The sliding material is made of a combination of hard materials, and a knife edge is provided on one side. This seal is structured so that the spring does not touch the fluid. It is suitable for handling high viscosity fluids, polymerized fluids and slurry-contained fluids.
Pumps handling high-viscosity fluid, polymerized fluid, and fluid that contains slurry (synthetic fiber, pulp and paper, food, paint, resin, rubber, etc.)
