Trapez-Pack®

Uniform distribution of compression and resulting sealing forces

This decisive modification of packing geometry substantially improves lifetime and sealability of a state of the art pump and valve packing.

Uniform distribution of compression and resulting sealing forces.

Trapez-Pack Advantage

  • The braided trapezoid cross section forms into a perfect square shape during installation
  • Even pressure in all directions inside the stuffing box
  • No OD leakage due to significantly improved k - factor
  • No excessive compression along the shaft therefore reduced friction and heat generation
  • Reduced wear of shaft and packing
  • Packing rings do not rotate with the shaft
  • Reduced run-in procedure and minimized readjustment required.
  • Optimized efficiency and longer lifetime

Packing bent to a ring.

The Square packing profile deforms uncontrolled.

Trapez-Pack places itself evenly around the shaft.
