A.W. Chesterton Company introduced the 170L Slurry Cartridge Single Seal, which, the company reported, is engineered to operate reliably in severe slurry environments without external seal flushes. The seal is designed for Warman AH series pumps. It eliminates the need to dimensionally check each pump, as well as any modifications to the pump. The seal uses a single clamping screw, which prevents equipment shaft damage and simplifies seal removal in sticky or viscous fluids, or where solids have a tendency to clog standard set screw designs. It can help reduce water costs where clean water is scarce or costly, the company reported.
