ESCODISC Disc Couplings

Advantages of ESCODISC couplings:

  • Optimized shaped stainless-steel discs for equal load distribution
  • No problems in dirty and corrosive environments due to the use of stainless steel discs and protected bolts
  • AISI 301 Full hard stainless-steel discs
  • Special plated hardware
  • Precisely drilled and reamed flange holes
  • Black oxyded overall steel parts, oiled for protection
  • High torque and high continuous misalignment capacity
  • Maintenance free
  • Very low and predictable reaction forces on associated equipment
  • No disc buckling, no fretting corrosion between the discs
  • Adjustable spacer design for easy accommodating DBSE changes
  • Temperature range -40 °C to 270 °C

DPU - series

Multidisc and flange packed subassembly version with anti-spark and anti-fly (optional)
Torque up to 23,100 Nm
Bore up to 220 mm

Characteristics:

Disc couplings are of an all-metal, non-lubricated design and are torsionally stiff. The torque is transmitted by means of discs, which are alternatively mounted (on the same bolt circle) to the drive and driven flange of the disc pack assembly.

The misalignment capacity depends on the pack thickness, the disc material, the amount of drive bolts and the free span of the material between the drive bolts.

Thetotal torque capacity depends on the disc pack thickness, total number of drive bolts and their bolt circle.

Disc couplings will in most cases have two flexible elements and a spacer. As all parts are positively connected, the disc coupling ensures good inherent balancing properties and is hence often used at motor speeds without any additional balancing. Escodisc couplings meet the API 610 standards. 

The Escodisc DPU series is built around ESCO Couplings genuine and original disc pack sub assembly design. This design with optimized disc shape and thickness, is factory assembled and secured by shipping screws against damages, minimizes assembly errors, simplifies coupling mounting and guarantees worry free performance, low operating costs as well as long life of the connected equipment. 

Advantages:

  • Factory-assembled disc packs secured by shipping screws and thus protected against overstressing/damaging
  • Positive centering and factory-assembled transmission unit minimizing assembly errors and simplifying coupling mounting
  • Fillers avoiding contact between discs hence no fretting corrosion
  • Refurbishment of the coupling by fitting two new disc pack sub-assemblies to the existing spacer piece
  • Easier & less costly mounting
  • Extended life
  • Excellent inherent balancing characteristics
  • S hub for nominal bores and L hub for larger bores

DMU - series

Multidisc pack version
Torque up to 260,000 Nm
Bore up to 370 mm

Characteristics:

Disc couplings are of an all-metal, non-lubricated design and are torsionally stiff. The torque is transmitted by means of discs, which are alternatively mounted (on the same bolt circle) to the drive and driven flange of the disc pack assembly.

The misalignment capacity depends on the pack thickness, the disc material, the amount of drive bolts and the free span of the material between the drive bolts.

The total torque capacity depends on the disc pack thickness, total number of drive bolts and their bolt circle.

Disc couplings will in most cases have two flexible elements and a spacer. As all parts are positively connected, this disc coupling ensures good inherent balancing properties and is hence often used at motor speeds without additional balancing. Escodisc couplings meet the API 610 standards. 

The Escodisc DMU series is built for infinite life and to meet the demands of the market for efficiency, lower maintenance and reduced life cycle costs. It is the ideal solution to a multitude of applications up to 260,000 Nm (and larger upon request), thanks to its high torque, bore and misalignment capacities, its high degree of natural inherent balance (lower AGMA class 9) up to size 85.

Advantages:

  • Unitized disc pack that can be replaced on site
  • Discs with an optimized shape unitized as a pack
  • Fillers avoiding contact between discs hence no fretting corrosion
  • Coasting down torque transmission guaranteeing in case of disc pack failure
  • Easy assembly and disassembly

DMUCC - series

Multidisc pack version with extremely short DBSE
Torque up to 29,600 Nm
Bore up to 350 mm

Characteristics:

Disc couplings are of an all-metal, non-lubricated design and are torsionally stiff. The torque is transmitted by means of discs, which are alternatively mounted (on the same bolt circle) to the drive and driven flange of the disc pack assembly.

The misalignment capacity depends on the pack thickness, the disc material, the amount of drive bolts and the free span of the material between the drive bolts.

The total torque capacity depends on the disc pack thickness, total number of drive bolts and their bolt circle.

Disc couplings will in most cases have two flexible elements and a spacer. As all parts are positively connected, this disc coupling ensures good inherent balancing properties and is hence often used at motor speeds without additional balancing. 

The Escodisc DMUCC series has a close coupled design with a split spacer. Its high torque, bore and its misalignment capacity makes it an ideal maintenance-free alternative for close coupled gear and elastic type couplings and can be modified in such a way that replacement of gear and elastic couplings is possible without modifications to an existing installation.

Its split spacer design allows a disconnection of two machines and replacement of the disc pack without any axial displacement of the connected machines. The Escodisc DMUCC series is the ideal solution for applications up to 29,600 Nm (and larger upon request) with its high degree of natural inherent balance up to size 85.

Advantages:

  • Unitized disc pack that can be replaced on site
  • Discs with an optimized shape unitized as a pack
  • Fillers avoiding contact between discs hence no fretting corrosion
  • Coasting down torque transmission guaranteeing in case of disc pack failure
  • Easy assembly and disassembly

DLC - series

Single disc version
Torque up to 1,600 Nm
Bore up to 105 mm

Characteristics:

Disc couplings are of an all-metal, non-lubricated design and are torsionally stiff. The torque is transmitted by means of discs, which are alternatively mounted (on the same bolt circle) to the drive and driven flange of the disc pack assembly.

The misalignment capacity depends on the pack thickness, the disc material, the amount of drive bolts and the free span of the material between the drive bolts.

The total torque capacity depends on the disc pack thickness, total number of drive bolts and their bolt circle.

Disc couplings will in most cases have two flexible elements and a spacer. As all parts are positively connected, this disc coupling ensures good inherent balancing properties and is hence often used at motor speeds without additional balancing. Escodisc couplings meet the API 610 standards. 

The Escodisc DLC series is built for infinite life and to meet the demands of the market for efficiency, lower maintenance and reduced life cycle costs. They are designed for low to medium torque/speed/duty applications (up to 1,600 Nm) where a maintenance-free coupling is preferred.

Advantages:

  • A single disc concept of optimized shape
  • A simplified design
  • The most economical solution
