Applications 4EDTR6HT & D

API 682 applications in the chemical and petrochemical industries

Design 4EDTR6HT & D

  • Double cartridge seal

Technical Data 4edtr6ht & d

  • Pressure: Up to 20 bar
  • Temperature: -75 to 400 °C

Benefits 4edtr6ht & d

The double metal-bellows seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 52, 53 (A, B, C) and 23 + 52, 53 (A, B, C). The seals are available for all of KSB’s API pumps.

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. The double pressure balanced mechanical seal can be operated with pressurised barrier fluid or unpressurised buffer fluid.

The mechanical seal is available in a hard-soft combination of silicon carbide and carbon graphite, or in a hard-hard combination of silicon carbide and silicon carbide. The bellows made of Inconel® 718 and the secondary sealing elements made of pure graphite have an excellent chemical resistance and are especially suited for applications with high temperatures.
