Specifications
- Compact
The perfect match for HPH hot water pumps. The design is tailored to the cooled pump cover. - Robust
This robust seal is designed for operating conditions with extremely high pressures and temperatures. - Safe
The solid seal faces abut the metal components and are thus axially secured. This prevents tilting of the seal faces. This ensures reliable sealing and low wear also in extreme conditions - Dependable
The special design with hook sleeve does away with the need for an axial adjusting dimension; the seal is always perfectly positioned on the pump shaft. - Durable
This high-quality sealing solution ensures reliable pump operation and 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.
