The 20 and 20R Mechanical Seals are high-performance industrial sealing solutions designed as direct replacements for John Crane Type 20 and 20R. These models are widely used in industrial pump systems handling corrosive and high-purity fluids, delivering reliable and efficient sealing performance.
The TS20 features an integral rotary face design, while the 20R is equipped with an insert rotary face, providing flexibility in selection based on system requirements and maintenance preferences. Both variants are engineered for durability, stability, and ease of installation.
With advanced material combinations such as filled PTFE, silicon carbide, and ceramic, these seals offer excellent chemical resistance, reduced friction, and long service life, making them ideal for demanding industrial environments.
