DualPac® 2211 Severe Slurry Packing
Innovating Packing Technology

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Combining Two Complementary Materials in One Packing​​

Chesterton's new DualPac​®​​ Tech​nology combines the benefits of PTFE and Aramid fibers to create an entirely new level of packing reliability.  Individually these fibers have their drawbacks, but together they offer advanced levels of performance:

  • The low friction and high sealability of PTFE without the consolidation and extrusion
  • The strength​ and resiliency of aramids without the shaft wear
  • Fewer gland adjustments translates to longer life

​DualPac Success Stories

Case Study: Increased Reliability for Cyanide Pulp Pump
A gold mine sealing a cyanide pulp with 60% solids was running through packing every 3-5 days.  

After four rings of DualPac 2211 were installed in 4 pumps​​​​​​

  • Mean Time Between Failure improved to 25-35 days
  • Packing savings: Nearly $800/month
  • Sleeve savings: Over $1,100/month
  • Total annual savings: $23,000+/year

Case Study: Trouble-Free Performance for Gypsum Slurry Sealing​

In a fertilizer mineral processing operation, attempts to seal abrasive gypsum slurry were difficult. Packing and shaft required replacement every few days.  Gypsum material entered the stuffing box and caused pump to leak.

Five rings of DualPac 2211​ were installed, resulting in:

  • 28+ days of trouble-free performance
  • Labor savings: $1,000/month
  • Product loss savings: $4,200+/month
  • Total annual savings: Nearly $70,000/year
