The Axial flow impeller for gas/ liquid applications is capable of dispersing gas and controlling flow patterns at significantly higher gas rates than other axial flow impellers. Compared to conventional Rushton type radial flow turbines, the Axial flow impeller for gas/ liquid applications can provide up to 30% greater mass transfer at equal torque and power consumption. Good axial flow patterns from the Axial flow impeller for gas/ liquid applications give good solids suspension and significantly reduce power requirements.
