Hydropulper Leakage Eliminated by DualPac® 2211 Packing!


Chesterton products – Chesterton DualPac® Packing Technology




The gland of a recycle hydropulper can’t be adjusted while running, and therefore maintenance requires full shutdown. The packing in use was leaking excessively and required maintenance often, therefore the plant was losing significant resources and time in restarts. Chesterton recommended five rings of DualPac® 2211 Packing be installed, and the customer experienced longer packing life and less shutdowns.
