Redura® piston sealing systems

As a compressor OEM with more than 170 years of experience, Burckhardt Compression has been setting standards for piston packings and packing rings for decades. Patented designs developed in-house and extensive material research are the perfect recipe for unique high-performance piston sealing systems. This vast in-house tribology and material know-how forms the basis for the comprehensive product line Redura® for rings and packings.

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.

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.

With Redura® Burckhardt Compression provides a comprehensive product line of rings & packings for reciprocating compressors. It stands for reliable, durable and advanced sealing elements. The product line includes standard rings & packings as well as specifically in-house developed, designed and patented products. Redura® rings & packings are characterized by
- Longest MTBO (mean time between overhaul) at lowest leakage
- Highest availability
- Lowest life cycle costs
