FLENDER N-EUPEX Pin Coupling

  • Damping shaft coupling that can be used universally to compensate for shaft misalignment
  • Nominal torque range from TKN = 19 Nm up to 62,000 Nm with 23 sizes
  • Temperature range: from –50 °C to +100 °C

Due to their torsional flexibility N-EUPEX couplings offer the possibility of moving critical torsional vibrations from the operating area of the mechanical equipment in such a way that no negative effects on the drive train are to be expected. N-EUPEX couplings are made of high-quality cast iron. The flexible elements made of synthetic rubber (buna N) are available in different degrees of hardness for many applications. Metal pins and flexible elements are so designed that no wear occurs when properly fitted.

Advantages of the product

  • Torsionally rigid and damping pin coupling to be used universally for compensating shaft misalignments
  • Maximum operational reliability, since fail-safe
  • Suitable for plug-in assembly and simplified replacement of elements in the type consisting of three parts
  • Dynamic adaptation by selection of elastomer hardness
  • Torque range from 19 Nm up to 62,000 Nm for 23 sizes and 10 different types
  • Can be used in potentially explosive atmospheres; certified acc. to nach 2014/34/EU (ATEX)
  • High degree of availability of parts ex stock

Examples of application

  • Mining and Cement: heating technology
  • Oil and Gas: pumps, fans, compressors, air condensers
  • Power Generation: pumps, fans, compressors, air condensers, water turbines
  • Chemicals and Pharmaceuticals: driers, lauter tuns, pumps, fans, compressors, mixers, agitators, reactors
  • Plastic and Rubber: single- and double-screw extruders
  • Pulp and Paper: wastewater purification plants
  • Water and Wastewater: aerators
  • Food and Beverage: lauter tuns, reactors, agitators, Mixers

Further application-related coupling types are available. Please feel free to contact us.

Did you know?

Original FLENDER® elastomers ensure the optimal operation of your system. The flexible elements of the N-EUPEX coupling are subject to compression. If the flexible elements are irreparably damaged, the hub parts come into contact with metal. This “emergency operation capability” is required, e.g., in the case of fire pump drives.
