New sealing system by Burckhardt Compressions

The Redura oil sealing system

The Redura oil sealing system

In a reciprocating compressor, sealing systems on the piston rod keep the gas within the compression chamber and ensure that the crankcase oil remains in the crankcase. In general, oil sealing systems are faced with large amounts of oil splash from the crank gear, leading to increased oil leakage. Heterogeneously designed Redura® Oil Sealing Systems consist of an elaborate combination of different ring types, each designed to execute complimentary functions in order to achieve longest MTBO (mean time between overhaul) at lowest leakage rates. The optimized ring design allows the Redura® Oil Sealing System to fulfill the requirements of “dynamic tightness”.
The highlight of Burckhardt Compressions Redura® Oil Sealing Systems, as a part of the heterogeneously designed system, is its new, patented high performance hybrid oil wiper element. With its razor blade technology, a thin bronze blade is accommodated within a non-metallic retainer for precise and gentle oil removal. Designed for universal use the hybrid ring represents lower surface pressure compared to pure metallic versions, which results in longest MTBO.
