High Vane Impellers
High Vane Impellers are radial flow dispersing impellers supplied through Blade Depot®, a division of Norstone, Inc. The vane geometry directs high volume flow across the entire batch, supporting dispersion and mixing applications where minimal shear is required. Available in 304 stainless steel and additional materials of construction, High Vane Impellers mount on a center hole configuration and operate across a range of speeds for batch processing in coatings, inks, and related industries. Within the Blade Depot® line, High Vane Impellers occupy the minimal shear position, distinguishing them from the high shear designs of High Shear Impellers and Turbine Blades.
Characteristics
High Vane Impellers are defined by the following properties:
- Radial flow pattern. The vane geometry directs flow outward across the entire batch, distinguishing High Vane Impellers from the perimeter shear generation of High Shear Impellers.
- Low to moderate speed range. High Vane Impellers operate at rotational speeds suited to high volume, minimal shear mixing rather than the high speed dispersion of High Shear Impellers.
- Low to medium viscosity fit. The design is suited to low to medium viscosity materials, distinguishing it from the high viscosity applications addressed by High Viscosity Blades.
- 304 stainless steel construction. High Vane Impellers are available in 304 stainless steel, with additional materials of construction available.
- Center hole mounting. The blades mount on a center hole configuration for shaft mounting across a range of batch volumes.
Because High Vane Impellers are generally selected for minimal shear rather than high shear dispersion, they should be compared against High Shear Impellers or Turbine Blades where higher shear is the process requirement.
When High Vane Impellers Are Typically Selected
High Vane Impellers are generally chosen for letdown of coatings requiring uniform dispersion across the entire batch, and for emulsification and homogenization of low to medium viscosity materials. Compared to Turbine Blades, which generate high shear dispersion through radial blade hubs, High Vane Impellers are selected when minimal shear and reduced heat buildup are the priority. Compared to High Shear Impellers, which are built for aggressive high speed dispersion, High Vane Impellers are selected for high volume batch movement rather than maximum shear.
Applications
High Vane Impellers support dispersion and mixing applications across the following use cases:
- Letdown of coatings requiring uniform dispersion across the entire batch
- Emulsification and homogenization of low to medium viscosity materials
- Dispersion of wax, ceramics, and related particles where minimal shear and reduced heat buildup are required
- High volume batch processing across a range of batch sizes, from laboratory to production scale
