Specifications
- Compact
Single cartridge seal, bi-directional and balanced. - Robust
The materials and design ensure a long service life. The mechanical seal features threaded connections for flushing out leakage at the atmospheric side. - Service-friendly
Tailored to the seal installation space and pump requirements. Easy installation; the assembly fixtures provide for safe transport and pre-centring for installation. - Increased safety
An integrated, floating throttling ring provides additional safety in the event of leakage. - Dependable
Stationary design, multiple springs located outside the fluid handled
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.
