  • Page 8: Technical Data

    The technical data to the ARPEX couplings listed in these instructions are documented on the order­specific drawing of the coupling (see "Operating and Coupling Data" fields in figure 1) and in the current product catalogue and are available on request or can be accessed at any time on the Internet (see cover at back).

  • Page 9: General Notes

    – The coupling is designed only for the application specified in the order. Other operating conditions are regarded as incorrect. The "FLENDER coupling" described in these instructions has been developed for stationary use in general engineering applications. The coupling serves to transmit power (torque and speed) between two shafts or flanges connected by this coupling.

  • Page 10: Safety Instructions

    DANGER Danger of explosion Risk of explosion when using unsuitable components in potentially explosive areas. Use the coupling only for the approved zones and equipment groups. In case of doubt, contact Flender. DANGER Danger of explosion Risk of explosion when operating in potentially explosive areas.
  • Page 11 Flender will assume no liability or guarantee for damage caused by spare parts not supplied by Flender. The same applies to any accessories not supplied by Flender.

  • Page 12: Transport And Storage

    Scope of supply The products supplied are listed in the dispatch papers. Check on receipt to ensure that all the products listed have actually been delivered. Parts damaged and/or missing parts must be reported to Flender in writing immediately. Transport Different forms of packaging may be used depending on the size of the coupling and method of transport.

  • Page 13: Storage Of The Coupling

    The coupling is delivered in a preserved condition and can be stored in a covered, dry place for up to 6 months. If the unit is to be stored for a longer period, it should be treated with a long­term preservative agent (Flender must be consulted). Correctly stored couplings retain their properties unchanged.
