Redura® Rod Sealing Systems

Redura® Rod Packing Case


Packings are typically subject to a combination of static and dynamic pressure components. The two pressure components differ considerably in terms of their influence on the sealing system’s behavior:

  • Dynamic pressure component results in a high degree of wear, failure by fracture or creep.
  • Static pressure difference is the primary load parameter influencing the leakage rate.


The distribution of the two pressure components among various sealing elements is used to optimize sealing Systems:

  • Pressure relieved or sealing systems with defined wear limit in the vicinity of the compression chamber to buffer the dynamic pressure difference.
  • Subsequent gastight sealing elements are used to handle the static pressure.


Redura® Piston Sealing Systems

Double Acting Piston


Heterogeneous sealing system designs assure perfect sealing for every compression mode:

  • Double acting
  • Single acting
  • Dual acting


The respective pressure components have a major influence on the design of an efficient piston sealing system.The importance of the different pressure components and load conditions has led to the development of heterogeneous sealing systems to provide optimal sealing performance and lowest life cycle costs.Redura® piston sealing systems consist of an elaborate combination of different piston rings and rider rings. The meticulous combination based on the heterogeneous system approach allows each ring to fully deploy its optimum sealing efficiency while reducing wear to a minimum.
