made by the

customer. The sketch informs about the dimensions of

the parts.

b) The profiled rubber support ring: In contrast to

the metallic support element this support of observance

of the mounting-measurement .L" a (see table of dimen-

sions) causes an additional radial pressure on the lips,

that has an effect positively particularly with fabric-

seals, since these parts show less elastic behavior as

a pure Elastomer-sealing. Get along only a restricted

number of tools for defined

support rings is on disposal.

In many cases the use of a

cutted profile-string is possi-

ble. It must be checked by

our technical department.

MOUNTING AREA AND INSTALLATIONUNI-Rings are mounted without a seperate supportring. UNI1- and UNI3-Rings are more flexible and canbe mounted also in forehead closed mounting rooms. This kind of mounting is not possible in every mounting area, every material and every dimension of the ring.

CLEARANCE BEHIND THE SEALToo much clearance behind the seal leads to a premature failure of the seal. The admissable clearancebehind the seal is calculated as follows:WS 858:

bzul= 0,3-0,001p (pmax: 160 bar)

and for the other materials: 0,4-0,0008p (pmax: 400 bar)

APPLICATION• bottom-ram press

• High-pressure-plunger-pumps

• Steam-hammers

For these applications it is possible to use

single rings or sets of rings. Sets of rings are

recommended particularly in the cases, where

open rings must be used. The number of the

elements combined to the sets follows the

respective operating-conditions on that occa-

sion and in the case of doubt our technical

advice should be asked.

In addition, our cotton and Aramide fabrics

can be equipped also with other impregna-

vered with a surface in graphite. Further

materials see in chapter “materials”.

MOUNTING AREA AND INSTALLATION2-Lip-rings are delivered normally as closed

rings. With demand (badly accessible sealing-

areas), however also the delivery of open

rings with diagonally cut seal-ends is possi-

ble.

Open UNI 2-seals, immediately whether cut

out from the next bigger measurement or

manufactured from so-called length-tools, can

be used only set by set. The cutting of these

rings delivered with excess takes place the

best like follows.

a) Decide the correct scope-length through

putting on the sealing-ring about the Plunger.

b) The push-places of the cutted ring some-

thing must be a bit larger at good installation at

the Plunger in order to cause a small pressure in

scope-direction after the mounting in the stuffing-

box-area.

c = 0,1 x H

c) The push-places of the individual set-elements

are to be moved from ring to ring by approxima-

tely 120°. It is

recommended to

begin at the

exactly matched

push-places with

the montage of

open sealing-

rings in the stuf-

fing-box-room.

d) Difficult and heaviest business-conditions,

like for example high

press and speeds,

possibly make the

mounting of two

UNI2-rings necessa-

ry, as is represented

in following picture.

TOOLS FOR INSTALLATIONIn order to protect the sensitive lips with the

montage, suitable montage-helps and insertion

chamfers are to be intended.

ADJUSTING OF THE SEALING PRESSUREBefore the first operating use, the stuffing-box-

room can be attracted only easily. Only after

some lifting, insufficient sealing-effect can per-

haps be improved by well-measured after-spans.

In any case the span of the room must be cho-

sen in a way that an axial fixation of the sealing

set in the stuffing-box-room is guaranteed.

systems. For use-cases, where pressure-loose work-

phases frequently occur, the use of our MA3 and MA4

with feather-backed tension of the lip.is recommended.

SEAL PROPERTIESAll U-shaped-seals MA1-4 are equipped with relatively

long sealing-lips and flat shaped flange-looking sea-

ling-grunds, that show central-drillings with most mea-

surements. Partially, considerable differences are in

the relationship of pre-tension, lips and ground-

strength, centralisation e.g.given and declares itself

from the difference of the in each case first need.

The lips of our types MA3 and MA4 find out an additio-

nal pressure through interior-lying pressure-feathers at

the cylinder-wall.

The sealing-types MA2 and MA4 are approximately

looking round at the lip-back, MA1 and MA3 at this

place have a twisty transition to the ground.

MATERIALSThe MA-seals are delivered normally in the following

standard materials:

WS 858: a NBR- material with approx. 86 ShA

WS 900: a polyurethane-material with approx. 94 ShA

WS 071; 072: NBR-cotton-fabric materials which differ

in the structure of the fabric. Standard is a surface with

graphite (not possible for MA3 and MA4)

Further materials on inquiry.

The feathers for MA3 and MA4 are in standard-imple-

mentation out of unalloyed feather-steel-wire. These

can also be delivered in material 1.4310.

INSTALLATION AREA AND MOUNTINGMA-seals (with central-drilling) are installed into open

mounting-areas in principle, i.e. the necessary sealing-

compression at the flange-ground must take place by

means of a stretchable stationary-ring. A border for

pressing through attack should be intended. For the

seals MA2 and MA4, the metallic surface of the piston

must show the same radius as at the outer diameter

how it is to be found for the corresponding seal under

the table-measurement "R." This recommendation is

applicable to all R bigger than 3 mm.

CLEARANCE BEHIND THE SEALThe maximum clearance (b) behind the seal is:

WS 858 bzul = 0,2 mm

WS 900, 071 and 072: bzul = 0,3 mm

TOOLS FOR INSTALLATIONLook for useful installation tools and the right insertion

chamfer (C=0,3H) that you don’t damage the thin edges of

the lips.

ST CAP SEAL, ROD SEAL

APPLICATIONCap-seals ST are suitable as rod-seals for

walking movements into hydraulic and pneu-

matic systems. They proved themselves as

radial-sealing-elements, where slow trick, and

swing-movements from interior pressure-bur-

den take place, e.g. in mixer shafts - put - and

rule-elements in the turbine-construction and

at spindles für armatures. For use-cases,

where pressure-loose work-phases frequently

occur, recommends the use of our ST3 and

ST4 with feather-backed pre-tension of the

lips.

SEALING SPECIFICATIONSAll cap-seals ST1-4 have relatively long sea-

ling lips and even flange-grounds.

From dimension to dimension, partially con-

siderable differences are given in the rela-

tionship of pre-tension, lips and ground-

strength, that let itself explain mainly from the

difference of the in each case first need.

The lips of the sealings ST3 and ST4 beco-

mes an additonal pressing by a circular pull-

spring. The cap seal types ST2 and ST4 are

round on the back of the lip whereas the

types ST1 and ST3 have an angled passage

to the ground.

MATERIALSUGA1, 3 and 5 rings are delivered in the follo-

ted cotton-fabric material with a different

structure just as an attached vulcanized rub-

ber-part out of NBR.

Delivery is also possible in material

combinations with FPM and aramide.

Standard are rings with graphite on the surfa-

ce. UGA2 and 4 Rings are delivered - if orde-

red not differently - in our NBR-material WS

858 with 86 ShA. Further materials see chap-

ter “materials”.

CHARACTERISTICSUGA–Rings are compact packings. The pre-

tension comes through the distortion of a

massive elastomer-block. This block causes a

high sealing pressure for a long time also in

low pressure areas or in areas with no pres-

sure.

In contrast to the profiles UGA2 and UGA4,

which consist only of rubber, the types UGA1,

3 and 5 have an additional onvulcanized

fabric part. This increases the distortion-stabi-

lity, reduces the inclination to the extrusion in

the split and improves - particularly in the higher

pressure-areas - the rubbing behaviour of the

seal through lubricant-storage in the fabric-

surface-structure.

CLEARANCE BEHIND THE SEALToo much clearance

behind the seal leads to a

premature outage of the

sealing properties. The admissible clearance

behind the seal b is calculated as follows:

UK V-PACKING, ROD & CYLINDER SEAL

GSM-UK U-ring-sets are sturdy multisectional sealing-

elements. They consist of adapter rings and several UK-

Rings. The UK-Rings are conical at the back. If you put

several UK-Ringe to a set together, they touch itself only

at the powerful back of the profile (back-radius). The sea-

ling lips even lie exposed on that occasion and are spre-

ad by oncoming pressure.Therefore an axial after-tension

is not possible.

If no tools for supports and thrust-ring are presented in

our measurement-table, these must be manufactured out

of metal of the customer.

APPLICATIONUK-sets are suitable for the insulation of plunger pumps,

piston-rods and pistons with high demand. The lying

exposed lips guarantee a comparatively low friction

opposite after-ductile set-types here, for example what

with free-fall-plungers at sub-piston-presses of advantage

is. Also the use proved itself at high-speed plunger

pumps, that work with very high pressing and pure water

without lubricant-addition as pressure-medium. If good

insulation is necessary in the low-pressure-area, our

after-ductile NK-sets should be preferred.

UD1 U-RING SET, ROD SEAL

GSM-U-Ring sealing sets UD1 are multisectional sealing-ele-

ments in robust implementation. They consist from ever one

support-ring and a thrust-ring and several UD1-U-rings, whose

special profile-formation a radial spreading of the lips causes

with oncoming pressure and axial glasses-tightening. This

after-tightening allows a cost-lowering extension of the sea-

lings stand-time beside the attitude of a optimal sealing-effect.

UD1-sets, for which are tools according to following table exi-

sting, can be delivered as open or closed rings. Inter-sizes, for

which no matching tools are available, however are available

only in open implementation. Theyare cut out from the next-

bigger, unending dimensions.

APPLICATIONUD1-U-ring-sealing sets are suitable because of their sturdi-

ness to the insulation at plungers and piston-rods in the

heavy-hydraulics, how for example at cutting-presses, rope-

presses etc.. Their use as ros seals restricts itself to special

cases. However, their application is recommended everywhere

there, where are through exceptional operating-conditions, like

lateral pushes or strong disruptions , high requests for the

sealing-elements. The friction-strengths are with UD1-sealing

sets somewhat more highly in general. They are less been

suitable for this reason in cases where only restricted friction-

strengths are (for example plungers, that should fall back into

their exit-situation through their net weight) allowable.

The right cutting at the mounting of open

about the plunger. The stick parts of this

of ready cutted rings must be a bit lon-

ger at good installation around the

Plunger in order to cause a small jolt of

the ring in scope-direction after the

ADJUSTMENT OF THE SEALING PRESSUREBefore the first installation, the stuffing-box-glass can be attracted only easily. Only after some

lifts of the plunger, insufficient sealing

effect can perhaps be improved by well-measured after-spans.

With operating-media with elevated swelling-effect on the sealing-material, the most favorable

NOI 1 LIP-SEAL-SET, ROD SEAL

NOI1-sets are been suitable as sealing-element

for rods and plungers particularly there where

the maximum pressure becomes effective with

long lifting and relatively high lifting-speed only

over one relatively short work-area. The long lips

favor a comparatively good friction-behaviour on

this occasion and are able to equalize certain

leadership-imprecisions through their flexibility.

The use of NOI1-sets spreads from the spindle-

insulation in the armature-industry over the use

as press-insulation in the hydraulics until to the

approved sealing-elements at smithy-presses

and steam-hammers.

rings in WS 054 (CR-impregnated aramide

fabric). When dimensions for the rubber-tools

exist, we manufacture support rings and pressu-

re-rings in our NBR-standard-material WS 858

with approximately 86 Shore A. For some dimen-

sions we can produce rings in our especially

wear-solid hard-fabric-quality WS 090.

If special operating-conditions make it necessary,

like for example higher temperatures, heavy-

inflammable liquids) NOI-sets can be delivered

also in for this suitable materials. (for further

materials please refer to the general table for

materials)

CLEARANCE BEHIND THE SEALWith application of fabric-pressure-rings, the

allowable clearance behind the seal „bzul“ is

calculated as follows:



bzul = 0,5 – 0,0005p (for p up to 400 bar)

SUPPORTIf the adapter rings must be manufactured of

metal, following drawing of the measurement-

establishing serves:metal adapter ring sealing ring NOI1 metal adapter ring

round the edges

a = H - h + 0,3S

R = 0,44S

C = 0,25S

e = 0,6S S = (D-d)/2

In difference from the usual set-construction a

series of proved set-combinations is used in

the practice. Instead of a metallic adapter ring

an exactly dimensioned O-Ring can cause

additional pressure of the neighboring NOI1-

lips one and can improve the sealing-function

with it in the low-pressure-area.adapter ring (o-ring)

The combination of NOI1-sealing rings with

special soft-stuffing-box-rings causes an

essential reduction of the friction through their

high lubricant-share.

soft stuffing box ring

An adapter ring installed in the set can serve the

leakage-drainage, bring additional lubricants

against the seal or with armatures and agitator

gearings of suitable locking medias.

CORRECT CUTTING FOR INSTALLATIONOF OPEN RINGS AND INSTALLATIONINSTRUCTIONSOpen NOI1-rings can cut out been delivered

from so-called length-tools and cutted out from

bigger tools.. The cutting should be done like fol-

lows: the exact seal-length is determined by put-

ting on around the plunger. The push-places of

this ready cutted rings must be a bit longer at

good installation at the plunger in order to cause

an easy accumulation in scope-direction after the

mounting in the stuffing-box-room. C = 01 * H

The push-places of the individual set-ele-

ments are to be moved from ring to ring by

approximately 120°.

When mounting the sealing-rings in the stuf-

fing-box-room, it is advisable to begin with the

exactly matched push-places.

TOOLS FOR INSTALLATIONTo save the thin lips at the installation use

correct mounting tools and insertion cham-

fers.

rounded edges insertion chamfers

rounded edges rounded edges

ADJUSTMENT OF THE SEALING PRESSUREBefore the first use, the stuffing-box-glass can

be attracted only easily. Only after some lifts

of the plunger, insufficient sealing-effect can

perhaps be improved by well-measured after-

spans.

With operating-media with elevated swelling-

e-effect on the sealing-material, the most

favorable sealing-effect is reached through

relaxation and later after-stretching of the

stuffing-box-glass.

NOA 1 LIP SEAL SET, ROD SEAL

APPLICATIONNormally, NOA1 rings are combined with sup-

port-rings and pressure-rings t sealing sets,

whose construction follows the constructive

and operational realities.

NOA1-sets are been suitable as sealing ele-

ments for rods particularly there where the

maximum pressure becomes effective with

long lifting and relatively high lifting-speed

only over a relatively short working area. The

long lips favor a comparatively good friction-

behaviour on this occasion and are able to

equalize certain leadership-imprescisions

through their flexibility.

MATERIALSNOA1-rings are delivered in WS 071 and WS

072 as standard-implementation in NBR-cot-

ton-fabric-materials. Male- and female adapter

rings are - if the special tools are in stock -

produced in our especially wear-solid hard-

fabric-material WS 090. If special operating-

conditions make it necessary, like for example

higher temperatures, heavy-inflammable

liquids) NOA-sets can be delivered also in for

this case suitable materials. (refer to our

general table for materials).

INSTALLATION TOOLSTo save the thin lips do not use sharp installa-

tion tools and look for insertion chamfers.

If the adapter rings must be manufactured of

metal, following drawing of the measurement

establishing servers:

a = H – h + 0,3 S

R = 0,44 S

An elastomer sealing element which fits into

already existing stuffing box areas without

any changes in construction.

Depending on the respective service condi-

tions (media, temperature, pressure) we are

able to deliver materials based on silicone,

perbunane, EPDM and fluororubber.

The advantage of these seals is a completely

self-acting and maintenance-free functioning.

A mechanical retightening of the seal by con-

necting bushings or screw nuts is not requi-

red. Furthermore, a constructively unavoida-

ble excentrical mismatch of the shafts relati-

ve to their housings is equalized to a certain

rate. Due to the geometrical design of the

inside structure a closed gap is produced

which can be filled with a suitable lubricant

ensuring an extremely high easy-running of

these soft elastomer seals.

RE-rings are so versatile usable (e.g. flat-seals, buffers, shaft-seals) that particularareas of use cannot be established.

The application of these form-pressed orform-poured parts is meaningful howeveronly there, where the low precision and exactdimensioning of stamped or slaughteredrings is not enough.

MMAATTEERRIIAALLSSRE-rings can be delivered in all our materi-als.

TTYYPPEESS OOFF TTOOOOLLSS• tools for rubber materials• tools for fabric materials• tools for polyurethan materials

The delivery-possibility of the RE-rings forthe three material-groups is shown in the fol-lowing dimension table (column: tool-no.). Inthis dimension table, only the profile RE1 ispresented. With demand for the profiles RE2and RE9, we ask you to turn to our technicaladvice.

MATERIALSThe seal has to be chosen with the same care as other construction elements. This applies to the shape and size as well as thematerial which must be suitable for the agent and the conditions of application. The large numer of various agents, pressures andtemperatures has resulted in a multitude of different elastomers and plastics finding their way into sealing-technology. Conversely,the development of modern machines has been significantly supported through advances in the rubber technology which havesimultaneously taken place.

Cross-linkd polymers with the known elastic characteristics are designated as rubber or elastomers. The non-cross-linked raw pro-duct is referred to as caoutchouc. The elasticity of the cross-linked product occurs when the individual polymer chains are pushedagainst one another under stress (tension, pressure), on relief or as a result of the lateral networks more or less returning to theirinitial starting point. Opposed to this, thermoplasts (polyethylene, polystyrene, PTFE) exhibit no lateral networks nor elasticity; theyremain deformed after elongation. Thermoset materials (phenol or epoxy resins), with a high portion of rigid, short networks, beco-me deformed by only a few per cent points.The multitude of available elastomer grades results from the different caoutchouc types which can be made into different materialsthrough corresponding formulations. The task of the mixture development ist to create an elastomer material out of a raw caout-chouc which- due to its chemical structure - has shown certain characteristics, with characteristics that are optimized for the requi-red conditions of application.

Of greater significance ist the resistance of an elastomer to the different agents. With this, two types of transformation occur: phy-sical and chemical processes. The first includes the swelling or shrinkage (change in volume) of an elastomer in an agent. In thecase of swelling, the elastomer absorbs an agent whereby the technical values change, for example, the rigidity values are redu-ced. But this does not mean that the seal would not be able to function. As recommended values, a swelling of 10-25% can be tole-rated with static installation or 4-7% with dynamic installation. The elastomer can be mechanically destroyed by excessive swellingor the increase in volume leads to increased friction so that, for example, pistons can no longer be moved. In the case of shrinka-ge, compounding ingredients are dissolved by the medium. This case is critical for the practical application because through this,under certain conditions, the seal no longer sufficiently lies on the sealing surface and through this, leakage can result. Moreover,the danger of destruction through secondary action exists when, for example, the flexibility to cold deteriorates as a result of a dis-solving action of a plasticizer.

The chemical reaction of the agent leads most often to the destruction of the elastomer in that, through chemical reactions, the poly-mer chain disintegrates, oxidises or is changed in some other way. As a result, the material loses its technological characteristics.

These chemical reactions include ageing due to heat, reactions due to light, ozone and oxygen. The chemical reactivity dependson the structure of the caoutchouc. The mor unsaturated olefin double bonds there are in polymer chains, the easier chemical reac-tions take place (i.e. with NR). A saturated caoutchouc which contains no or only a few reactive double bonds is stable against che-mical reactions (i.e. EPM/EPDM, FPM). NBR, with a mean number of double bonds lies therefore, in respect to for example theheat ageing and the resistance to oxidation, between these extremes. Although CR contains just as many double bonds as NR, thechlorine atoms which are bound to the polymer chain, however, considerably reduce the reactivity.

A similarly simple relation exists also between caoutchouc and swelling in mineral oils and fuels (physical action). Mineral oils andfuels are, chemically seen, covalent compounds of hydrocarbons and therefore, are most compatible with chemically similar, cova-lent caoutchouc with pure hydrocarbon bindings. This consistency results in a good solubility in each other, that is, considerableswelling (i.e. NR, EPM/EPDM). If the caoutchouc contains a rising percentage of polar groups (chlorine, nitrile or ester groups), theswelling reduces accordingly, as is the case with NBR in the series of 18-38% contents of acrylonitrile (ACN). Fluororubber, whichcontains for the most part, fluorine-carbon-bonds show even less swelling in mineral oils. On the other hand, caoutchouc with polargroups opposed to polar solvents (ester, ketone, chlorinated hydrocarbons) are unstable. Hence, it follows that there is no elasto-mer material which is resistant to all polar and to all covalent solvents and their composition (varnish solvents). The silicone rubberwhich possesses no hydrocarbons but rather a silicone-oxygen-skeleton and therefore reacts differently (resistant to mineral oilsand heat / air), is an exception.

MECHANICAL-TECHNOLOGICAL TESTS

Each material is carefully tested before its release and use. Various, important characteristics will be briefly discussed in the follo-wing section.

HARDNESS (DIN 53505, DIN 53519-2)The most common quality of characterization of elastomers is the hardness. It is measured in Shore A or D according to DIN53505. Elastomers are normally tested according to shore A. Above the approximately 95 Shore A, the measurement takes placeaccording to shore D. The two procedures are differentiated by the shaping of the penetration piece and in the spring characteri-sic with which the penetration piece is to be stressed.

Another method ist the determination of the micro-hardness in IRHD according to DIN 53519, which especially finds application insmall sample pieces.

The shore hardness must be adjusted to the pressure demands. The softer the elastomer, the easier it is to be deformed and incertain conditions to be pressed into the opening. On the other hand, thanks to the better flexibility, a softer elastomer seals atlower pressures and on uneven surfaces. For most of the purposes of application, materials with 70 to 90 Shore A have beenwell proven. These types show an optimum of wishes for characteristics. Harder materials often show less elongation and a hig-her compression set. Softer materials are more easily deformed.

TENSILE STRENGTH AND ELONGATION TO TEAR (DIN 53504)Tensile strength and elongation to tear are referred to as comparison values for the characterization of elastomer materials. Inthe installed condition, only small elongations are permitted. Recommended values for the different elastomer types can be seenin the following diagrams.

TEAR RESISTANCE (DIN 53507)Of greater importance for the practical application ist the resistance to tear propagation whereby a cut elastomer part resists thepropagation of the tear whilst unter tensile load.

COMPRESSION SET (DIN ISO 815)The compression set indicates up to which percentage the induced compression of a test piece at a given temperature remainscompressed after the removal of the stress. A small compression set, therefore, means that the material recovers well. This is anadvantage for seals, especially with changing work conditions.

The standard test piece B is a cylindrical disc with a diameter of 13.0+/-0.5 mm and 6.3+/-0.3 mm thick. This test piece is compres-sed by 25% of its thickness (that means 6,0 mm thickness to 4,5 mm). It is stored in this condition for a defined time at a certaintemperature. After expiration of the test time, the test piece is released. After 30 minutes storage at room temperature, the thic-kness is measured (i.e., here 5,7 mm). That means, in this example, the compression set amounts to 20% (remaining deformation0,3 mm in respect to the original included deformation of 1,5 mm)

THERMAL CHARACTERISTICSElastomers exhibit optimal characteristics over a wide range of temperatures and within this area, allow for a long life expectation.There exist, depending on rubber type, two temperature areas in which the characteristics are changed considerably. Below a certain temperature, the glass transition temperature, elastomers lose their elasticity and also their ability to be mechani-cally stressed. This transition is reversible, that is, after warming, the original characteristics are re-established. There are differentmethods for measuring the lower temperature limit, for example, thermoanalytic methods.

The upper temperature limit is determined by each effective agent. The continuos exceeding of the upper temperature limit leads,in contrast to exceeding the lower temperature limit, to non-reversible changes of the elastomer materials. The upper temperature limit is also determined by a weakening of thermoplastic materials. A constantly pass over the upper tem-peratur limit leeds to non reversible changements and therefore to a disruption of the material.

Approvals:With some applications from the multiplicity of the possibilities, for example in the food-area or in the gas-supply, special requestsfor the sealants are to be looked for. Only specially developed materials or materials with the necessary admissions are usable.This requires the corresponding knowledge of the manufacturers.

Application values for the individual material groups in the media water and air can be seen in the following diagram.The high ther-mal expansion coefficient of elastomer materials is to be observed during application. It is between 100 and 160 x 10-6.

FLUID SEALS - SEALING SYSTEMS FOR THE USE IN FLUID APPLICATIONS

Fluid-technology for hydraulics and pneumatics transfers strength and performance to boost, to control and to move.

Consequently it matters to the fluid technology that in determined areas an overpressure is built up and is hold as long as this

requires the function.

Because a simple sealing gap, also as a function of his geometry and the viscosity of the pressure medium, this demand without

leakage does not fulfil, become in most cases contact sealings in use.

The requirements to these sealings or to the used sealing materials are of varied nature:

- avoidance of leakage

- "automatic" reacting to pressure changes

- effectiveness about a wide temperature area

- good slip behaviourness

- high abrasive strength

- compatibility with the pressure media

- material elasticity (to the balance of dimension changes,for example, with expansionsby high pressure)

- controversy with moved sealings: Density versus friction

- compromise between necessary sealing effect and more sufficent lubrication

They form a huge number of factors of influence and their interaction as a basis for an extremely complicated tribological system,

consisting of sealing, countersurface and medium:

- movement speed

- temperature

- viscosity, chemical and physical properties of the medium

- Form and physical properties of the sealing element

- quality of the involved surfaces

- specific installation situation

This requires, on the one hand, a constant advancement of the materials, on the other hand a constant optimisation of the

form of the sealing.

The fluid-technology makes high demands for the developers and manufacturers from sealing systems.

The application fields, for example in mobile and stationary arrangements, agricultural and forest applications, tool machines or in

the air and space technologies are varied broadly and are characterised by most different operating conditions and demands.

Pressures up to 60 MPa (600 cash), temperature areas from-40 to +300 °C, together with other influences of the surrounding put

the range of the application conditions.

To be able to guarantee the functional security the sealing systems have to be chosen material-sided and geometry-sided very care-

fully.

The users expect quick and exact forecasts about the long time behaviour from sealings. On the base of continuous basic research

becomes the knowledge of the tribological procceses an constanty extent and the sealing geometry is in an enduring development

stage e.g. with help of the FEM (Finite elements method).

BASIC MATERIALS

NITRILE RUBBER (NBR)Butadien-acrylonitrile-copolymer with superior resistance to swelling in aliphatic hydrocarbons, normal gasoline and mineral oils.

This resistance against swelling is even more pronounced with an increasing percentage of acrylonitriles, furthermore, the gas den-

sity is improved in this series. On the other hand, the flexibility to cold and compression set improves with an increasing acryloni-

trile percentage. Permanent temperature in mineral oil: 110°C.

Good ageing stability.

Low compression set

Resistant to: Petrol, mineral oil, fuel, dulute acids and alcaline solutions.

Not resistant to: Aromatic hydrocarbons (toluol, xyloles), chlorinated hydrocarbons (tri, per), ketones, esters, ether, brake fluids

based on glycole and hardly combustible hydraulic fluids of the HFD group.

HYDROGENATED NITRILE RUBBER (HNBR)Hydrogenated nitrile rubber (HNBR) is obtained throuth total or partial hydrogenation of nitrile rubber (NBR) whereby the double

bonds in the main chain must be neutralized. The saturated main chain offers a very good resistance to oxidation and chemical

reactions. The nitrile group is responsible for the swelling resistance to oil, fuels and other covalent agents. Emphasis must be pla-

ced on the excellent physical characteristics: the good abrasion resistance, the resistance to hot air and ozone. The resistance

against swelling increases, as with NBR, with the arylonitrile (ACN) content. The application data are the same as for NBR, howe-

ver, a higher resistance to temperature and a substantially better ageing stability is guaranteed.

156

CHLOROPRENE RUBBER (CR)This rubber type is difficult to ignite, shows good elasticity and cold flexibility as well as excellent conduct against weathering and

ozone influences.

Permanent temperature: 100°C

Resistant to: Mineral oil (medium resistance against oil), alcaline solutions and acids, refrigerants (frigenes, freones).

Not resistant to: Aromatic amines, chlorinated hydrocarbons, ketones, esters, ether.

ETHYLENE-PROPYLENE RUBBER (EPM/EPDM)Contains only a low percentage of oxidation sensitive double bonds and through this, has a very good ageing stability and a good

resistance against warmth and ozone.

Very good compression set.

Resistant to: Hot water, vapour (up to 180°C), lees, acids, alkaline solutions, ketones, esters, brake and hydraulic fluids based on

glycole (HFC).

Not resistant to: Petrol, mineral oil, aromatic amines and chlorinated hydrocarbons.

SILICONE RUBBER (VMQ)Through the special chemical formulation with silicone and oxygen atoms, VMQ contains a series of excellent characteristics:

• very resistant to ozone and oxygen

• very good ageing stability

• applicable at dry heat of up to 200°C

• best low temperature flexibility up to -60°C

• low compression set with medium resistance to tear propagation

• very high resistance to tear propagation with higher compression set

Resistant to: Hot air, mineral oils (up to 150°C), water (up to 100°C), aqueos acids and alkaline solutions

Not resistant to: Fuels, aromatic amines, chlorinated solvents, esters, ketones, concentrated acids and alkaline solutions, hot

vapour.

FLUORORUBBER (FKM)Excellent chemical and temperature resistance. Excellent resistance also to oxygen and ozone.

Applicable up to 200°C

Resistant to: Oils, fuels, hardly combustible hydraulic fluids (with the exception of strongly polar types like Skydrol 500A), aromatic

amines, chlorinated hydrocarbons, acids and alkaline solutions.

Not resistant to: Polar solvents (ketones, esters), short chain alcohols (methanol), short chain carbon acids (acetic acid), amines,

ammonia, brake fluids based on glycole.

POLYACRYLATE RUBBER (ACM)Very good heat and oil resistance, even against oils containing additives. Good ageing and ozone stability.

Resistant to: Mineral oils up to 150°C

Not resistant to: Hot water, vapour, aromatic amines, chlorinated hydrocarbons, esters, ketones.

POLYURETHANES (AU, EU)Very good materials which are resistant to wear and structurally stable and which have an excellent elasticity. Due to the high resi-

stance to abrasion they are suitable for rough service conditions.

Resistant to: Mineral oils, normal petrol, type EU also against water-containing hydraulic fluids of the HFA type.

Not resistant to: Hot water, acids, alkaline solutions, aromatic amines and chlorinated hydrocarbons.

RUBBER-IMPREGNATED FABRICSFor seals which are exposed to high mechanical stress (i.e., as a result of high pressure to be sealed) the stability of the pure ela-

stomer is no longer sufficient. For such cases, there are fabric-reinforced materials. The surface structure allows the deposition of

lubricants and with this, promotes the necessary formation of lubricating film between seal and counter surface. In addition to this,

larger housing gaps can be spanned with fabric seals and pressure rings.

Cotton fabric in different strengths and an aramide fabric are available. These are impregnated with NBR, CR and FPM. The app-

lied aramide fabric is distinguished by excellent stability characteristics and a high resistance to temperature. The applicability is

limited in steam, acid and lyes.

THERMOPLASTIC SEALING ELASTOMERSIn this material group it is tried, to infer rubber-elastic properties-elastic qualities with thermo-sculptural processability. This is pos-

sible in different ways.

One of the possibilities is is the mixing of not or only weakly linked up rubber with thermoplasts (blends). As a result you get pro-

cessable thermo-plastical material with the behavior of elastomers. However, these materials have only a subordinated meaning

in the sealing technology.

THE MOST COMMON TPE TYPESOther efforts are linking to a copolymerisation between rubber and thermoplasts, or in using polyamide, polyester or polyurethanein segments. Common characteristics of these combinated copolymers is the physical crosslinking between the intermolecular forces. A chemical interlinking does not take place. The representatives most important for the sealing industry ofthis group are thermo-plastic polyurethanes (TPE U) and the polyetheresters (TPE-E).

TPE-O and TPE-X No chemical cross-linkingTPE-U Thermoplastil polurethanes (AU, EU)Others MPR, EATPE-E PolyetherestersTPA-A PolyetheramidesTPE-S Styrol-triblocked-copolymers

THERMOPLASTIC POLYURETHANES (TPE U)On account of her versatility become thermoplastic polyurethanes (TPE U) more and more used in the sealing industry. Reasonsfor it are the excellent wear-resistance and the extruding resistance of these materials. Also with the tear resistance, the tensilestrength and the elongation to tear, the TPE-U materials have an advantage in comparison to standard elastomers.

For TPE U hard segments and soft segments become tightened about an urethane reaction. The hard segments are able to cry-stalline with themselves. The macromolecules thereby physically link up. At higher temperatures these areas can be broken up.The TPE U can be thereby processed thermo-plastically.

By variation of the hard segments and soft segments a big number of optimised thermoplastic polyurethanes can be realized.Customizing for specific applications or contact medias is possible.

Standard TPE U materials have a very good resistance against mineral oil-basic media. Optimised TPE U are often very good resi-stant to hydrolysis and suitable for HFA-, HFB-, HEES-and HETG liquids. Even for the application in acids and lyes are materialsavailable. Indeed, materials for unpolar media, as a rule, are not suitable for polar media, and vice versa. There is not the univer-sally applicable material existing.

For the fluid power sealing applications common TPE-U materials lie in the hardness area from 80 Shore A to 70 Shore D. Theirapplication temperature area lies with approx. from-35 to 100°C. Optimised materials also leave use temperatures to-50°C or for ashort time up to 145°C.

Thermoplastic polyetheresters (TPE-E)

TPE-E-Materialien also are blockcopolymeres with hard- and soft-segments. They possess very good wear-qualities, high solidi-

ties, a high flexibility and very good constancy against oils and hydraulics-liquids. These materials are not applicable for polar medi-

as as acids, alkalines ord glycoles and temperates above 70°C. Typical TPE-E materials have a hardness between 35 and 75 Shore

D. The temperature range ist between -50°C up to 130°C.

PHYSICAL QUALITIES / MECHANICAL-TECHNOLOGICAL EXAMINATIONSThe judgment of the material-qualities with consideration on the intended application takes place analogously to the elastomeres

For the judgments of the behaviour in cold surroundings, also the TR-10-method is used (after ASTM D 1329).

THERMAL CHARACTERISTICSThermal-plastic elastomers are applicable for a wide range of temperatures. The lower temperature limit is determined by the glass

transition temperature. Below this limit the elastomers lose their elasticity and also their ability to be mechanically stressed. As a

result a leakage or a crash of the seal is possible. The glass transition temperature ist reversible. The upper temperature limit is

determined by melting of the materials and the parts. This deforming is irreversible.

159

PTFE (POLYTETRAFLUORETHYLENE)High temperature resistant plastic. due to extremely low friction, they exhibit no stick-slip effect. Good mechanical and excellent

chemical characteristics.

PTFE (Polytetrafluorethylen) is among the Thermoplasten under the plastics. It is belonging to the fluoride-plastic-group. PTFE is

created from the elements carbon and fluoride through polymerisation, that unites itself during the polymerisation to macro-mole-

cules and forms an unsolvable, part-crystalline plastic.

Applicable for temperatures from -200°C up to +260°C. Resistant to all media with the exception of alkaline metals, fluorine and

some fluorine compounds.

Mechanical properties and heat conductivity are variable by compounding this material with further filling materials.

PTFE SEALING MATERIALSNeside the so-called pure (virginal PTFE) the properties of PTFE can be adapted to different applications due to an appropriate

addition of special fillers. PTFE compounds enlargen the range of application and enable the optimization of the material for a spe-

cific application (e.g. for higher pressures or better abrasion resistance).

PROPERTIES OF PTFE SEALINGS• outstandig resistance to chemicals

• a very high operable temperature range (-200°C up to 250°C)

• a very low abrasion coefficient; even in the case of insufficient lubrication no stick-slip-effect

• antiadesive surface

• not inflammable; in the case of fire contact however toxic fluor gas would escape

• very good electrical insulation properties

• physiological recognized as safe, resistant to atmospheric corrosion and does not absorb water

In the machines and vehicle-construction, the outstanding gliding properties are used for sealings. Within the mentioned tempera-

ture-area, the material doesn't have any chemical changes also in the long run.

Most materials cannot be attached caused by the good anti-adhesion-behavior at PTFE. This has the advantage furthermore that

only low stick-slip effects appear with small relatively-movements. The abrasion rates are very low (0,04 to 0,09).

PTFE is completely fast to light without stabilizers - and UV-staedy. Its behavior is environment-neutral and gives away no pollu-

tants to its surroundings it caused by its insolubility.

No Cadmium, heavy metal-connections, fire-save-medias, FCKW or other toxic substances, are contained in pure PTFE.

APPLICATION FIELDS OF FABRIC-REINFORCED ELASTOMERS

Despite development of the special elastomer materials, these

cannot meet all requests, that are put at sealing-materials in the

heavy-duty-hydraulics and mobile-hydraulics.

For these operating-areas, HECKER can offer sealings from

fabric-reinforced elasomers.

The surface-structure of the sealings makes the storage of lubri-

cants possible and favors the necessary lubricating film with it

between sealing and counter-surface.

Additionally, with fabric reinforced materials and their

high extrusion-force a bigger casing-split than with sea-

lings from pure rubber can be bridged.

As materials, Aramid and cotton-materials are available

with different stitch-wideness and coatings.

With the HECKER-Standard-fabric-materials and

profiles, solutions for most sealing-applications

are possible.

For special-applications can in close cooperation bet-

ween the customer and our development-engineers

particular profiles and special-materials

be developed.

HECKER® HYDRO V HYDRAULIC ROD SEAL (PATENTED)

U-RING IN PERFECTION• highest sealing-effect even n the case of extreme operating-conditions by means of

optimal lip design and supporting elements with sealing function

• permanent good operating behaviour by means of stabilized lubricating film and

exactly defined position in the groove

• low starting friction by means of medium storage within the supporting elements

• supporting elements with storage effect and defined leading-back of the lubricating

film during the return stroke of the rod

• high abrasion resistance, minimal wear

• low compression set, ensuring a long-term sealing function

• uncomplicated installation

FUNCTIONING PRINCIPLE OF U-RINGSU-rings are known as reliable sealing elements for the sealing of rods and plungers with

reciprocating movement.

The contact pressure between sealing lip and rod is decisive for the sealing property of

the U-ring. In order to achieve a high dynamic sealing effect, the sealing lip has to con-

tact the rod only in the area of the sealing edge, independent of pressure or speed.

With regard to a high service safety and a high wear resistance, it is necessary that a

lubricating film is formed in the contact area between sealing lip and rod. This very thin

lubricating film adheres to the rod when it is extended. Leakage-free operation is

guqranteed provided that the lubrication film gets back into the pressure chamber during

the return stroke of the rod.

HECKER® HYDRO V - U-RING IN PERFECTIONDue to the interaction of optimal lip design and supporting elements with sealing func-

tion, the HECKER Hydro V-ring offers the preconditions for high sealing capability and

long service life.

Our developed V-shaped supporting elements guarantee best function of the sealing lip for the whole operating range, as

uncontrolled deformations of the U-ring due to the service parameters (pressure, speed, temperature e.g.) are pre-

vented.

In addition, the function of the U-ring is improved by means of the directional scraping effect of the

V-shaped support elements, leading to higher sealing capability.

When the rod ist extended, the lubricating film is partly scraped away and stored by the v-shaped sup-

porting elements. During return movement, the lubricating film adhering to the rod is directly led to the

sealing lip and forced back into the pressure chamber.

APPLICATIONHECKER® Hydro V-rings are applied for the sealing of rods and plungers with reciprocating movement in

hydraulic systems.
