Ask somebody who knows all about it

Pumps are the main energy users in the industry, while almost every pump drive requires a coupling compensating

or shat misalignment and reducing vibrations causing problems. The coupling can have a major inuence both

on the operating expenses and the service lie o the pump. This is why KTR have extended their product range,

specifcally or pump drives, in recent times, so that they now oer the pump industry a ull portolio o torsionally

exible and torsionally rigid shat couplings, covering very high torque ranges.

Product Manager or the pump industry

For customers requiring a qualifed, technical support and

advisory service, wishing to purchase couplings rom one

single source, we have dedicated product managers or the

pump industry. As a result o this, we not only oer consul-

tation, but detailed support with the selection o the correct

coupling. KTR has sixty specialists working in our design

& engineering department using the latest CAD sotware

which enables us to design customers bespoke solutions

in a matter o hours. KTRs test bench is available or the

testing o entire drive systems including pumps. KTRs in-

ternational presence in every main industrial market assu-

res that users throughout the world get immediate support

whenever necessary.

Perect ft or every size

In addition to our extensive standard range o products, we

develop thousands o customised solutions every year. The

compact, maintenance-ree KTR couplings are used on

every kind o pumps, either or uid or gaseous media, on

vacuum pumps and compressors. Our range o applications

covers everything rom small water pumps to huge irrigating

plants and large turbines. They are also used in nuclear po-

wer stations, with LCD production and isocyanate oaming

processes. Last but not least KTR is one o the leading ma-

nuacturers o shat couplings or the chemical industry.

Our quality management system has been certifed since

1993 to DIN EN ISO 9001 now DIN EN ISO 9000-2000

our environmental management is in accordance with DIN

EN ISO 14001. This means that our couplings have not on-

lybeen tested or quality, saety and environmental compa-

tability, but also satisy the requirements or all preparations

starting with the correct selection o the products and the

reliable handling o orders. In addition, we have approvalsrom most o the main classifcation approval companies.

In our Research and Development Centre we are testing

new products to determine their technical parameters.

Based on such parameters we reproduce simulations o

torsional vibrations that are particularly important or pumps

and compressors. Our inhouse sotware ensures a sae se-

lection o the couplings. It goes without saying that the KTR

couplings correspond to the special requirements o the

pump industry, in particular API 610, 671 and 685.

KTR is actively associated with governing associations, or

example with the introduction o the ATEX product standard

94/9/EC, well-known as ATEX 95. The standard defnes

the use o products in ame-proo areas. We are here to

support you, to make sure that you adhere to every saety

standard and to advise you o the necessary markings. The

ATEX certifcation o KTR couplings or pumps and com-

pressors are listed at www.ktr.com.

KTR oers you an extensive product range o exible and

torsionally sti couplings, with or without a spacer, both

or universal applications and particularly difcult ambientconditions.

z For Pumps:

The torsionally exible jaw coupling ROTEX, the short,

axial plug-in, torsionally exible, ailsae jaw coupling

POLY-NORM and the non-ailsae POLY coupling as well

as the torsionally rigid, backlash-ree steel lamina couplings

RADEX-N and RIGIFLEX-N. The double-cardanic design

was developed particularly or pump drives. It corresponds

to API 610 or 671 and accepts temperatures between

-30 C and 280 C thanks to its all-steel design. For a non-contact torque transmission in pumps or aggressive and

toxic media the permanent magnetic coupling MINEX is

used. DATAFLEX has proven its worth as an accurate

measuring device or development and quality assurance.

z For mobile compressors:

The highly exible ange coupling BoWex-ELASTICor

z For stationary compressors

z For vacuum pumps:

POLY-NORM, MINEX or DATAFLEX

z Innovations and special designs

Pump drives oten require compensation or large shat

displacements, particularly when delivering hot media. This

compensation cannot be guaranteed by single-cardanic

couplings, but only by double-cardanic couplings like

ROTEX ZS-DKM-H which was specifcally developed or

pump drives. This coup ling, which can be disassembled,

is able to compensate or high shat displacements, whilst

at the same time transmitting the torque saely and in this

way increasing the overall service lie o all adjacent compo-

nents and reducing the lie cycle costs (LCC) considerably.Since the shell hubs can be assembled -and disassembled

by means o 4 screws, ROTEX ZS-DKM-H in addition

acilitates the service.

Thanks to our wide range o spider elastomers, the jaw

couplings ROTEX and POLY-NORM meet with numerous

dierent demands. The latest materials are characterised by

highest temperature resistance and excellent resistance to

wear. They are resistant to hydrolysis and chemicals and

have excellent emergency running properties.

Another specifc type is ROTEX FNN with a an either

injectionmoulded or screwed on. The compact system

solution makes a separate an superuous even with high

temperatures. This solution acilitates the assembly, saves

space and cost.

The use o new technologies allows us to oer special types

o steel lamina couplings RADEX-N and RIGIFLEX-N with

highly sti GFK or CFK spacers. This allows us to bridge

large shat distances without causing any weight problems

they are ideal or use on large pumps in irrigation systems.

Most suitable or high torques is the torsionally exible,

ailsae pin & bush coupling REVOLEXKX which can be

used up to 400.000 Nm. It can be plugged in axially and

is extremely short so that it is able to meet very short shat

distance dimensions. REVOLEX KX compensates or axial,

radial and angular shat misalignment. Its elastomer ringsare resistant to petrol and oils and can be replaced whilst

still assembled.

Looking ahead Creating the uture!

The new BoWex GT coupling is closing the gaps between

applications within the pump industry. The new coupling

combines the advantages o the BoWex curved-tooth gear

coupling, customer approved or more than 50 years, with a

constructive novelty: a split sleeve - consisting o two shells.

This allows a new method o disassembly or maintenance

purposes. At the same time, the BoWex GT still achieves a

much higher capacity o radial displacements than conventio-nal products, inline with the double-cardanic principles o the

standard BoWex coupling design.

1,000 cubic metres air per second, 10,000 revolutions

per minute, 500 bar pressure some machines degrade

operating at such fgures unless they are equipped with

the right drive components, e. g. the new RIGIFLEX-HP

high-perormance coupling by KTR. Specifcally developed

or use in high-speed drive trains, RIGIFLEX

-HP con-fdently takes on the biggest o challenges your demand!

Brute orces acting reasonably

... means that the new RIGIFLEX-HP high-perormance

coupling operates as a backlash-ree component. As a

torsionally sti, low-maintenance all-steel coupling this

new design combines maximum stiness with the high-

est possible exibility which is ideal or ast-running drives

where high torque transmission and compensation or shatdisplacements is required. This makes RIGIFLEX-HP the

ideal coupling or all types o gas and steam turbines, high-

speed pump drives, turbo compressors, boiler speed pumps

and generators. Accordingly, suitable applications also in-

clude power station and energy technology, petro-chemistry,

marine technology as well as mining and tunnel building.

With standing the pressure up to 500 bar

High-power compressors oten operate at up to several

hundred bar compressed air. In particular, start shocks can

result in extreme loads and high uctuations in torque which

must be handled competently without damaging the overallsystem. This is where the new RIGIFLEX-HP proves its

worth: oering stability and exibility at the same time. No

matter whether its oil-ree pistons, screw or pendular piston

compressors, industrial gas or processed air compressors,

plunger or turbo compressors: RIGIFLEX-HP confdently

handles and excels under pressure!

Steel laminae coupling


Coupling selection steel laminae coupling

1. Permissible displacements:

Ka: Permissible axial displacementKw: Permissible angular displacementKr: Permissible radial displacement

The steel laminae couplings are selected in a way that the maxi-mum permissible angular excursion Kw may be compensated byevery laminae set. Consequently the maximum permissible angularexcursion of two shafts combined with each other is 2 Kw. The

maximum angular excursion or each laminae set is shown in thetable Technical capacity utilization.

Angular displacement

The permissible radial displacement Kr with distance g o the cou-pling elements is

Kr = g tan (Kw)

Radial displacement

In the table Technical data (RADEX-N page 20/21 andRIGIFLEX-N page 15/16) you can see the max. permissible radialdisplacements Kr or every size and type based on the given stan-dard lengths o the ange hollow shat as well as the permissibleangular displacement Kw o the coupling elements.The max. permissible axial displacements Ka or every size andtype are also mentioned in the table Technical data. The fgureso the permissible displacements indicated are dependent on each

other!With an increasing axial displacement Ka the permissible angu-lar displacement Kw decreases and thus the radial displacement

Kr. (See our mounting instructions www.ktr.com).

3. Drives with periodic torsional vibrations

For drives subject to dangerous torsional vibrations (e. g. dieselengines, piston compressors, piston pumps, generators, etc.) it is

necessary to perorm a torsional vibration calculation (please con-sult with our Engineering Department).3.1 Loading by rated torque

Taking into account the operating actor SB, directional actor SRand temperature actor St, the permissible rated speed must be atleast as large as the rated torque TN o the machine.The nominal torque TKN o the coupling is:

Furtherinormation about this topic under www.ktr.com.

Securing the spacer

Since our main idea with the development o RIGIFLEX-N was to com-ply with the standards o API 610 and API 671, the spacer is securedby a saety catch, too.In case that the laminae break the spacer remains within the coupling.In general the removable part is supplied along with a laminae set pre-assembled by the manuacturer.

RIGIFLEX-N laminae

RIGILFEX-N laminae are waisted laminae sets arranged in layers. Theyare connected to the hubs or anges, respectively, in an absolutelybacklash-ree ft by means o positive-locking set screws.The number o the layers o individual laminae allows to vary torques,displacement fgures and stiness or special designs.

RIGIFLEX-N couplings are used on such applications which require areliable and maintenance-ree torque transmission with shat displace-ment at the same time.RIGIFLEX-N was developped or pump drives in particular. This cou-

pling system corresponds to the regulations o API 610 and may besupplied in accordance with API 671 optionally.(API = American Petroleum Institute)Torques rom 240 Nm to 280.000 Nm are available in 15 sizes oran optimum adjustment to the dierent applications.

Other types

RIGIFLEX-N with spacer rom CFRP

to bridge lager shat distances with a very avourable weight ratio.

Assembly

The spacers o RIGIFLEXR-N have with drawing screws, serving ordisassembly and assembly. The screws make sure that the adapteranges are drawn in the direction o the spacer and consequently slip

o the centering in order to assure a radial disassembly o the spacerincluding the laminae sets.

NON SPARKING LIGHT

Basically the NON SPARKING LIGHT couplings o KTR are providedwith a saety stop as described in the API 671 standard. In this way itis assured that sparks cannot be produced by rotating coupling parts,since the spacer is kept inside the coupling in case that the laminae ails.Furthermore a special washer rom stainless steel 1.4571 ensures thatno sparks can occur in the event o a laminae ailure.

Integrated overload protection

A clamping ring hub with integrated sliding sleeve is used. I too hightorques occur in the drive train, the clamping ring hub slips through onthe shat with the sliding sleeve. The shat is not damaged; the sleeveserves as wearing part that must be exchanged i necessary.The slipping torque can be adjusted through the tightening torque othe clamping screws.

Explosion protection use

RADEX-N couplings are suitable or power transmission in drives inhazardous areas. The couplings are certifed and confrmed according toEC standard 94/9/EC (ATEX 95) as units o category 2G/2D and thussuitable or the use in hazardous areas o zone 1, 2, 21 and 22. Pleaseread through our inormation included in the respective Type Clampingring hubs (clamping hub without dowel screw only or category 3) usedin hazardous areas must be selected in a way that there is a saety os = 2 rom the peak torque o the unit including all operating parame-

ters to the torque o rictional engagement and to the nominal torque othe coupling. Examination Certifcate and the operating and mountinginstructions at www.ktr.com.

HubSpacer

The RADEX-N is a backlash-ree, torsionally rigid and maintenance-ree all-steel coupling. The laminae that are extremely rigid in sense orotation are made rom high-strength, stainless spring steel and enablea compensation or high displacements with low restoring orces. By

reason o the all-steel design the RADEX-N can be used in drives withtemperatures o up to 280 C.

FEM-optimized laminae orm

The steel laminae packings rom stainless spring steel were developedon the basis o FEM calculations. Under consideration o the necessarypossibilities o displacements o the coupling the optimal orm regardingtorque transmission and torsional rigidity was aimed or. The ftted ormo the steel laminae at the outside diameter is the result o this optimi-zation calculation.

Laminae packings with dowel screws

The heart o the steel laminae coupling are the laminae packings andtheir connection to the hubs or spacers. High-strength, special dowelscrew that are alternately screwed with hubs and spacer enable a com-bination o rictional engagement and positive locking. Thus a high powerdensity with simultaneous easy displacement and low restoring orcesis guaranteed. Due to the special constructive design o the RADEX-Ncomponents the laminae packings are artifcially prestressed. Herebythe torsional rigidity o approx. 30 % is enabled and at the same time theknown problem regarding the axial vibrations o the spacer is avoided.

General inormation

Delivery condition

RADEX-N are delivered as individual parts (can be delivered assem-bled on request). The hubs can be supplied unbored or with fnish boreand keyway or with a rictionally engaged shat-hub-connection.The shat-hub-connection needs to be inspected by the customer

(consult with KTR, i necessary).

Assembly and operating advice

(Please see our mounting instructions KTR standard 47110 see www.ktr.com.) For the assembly it is important to make sure that the laminaesets are assembled ree rom distortion in axial direction.

I the fnish bore is machined by the customer, the concentric and axialrunning tolerances have to be observed (see sketch below).

Balancing:

On request o the customer the RADEX-N couplings can be balanced.For most applications this is not necessary due to the accurate machi-ning o the coupling. Please consult with KTR or any urther questions.

Saety regulations:

The coupling must be selected in a way that the permissible couplingload is not exceeded in any operating condition. For that purpose acomparison between the actual loads with the permissible coupling cha-racteristics has to be perormed.The customer must protect rotating parts against unintended touch (Sa-

ety o Machines DIN EN 292 part 2). Please take precautions that thereis a sufcient coupling protection in case o a racture o the couplingcaused by overload.

Installation:

RADEX-N couplings are designed or horizontal installation. Forvertical installation the spacer has to be supported (see sketch below).Please contact.

Spiders our innovation T-PUR

KTR has developed a new standard material or its spiders. The improved polyurethanematerial T-PUR is resistant to signiicantly higher temperatures and has a considerablylonger service lie than the previous polyurethane material. From the visual point o viewwe have characterized the material T-PUR by the colours orange (92 Shore-A), purple(98 Shore-A) and pale green (64 Shore-D). The previous spiders made rom polyure-thane in yellow, red and natural white with green ends will still be available. Up to sizeROTEX 90 inclusive single spiders are used. For ROTEX couplings rom size 100 to180 the spider consists o DZ tooth segments as a standard. The single spider will stillbe available in these sizes as an option.

Explosion-proo use

ROTEX couplings are suitable or power transmission in drives in hazardous areas. Thecouplings are certiied and conirmed according to EC standard 94/9/EC (ATEX 95) asunits o category 2G/2D and thus suitable or the use in hazardous areas o zone 1, 2, 21and 22. Please read through our inormation included in the respective Type ExaminationCertiicate and the operating and mounting instructions at www.ktr.com.

Perormance

In contrast to other lexible couplings, the intermediate members o which are subject tobending stress and are thereore prone to earlier wear, the lexible teeth o ROTEX cou-plings are subject to pressure only. This gives the additional advantage o the individualteeth being able to accept considerably higher loads.The elastomer parts show deorma-tion with load and excessive speeds. Suicient space or expansion should be ensured(see drawing deormation with load).The maximum torsion angle with ROTEX couplings o any size amounts to 5. They canbe itted both horizontally and vertically.

General description

ROTEX - couplings are torsionally lexible and designed or positive torque transmis-sion. They are ail-sae. Operational vibrations and shocks are eiciently dampened andreduced. The two congruent coupling halves with concave claws on the inside areperiphally oset in relation to one another by hal a pitch. In addition, they are designed insuch a way as to enable an involute spider to be located between them.The teeth o the spider are crowned to avoid edge pressure i the shats are misaligned.ROTEX couplings are capable o compensating or axial, radial and angulardisplacements o the shats to be connected.

ROTEX - couplings are characterized by small dimensions, low weight and low mass mo-ments o inertia yet transmit high torques. Running quality and service lie o the couplingare improved by accurate all-over machining.Their application is ideal or transmitting torque while damping torsional vibrations and

absorbing shocks produced by the uneven operation o certain prime movers.

POLY-NORM



Coupling description

Explosion-proo use

POLY-NORM couplings are suitable or the use in drives in hazardous areas.The couplings are certifed according to EC Standard 94/9/EC (ATEX 95)and belong to category 2G/2D, are confrmed and thus suitable or the use inhazardous areas o zone 1, 2, 21 and 22. Please read our inormation in therespective Type Examination Certifcate and the operating and mountinginstructions under www.ktr.com.

Variety o Options

The coupling can be adapted to many applications due to the many options thatare possible with the building block arrangement. The POLY-NORM compo-nents o a given model can be mixed and matched with each other to obtaindierent shat distances using the same basic component.

On request, we can provide customized variations o the POLY-NORM to ftyour needs or example, our POLY-NORM overload coupling with RUFLEXtorque limiter. Just ask us!

General description

The POLY-NORM coupling is a torsionally exible, shear type shat coupling.It has an axial plug-in design with a unique short over all length. The POLY-NORM can be used in nearly all types o machinery and is ideal or the pump

industry.The POLY-NORM coupling compensates or shat misalignment o all kindsand saely transmits the torque.

Function/Design

The coupling consists o two hubs, with fngers separated by elastomericelements. The hubs are assembled blindly plugging the hub fngers into eachother axially and the elastomer ring is trapped in a groove between both cou-pling hubs. The compact POLY-NORM coupling transmits torque with theelastomer in compression.Shat misalignments, vibrations and shock loads are eectively absorbed by thePOLY-NORM.The coupling is maintenance-ree and used in general machinery, the pumpindustry and in compressors. Torques o up to 26,800 Nm are stocked in 17dierent sizes and 7 designs. In addition to the standard coupling models, angedrop out center and spacer options are available in many variations.
