WitrynaR08 is generally only used for impellers. Anti Thermal Breakdown Rubber (ATB) is a soft natural rubber based on R26, but with improved thermal conductivity. It is intended for use as a liner material in slurry pumping applications where high impeller peripheral speeds are required. R26 is a black, soft natural rubber. WitrynaAmong other uses, they are used in water jets to power high speed boats. Because impellers do not have large blades to turn, they can spin at much higher speeds than propellers. The water forced through the …
