R55 Slurry Pump Rubber Parts Material
Materials technology - R55
To further assist one aspect of pump’s wear performance, the R55™ material has been introduced. R55™ is a premium grade material for use in a high wear application. It is a black natural rubber, of low hardness and is used for pump liners and impellers, as well as cyclones. Superior physical properties give increased cut resistance to hard, sharp particle slurries, resulting in improved wear characteristics. It is particularly suitable for large particle erosive slurry applications such as mill discharge applications. Tests have consistently shown that wear life with R55™ can be increased by as much as 50% over previous materials.
The R55™ material has replaced our previous natural rubber grades such as R08A, R24, R26A, W411 and W413, brought about by progressive improvements in materials technology.
