Benefits

  • The single cartridge seal can be connected in accordance with all common API Plans, such as 01, 02, 11, 31, 32 + 61 (62) and 23 + 61 (62). The seals are available for all of KSB's API pumps.
  • The throttling bush enables connection of a gas, steam or liquid quench, depending on the seal variant. This prevents outboard deposits at the seal, for example.
  • The API Plan combination 02 + 23 with high-efficiency pumping ring is perfectly matched to applications handling hot fluids.
