Chesterton products – Chesterton DualPac® Packing Technology
A sugar mill was trying to seal heavy slurry (63% solids) in multiple centrifugal pumps. The original packing was deforming under pressure after only three weeks and the mill was unable to control the leakage. Instead, Chesterton DualPac® 2212 packing was installed with the hopes of maintaining a five-week packing life to better seal operation.

A sugar mill was trying to seal heavy slurry (63% solids) in multiple centrifugal pumps. The pump packing in use lasted on average only three weeks. The plant considered the impact on these applications as a major reliability issue.
Packing was deforming under pressure and the mill was unable to control the leakage. The customer’s goal was to increase the packing life to five weeks to support the existing plant cycle.
