N-ARPEX ALL-STEEL COUPLING

 

Description:

Low investment costs, lifecycle costs, power-to-weight ratio, fitness for use and the cost of purchasing couplings are key considerations for equipment manufacturers.

With the introduction of the new N-ARPEX® all-steel multi-disk coupling Flender is continuing the success story of the proven ARPEX® series of couplings. The N-ARPEX is currently the most powerful coupling on the market due to the consistent further development of the ARPEX – a leap in performance that in this size could only be achieved by means of various design features. With the N-ARPEX, Flender delivers the optimum price-performance ratio.

With our all-steel couplings, the reliable transmission of torque between the shafts to be connected is backlash-free, torsionally rigid and flexurally elastic. This enables them to compensate for axial, angular and radial misalignment. Our multi-disk couplings are not prone to wear and are maintenance-free.

The couplings have been designed for use in potentially explosive environments as defined in Directive 2014/34/EU (ATEX) and comply with the requirements in standards API 610 and API 671.

 

use:  
  • Petrochemistry: pumps, fans, compressors, air condensers, jack-up rigs, driers, mixers, cooling towers, agitators, reactors, installation vessels
  • Power Generation: air condensers, generators, gas turbines, cooling towers, water turbines, boiler feed pumps
  • Pulp and Paper: waste paper, wet section, dry section, smoothers and cylinders, reel winders, coating machines, calenders, wastewater purification plants
  • Water and Wastewater: pumps, aerators, water screw pumps
  • Cranes: hoisting and luffing gear systems, slewing gear systems, trolley and travel gear systems
  • Marine and Shipbuilding: single-engine ships, multi-engine ships, dredgers, generator gearboxes, installation vessels.

ELPEX-B RUBBER TIRE COUPLING

 

Description:

Flexible and adaptable

Highly flexible ELPEX-B® couplings transmit torques without circumferential backlash in machines with non-uniform torque characteristics. They are resistant to wear and maintenance-free. The hubs of the ELPEX-B couplings are made of high-quality cast iron or steel. The torque is transmitted by a flexible tire reinforced with a cord ply.

 

Your benefits at a glance

  • Compensation of very large shaft misalignments
  • Independent of direction of rotation (suitable for reversing operation)
  • The rubber tire can be replaced easily without the need to move the coupled machines
  • Easy mounting on the shafts is possible with taper bushes.

 

Features:
  • Highly flexible, backlash-free tire coupling
  • Nominal torque range from TKN = 24 Nm up to 14,500 Nm with 15 sizes
  • Temperature range: from –50 °C to +50 °C for natural rubber materials, from
    –15 °C to +70 °C for chloroprene rubber

  • Small dimensions, low weight and low mass moments of inertia are achieved by means of an intelligent design and combination of materials
  • Large safety reserves even at high shock loads
  • Maximum operational reliability through optimal tooth shape and use of high-quality materials
  • Suitable for horizontal mounting and, with a special design, for vertical mounting
  • Suitable for use in potentially explosive environments; certified according to 2014/34/EU (ATEX)

 

Features:
  • Double-jointed gear coupling
  • Nominal torque range from TKN = 1,020 Nm up to 162,500 Nm with 12 sizes
  • Temperature range: from –20 °C to +80 °C

BIPEX-S CLAW COUPLING

 

Description:

​In the area of backlash-free couplings we offer you a large range of types and sizes in the two model ranges BIPEX-S® und SIPEX® for problem-free installation. The vibration-damping and electrically insulating plug-in BIPEX-S elastomer coupling is almost completely maintenance- and wear-free and has an exceedingly low moment of inertia. It is very compact, suitable for a range of installation requirements to different hub versions, and very easy to install.

The BIPEX-S coupling is made up of two aluminum or steel hubs and a polyurethane cam ring. Different cam ring hardness ratings allow the damping ratio and the torsional stiffness to be varied.

 

Your benefits at a glance

  • Large variety of design options for maximum flexibility
  • Rotational speed: max. 47,500 rpm
  • Compensation for shaft misalignments
  • Low moment of inertia
  • Suitable for highly dynamic applications
  • Vibration-damping.

 

Features:
  • Vibration-damping and electrically insulating claw coupling
  • Nominal torque range from TKN = 0.5 Nm to 655 Nm with ten sizes
  • Temperature range: from –50 °C to +120 °C
