Main Applications
- API 682 applications in the chemical and petrochemical industries
Technical Data
- Cartridge seal
- Yes
- Design
- Dynamic
- Balancing
- Balanced mechanical seal
- Sealing type
- Double
- Maximum allowable fluid temperature
- 200 °C
Benefits
- 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, 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.
