WitrynaAccording to Brümmer (2012), the tip speed commonly ranges between 20 and 40 m/s for unsynchronized twin-screw expanders and between 60 and 120 m/s for synchronized ones. Much lower values are typically reached for piston and scroll machines. The expander displacement is related to the rotor diameter. 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.
