Properties

  • Design:
    • two precision machined coupling hubs
and precision spacer tube mounted
to the disc packs by means of high
strength screws and bushings for alignment and frictional clamping of the
assembly.
    • axial retention with DIN 916 set screws.
  • Material:
    • disc packs: highly elastic, corrosion resistant spring steel

    • hubs and spacer: high strength steel
  • Features Model Model LPA:
    • meets all requirements of API 610
    • intermediate tube removable without disturbing adjacent equipment
    • integral safety catch in case of disc pack rupture
    • ISO G6.3 / AGMA class 9 minimum balance quality
    • highly customizable
