S Series
Slurry Seal
Industrial seals modified and redesigned from seals for track rollers
Hard metal alloy is used as the sliding material, and the seal cover is integrated into the component parts. This design facilitates equipment machining, and eliminates the need to ensure equipment precision.
This series offers seals of relatively large diameters, and is mainly used in large pumps for irrigation, pumps for marine civil engineering, and process pumps for coal liquefaction, etc. The demand for these industrial slurry-resistant seals has been growing.
Feature
- Consists of two main parts: O-ring and seal ring. Simple structure minimizing problems and ensuring easy handling
- O-ring serves as the packing; rubber elasticity used to provide a spring force; rubber friction ensures anti-rotation
- Special nitrile rubber characterized by minimal permanent strain used as the standard O-ring material
- Shrink-fit structure employed for the seal ring. Standard materials: highly corrosion resistant stainless steel for the metal parts, and hard metal alloy (characterized by superb corrosion resistance and wear resistance) for the sliding material
- Titanium/Silicon carbide structure for special conditions
- Can be adopted under positive pressure or under back pressure
