Specifications
- Configurable flange connections
For API Plans 11, 12, 21, 22, 31, 32, 41 + 61 (62) and 23 + 61 (62). - Fixed throttling bush
Optionally floating. - Three strong torque transmitting elements
For transmitting the rotation and for vibration damping. - Seal face material
Combination of hard and soft materials, e.g. silicon carbide and carbon graphite, which is highly resistant to blistering. - Multi-spring arrangement
Made of C276 alloy - Rotating flexible elements
With O-ring as secondary seal. - Optional cooled gland packing chamber
(Plan 02) and connections for Plan 23 with highefficiency pumping ring 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.
