Redura® rod sealing systems

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

Burckhardt Compression’s sealing philosophy is based on the operational behavior of gastight friction seals. Packing rings are typically subject to a combination of static and dynamic pressure components. This has led to the design of heterogeneous sealing systems, where pressure breakers buffer the dynamic pressure component in order to enable the subsequent sealing elements to reliably seal the gas compression chamber and minimize the leakage rate, which is influenced by the static pressure. Depending on the required performance, the heterogeneous combination of pressure breakers, support rings and true seal elements is employed to provide ideal sealing performance and longest lifetime.

Burckhardt Compression provides various packing types for every application as well as packing ring designs, from enhanced classical rings to specifically in-house developed and patented rings.

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
