Specifications
- Special design
Special single mechanical seal for seawater applications, bi-directional, tailored to the seal installation space of the pump. - Circulation
The ribs on the shaft sleeve support circulation of the fluid handled in the clearance between the impeller and the pump casing. - Dependable
Stationary design, balanced, multiple springs located outside the fluid handled. The springs are insensitive to contamination and provide uniform surface pressure across the seal faces, thus ensuring a long service life. - Compact
The pump‘s shaft sleeve is integrated in the mechanical seal. - Service-friendly
Easy to install, no adjusting dimension required
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.
