VULKAN Flexible Couplings, Replacement Elements & Power Transmission Solutions in the Middle East

Do you need a VULKAN coupling, replacement rubber element, coupling spare part or complete replacement coupling for an existing machine or vessel?

METAL Mobility Group supports customers across the GCC, Middle East and Africa with VULKAN coupling solutions for marine propulsion, diesel generator sets, industrial drives, pumps, compressors, power generation and other demanding mechanical power transmission applications.

Whether you are dealing with a failed coupling, worn flexible element, planned maintenance, emergency spare requirement, coupling retrofit or a new equipment project, the correct coupling should be selected according to the actual application—not simply by matching the outside dimensions.

VULKAN’s portfolio includes highly flexible couplings, flexible couplings, rigid couplings, fluid couplings, propeller-shaft couplings and other drivetrain technologies for marine and industrial applications.

Need a genuine VULKAN Coupling or Spare Part?

A VULKAN coupling can be found between the engine, gearbox, generator, pump or other rotating equipment in many types of machinery.

Typical requirements we support include:

• Replacement VULKAN coupling
• VULKAN rubber elements
• Flexible coupling elements
• Coupling hubs and flanges
• Coupling bolts and associated hardware
• Complete coupling assemblies
• Coupling retrofit requirements
• Replacement for older or difficult-to-source models
• New machinery coupling selection
• Marine propulsion coupling requirements
• Generator and industrial drive couplings

When the original part number is available, identification can be straightforward. When it is not, photographs, nameplate information, dimensions and application data can help us investigate the requirement.

VULKAN Couplings for Marine Applications

VULKAN has a long-established presence in marine drive technology, with highly flexible couplings and other drivetrain components used across vessel types including tugs, workboats, ferries, cruise ships, yachts, dredgers and other commercial and special vessels.

Marine applications may include:

• Main propulsion systems
• Auxiliary engines
• Diesel generator sets
• PTO / PTI systems
• Pump drives
• Waterjet propulsion
• Hybrid propulsion systems
• Marine gearbox connections
• Cardan shaft drives
• Shaft line systems
• Workboat and offshore vessel drives

For marine applications, coupling selection is influenced by engine type, gearbox characteristics, torsional vibration behaviour, misalignment, speed, transmitted torque and installation arrangement.

VULKAN’s marine portfolio includes highly flexible couplings such as RATO, VULASTIK L, VULKARDAN and MEGIFLEX, as well as shaft-line and related drivetrain solutions.

VULKAN Couplings for Diesel Generator Sets

Generator sets are particularly sensitive to torsional behaviour within the engine-generator drive system.

The appropriate flexible coupling can help accommodate shaft movement and contribute to the required torsional characteristics of the complete drive.

VULASTIK L, for example, is a highly flexible coupling available in different rubber and silicone characteristics and is designed for applications including power generation, auxiliary drives and bell-housing installations.

The newer VULASTIK L XT extends the VULASTIK L range into higher torque applications and is intended for applications including gensets and pump drives.

For generator coupling selection, useful information includes:

• Engine make and model
• Engine power
• Rated RPM
• Generator make and model
• Coupling model
• Existing element specification
• Flywheel and SAE dimensions
• Installation arrangement
• Photographs of the existing coupling

VULKAN Couplings for Industrial Drives

VULKAN also supplies coupling technologies for demanding industrial and energy applications.

VULKAN identifies industries including oil & gas, mining and mineral processing, power generation, iron and steel, construction and cement, ports and bulk material handling among its industrial applications.

Potential applications include:

• Pumps
• Compressors
• Fans and blowers
• Turbines
• Conveyors
• Heavy machinery
• Power generation equipment
• Industrial engines
• Material handling systems
• Oil & gas equipment

Depending on the application, the appropriate solution may be a highly flexible coupling, flexible coupling, disc coupling, fluid coupling or another drivetrain configuration.

For example, VULKAN’s DISCFLEX range is intended for industrial applications such as pumps, compressors, fans, blowers and turbines, with designs offering high torque and speed transmission and suitability for environments where elastomeric couplings may not be appropriate.

Which VULKAN Coupling Do You Need?

VULKAN has a broad coupling portfolio, so selecting the right series requires understanding the machine and operating conditions.

VULASTIK L

A highly flexible, compact coupling for applications including bell-housing installations, rigid-mounted engines, auxiliary drives and power generation.

VULKARDAN F

A highly flexible coupling designed for flexibly mounted drive systems, with a compact design and capability to compensate radial, axial and angular shaft offsets.

MEGIFLEX B

A versatile highly flexible coupling for lower-power diesel main and auxiliary drives, including marine and industrial applications. VULKAN also identifies applications such as primary drives with smaller pods and PTO/PTI-connected units.

RATO R / R+

Highly flexible couplings developed for drive systems requiring high torsional flexibility and good displacement characteristics, including high-speed main and auxiliary drives.

RATO S / S+

High-torque flexible couplings designed to compensate radial, axial and angular shaft displacement, with different torsional stiffnesses and damping characteristics for torsional-vibration tuning.

RATO DS / DS+

Highly flexible couplings developed particularly for rigidly mounted marine main propulsion engines, with torsional flexibility and backlash-free torque transmission.

DISCFLEX

Metallic disc coupling solutions for industrial applications including pumps, compressors, fans, blowers and turbines, particularly where high speed, high torque or demanding environmental conditions need to be considered.

VULKAN’s current portfolio also includes FLEXOMAX, DENFLEX, fluid couplings, propeller-shaft couplings and other specialized drivetrain solutions.

VULKAN Coupling Replacement & Spare Parts

For an existing machine, you may not need a complete new coupling.

Sometimes the requirement is simply:

“The coupling element has failed. We need the replacement.”

Common VULKAN spare requirements include:

• Flexible rubber elements
• Torsional elements
• Coupling hubs
• Flanges
• Bolts/ Fastners
• Membrane components
• Coupling accessories
• Replacement assemblies
• Older-model replacement parts

However, replacing only the flexible element without confirming the application can create problems.

The replacement should be checked against the existing coupling and machine requirements, including:

• Coupling model
• Size
• Element type
• Rubber hardness / stiffness where applicable
• Torque
• RPM
• Shaft arrangement
• Misalignment
• Operating temperature
• Installation configuration

VULKAN Coupling Replacement for Older Equipment

Many vessels and industrial machines continue operating for decades.

During their service life, the original coupling may become:

• Worn
• Damaged
• Obsolete
• Difficult to identify
• Difficult to source
• No longer commercially available in the original configuration

This is where technical identification becomes important.

If you do not know the exact VULKAN part number, send us:

Existing coupling photographs + nameplate + drawing + application + engine/gearbox details

Our team can review the available information and investigate the appropriate VULKAN replacement or spare requirement.

Marine Coupling Replacement & Retrofit

Marine customers often need replacement couplings during:

• Dry docking
• Planned maintenance
• Major overhaul
• Engine replacement
• Gearbox replacement
• Propulsion system modification
• Emergency repair
• Vessel refurbishment
• Hybrid-drive upgrades

A coupling that physically fits is not necessarily the correct coupling.

Marine coupling selection should consider the engine characteristics, gearbox, shaft line, torsional vibration requirements, alignment, torque, speed and installation arrangement.

For complex marine applications, VULKAN provides technical engineering support including torsional vibration analysis and calculation services as part of its marine technology activities.

VULKAN Couplings for Hybrid & Modern Marine Drives

Marine propulsion systems are increasingly incorporating hybrid and electric drive architectures.

VULKAN states that its flexible couplings and mounts are used across diesel-mechanical, hybrid and electric marine drive concepts, with solutions including MEGIFLEX B, VULKAN mounts and hybrid drive components.

This can create coupling requirements during:

• Propulsion upgrades
• Hybridization projects
• Diesel-electric systems
• PTI/PTO installations
• Generator integration
• Electric motor integration
• Existing vessel modernization

For such applications, coupling selection should be based on the complete drive architecture rather than replacing the existing component on a like-for-like dimensional basis.

VULKAN Couplings, Cardan Shafts & Complete Driveline Support

A coupling is often only one part of a complete drivetrain.

A typical marine or industrial drive may include:

Engine → VULKAN Coupling → Gearbox → Cardan Shaft → Driven Equipment

An equipment upgrade may therefore require several components to be reviewed together.

METAL Mobility also supports customers with related mechanical drive system requirements, including:

• Cardan shafts / drive shafts
• Industrial gearboxes
• Marine transmissions
• Flexible couplings
• Industrial brakes
• Safety brakes
• Torque limiters
• Clutches
• Universal joints and driveline components

This allows us to look at the complete mechanical power transmission system, rather than treating the coupling as an isolated component.

New Equipment & OEM VULKAN Coupling Applications

VULKAN couplings are used across marine and industrial drive systems, and coupling selection should ideally be considered during the equipment design stage.

METAL Mobility can support new equipment enquiries involving:

• Marine propulsion
• Workboats
• Tugs
• Fishing vessels
• Generator sets
• Pumps
• Compressors
• Industrial engines
• Power generation
• Industrial machinery
• Special-purpose equipment

For a new application, provide the available power, RPM, torque, shaft arrangement, engine/gearbox details and installation dimensions.

Where the application requires detailed engineering, the requirement can be coordinated for appropriate technical evaluation.

How to Identify Your VULKAN Coupling

Don’t have the part number?

You may still be able to obtain a replacement.

The following information can help:

Existing coupling

• VULKAN model / type
• Size
• Part number
• Commissioning number
• Nameplate/ photographs

Machine

• Engine make and model
• Gearbox make and model
• Motor power
• Operating RPM
• Application

Photographs

Clear photographs showing the coupling from different angles can be extremely useful.

A photograph + model/nameplate + application details is often a good starting point for identification.

Why Customers Contact METAL Mobility for VULKAN Requirements

When a coupling fails, customers are not simply looking for a catalogue.

They usually need answers to practical questions:

Can I get the replacement element?

Do I need the complete coupling?

Is my existing model still available?

Can the current coupling replace the older version?

Can I use an alternative configuration?

What information is required for technical selection?

Can the component be supplied before my vessel or plant shutdown?

Our role is to help investigate the actual requirement and identify the appropriate route for new equipment, replacement, retrofit or spare-part supply.

Need a VULKAN Coupling or Replacement Part?

Whether you are maintaining a commercial vessel, tug, workboat, generator set, pump, compressor, power plant, industrial drive or other rotating equipment, don’t select a replacement coupling based only on appearance or dimensions.

The correct coupling depends on the power, speed, torque, torsional characteristics, misalignment, shaft arrangement and operating conditions of the machine.

Send us what you have:

Existing VULKAN model / part number + application + power + RPM + dimensions + plant/ vessel details + photographs

Even when the original part number is unavailable, we can start with the available equipment information and investigate the requirement.
