Specifications
- Compact
Single, balanced cartridge seal, bi-directional, tailored to the seal installation space. - Service-friendly
Easy to install, no adjusting dimension required Easy installation and removal also under difficult operating conditions. - Versatile
For all operating conditions the submersible motor is approved for. - Tailored
The permissible spring travel accommodates for the technical requirements of the motor shaft and thrust bearing. Depending on the size, the sleeve of the mechanical seal also houses the connection between coupling and pump, thus keeping the shaft dry. - Dependable
Stationary design; the multi-spring arrangement provides uniform surface pressure across the seal faces, thus ensuring a long service life
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.
