Products featured in this case study:
A pulp and paper customer was using a competitor’s packing on an agitator in a chemical application. The packing wore down the sleeve, requiring replacement of both packing and sleeve every three months.
Sleeve Cost: $500 US ($670 AUD) every three months = $2,000 US/year ($2700 AUD/year)
Competitor Packing Cost: $1,000 US/year ($1300 AUD/year)
Labor Cost: $1,600 US/year ($2100 AUD/year)
Total Cost Per Agitator: $4,600 US/year ($6200 AUD/year)
The customer’s goal was to increase continuous service time to support plant cycle and reduce costs.
Five rings of DualPac® 2211 Packing were installed as shown for solids resistance. With the DualPac® 2211 Packing aramid side against the bottom of the stuffing box, resistance to extrusion and solids is achieved with minimal contact between the aramid and the shaft. This unique configuration reduces shaft wear and increases uptime.
The improved packing solution has lasted over six months and sleeve wear is no longer an issue. The customer is extremely pleased.
