Robust
Single mechanical seal, bi-directional, tailored to the seal installation space of the pump. Suitable for fluids with high solids content.
Dependable
Stationary design, balanced, multiple springs located outside the fluid handled. The large springs are insensitive to contamination and provide uniform surface pressure across the seal faces, thus ensuring a long service life.
Versatile
Can optionally also be operated with unpressurised quench liquid.
Different material variants
Primary and mating rings made of silicon carbide or, as special variant, tungsten carbide springs made of 1.4310, alternatively available made of Hastelloy as special variant.
Service-friendly
Easy to install, no adjustments required when installing.
