혜택

  • The double cartridge seal is especially designed for use in the standardised seal installation spaces of the non-API pump MegaCPK (CPKN + CPK possible).
  • The double cartridge seal can be connected in accordance with all common API Plans, such as 01, 02, 11, 31, 32 + 52, 53 (A, B).
  • The space between the two mechanical seals is flushed with a buffer or barrier fluid, depending on the application. This completely absorbs any leakage of the fluid pumped. In addition, the heat is transported away from this area.
