Operating Limits The TS20 / TS20R series offers proven sealing reliability for general industrial pumping systems handling corrosive and high-purity fluids. With options like filled PTFE and SiC sealing faces, these seals provide excellent chemical resistance and reduced friction, making them ideal for chemical processing, pharmaceuticals, and water treatment applications. Designed to function as a direct replacement for John Crane Type 20 and 20R, the TS20 features an integral rotary face while the TS20R uses an insert rotary face for easier maintenance and cost-effective part replacement. Engineered for stability under moderate pressures and speeds, these seals help extend pump life while minimizing leakage and operational downtime.
