Pulp and Paper Plant Installs DualPac® 2211 Packing in Leaking Stuffing Boxes


Chesterton products – Chesterton DualPac® Packing Technology




A customer working in a pulp and paper causticising plant was struggling with leaking stuffing boxes with competitors’ packing products. With leakage contaminating bearings, it costed the customers time and money replacing and maintaining equipment. A Chesterton expert installed the DualPac® 2211 Packing to extend the packing life and increase efficiency.

DualPac 2211


A pulp and paper causticizing plant in Europe has three double-sided screw conveyors transporting very abrasive lime slurry at 122°F (50°C). The rotational speed is 50 rpm.

The stuffing boxes were previously packed with various competitors’ packing products. Leakage usually occurred a few days after installation and the gland needed adjustment.

The leakage contaminates the bearings, which must be replaced annually.

The conveyor needed proper packing to eliminate leaks.


The stuffing boxes were repacked with DualPac® 2211 Packing.

The leaking stuffing box was contaminating the bearings.


The DualPac® Packing extended the packing life by 4X. The plant saved $657 US/year ($900 AUD/year) less the cost of a product and avoided significant downtime and maintenance.

The packing life was extended by four times.
