Robust mechanical seal 4kbl
Single mechanical seal, bi-directional and balanced.
Tailored to the seal installation space of the pump, suitable for fluids with high solids content.
Dependable mechanical seal 4kbl
Dynamic design, multiple springs located outside the fluid handled. The springs are insensitive to contamina- tion and provide uniform surface pressure across the seal faces, thus ensuring a long service life.
Different material variants mechanical seal 4kbl
The mating ring can be made of tungsten carbide or, alternatively, silicon carbide. Elastomers are available in FKM or, alternatively, perfluoroelastomer (FFKM).
Service-friendly mechanical seal 4kbl
Easy to install, no adjusting dimension required
Compact mechanical seal 4kbl
The pump’s shaft protecting sleeve is integrated in the mechanical seal.
