Radial Vane Impeller
Definition - What does Radial Vane Impeller mean?
A radial vane impeller is a type of rotor used to increase or decrease the pressure and flow of a liquid. It is unique from other impeller types due to its diverging fans from its center point, which operate mechanically to generate energy. The number of fans (divergence) can be manipulated to generate the required pump flow energy.
Corrosionpedia explains Radial Vane Impeller
Radial vane impellers are used primarily in radial vane pumps, which are generally found in applications requiring optimized performance at low specific speeds. Such applications have a high relative pressure difference between the pump's origin and destination locations. A smaller diameter radial vane impeller wastes less energy and vice versa.
Frequent impeller inspections should be performed to check for corrosion because the frequent rotation and passage of fluid makes radial vane impellers prone to severe erosion corrosion.
