Redura® Rod Sealing Systems Heterogeneous Rod Sealing Systems For best performance Burckhardt Compression’s sealing philosophy is based on the operational behaviour of gastight friction seals. Since as early as 1993 we have been constantly measuring and analysing pressure distributions of dry running packings. Packings are typically subject to a combination of static and dynamic pressure components. Discharge pressure Pressure at the packing inlet B Suction pressure Pressure at the packing outlet The distribution of the two pressure components among various sealing elements is used to optimize...
