DualPac® 2212
Chesterton DualPac 2212 combines a durable mechanical packing ring with an advanced injectable sealant to provide dual-layer sealing without requiring water flush systems or equipment disassembly. The outer mechanical ring delivers immediate sealing performance, while the injectable compound can be added during operation to extend seal life, prevent leaks under pressure, and maintain consistent performance in challenging conditions.
Designed for use in pumps, mixers, and agitators across food, chemical, and general industrial applications, DualPac 2212 is capable of handling pressures up to 150 psig, shaft speeds up to 6 m/s, temperatures up to 400 °F, and a broad pH range. This dual-component sealing solution reduces maintenance requirements, minimizes downtime, delivers reliable continuous sealing, and protects shafts and critical components in demanding industrial environments, providing long-term operational efficiency and durability.
