Case studies

Sealing applications in practice

Industry: Pulp and Paper
Maschine: High-Pressure Feeder
Industry: Pulp and paper
After only 7 months, a graphite packing failed due to excessive extrusion. One sleeve was damaged. Causing costs: 5.000 € / 6.000 $.
The feeder was repacked with a Trapez-Pack®30. It is now 12 month in service and still running.

Hochreine Kohlefaser

Industry: Chemical 
Machine: Dryer 
Conditions on a shaft of low speed (6 rpm), high pressure (15 bar) and high temperature (250 °C ), a package lasted 6 months. Repackaging was a costly affair each time and brought downtime costs in addition to product loss. As an improvement, the customer chose our TP55, which has already lasted 24 months.

Industry: Food
Machine: Isegen rotary valve
Dry PTFE packing with 4 rings 12.7 mm on a 30 mm shaft at low pressure (1 bar) and room temperature. The service life was mostly only 2 weeks and ended with uncontrollable leakage. The shaft sleeve used had to be replaced after 12 months. Our TP619 is now in use and has lasted 6 months so far.
