Specifications
- Dependable
Single mechanical seal, tailored to the pump requirements. Robust and practical. - Compact
The pump‘s spacer sleeve is integrated in the mechanical seal. - Versatile
Optimally designed with one seal type covering all of Omega‘s applications. - Easy to install
No adjusting dimension required for installing the mechanical seal. The primary ring is kept in position in the torque-transmitting element for transport and installation. - Different material variants
Elastomers made of EPDM or FKM. Metal parts available in super duplex stainless steel (1.4501) for seawater applications.
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.
