Advantages:
These impellers are sometimes called a flat-blade radial turbine and have four or more vertical blades, equally spaced around a disk.
The flow is discharged radially outward to the vessel wall with half the flow directed upward, and half the flow directed downward.
Although they can be used for any type of single- and multiple-phase mixing duty, they are most effective for gas–liquid and liquid–liquid dispersion and provide higher shear and turbulence levels with lower pumping.
With suitable baffles these flows are converted to strong top-to-bottom flows both above and below the impeller.
The new generation of radial turbine is backswept turbine that has six curved blades. The backswept nature of the blades prevents material buildup on the blades and has highest gas dispersing capability available. It is also less susceptible to erosion.
