- Balanced mechanical seal
- Sealing type Mechanical seal
- Double
- Max allowed fluid temp TSG

Benefits
- The double metal-bellows 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.
