WORKING

The Cowles / Sawblade design of this impeller provides mixing by generating high shear levels. The Cowles / Sawblade is suggested for use in wetting out powders, dispersing fine solids, breaking up agglomerations (clumps) and creating emulsions. This impeller can be fabricated to fit almost any shaft diameter and comes standard in 316 Stainless Steel, but we can build this design in any alloy or even in composite material. Hardened coatings are also available for greater wear resistance. Our standard STX follows industry typical blade geometries, but custom variations are also available as well.

FEATURES

• Standard size bore for 1-5/8" diameter up to 6" diameter is 1/2" w/keyway.
• Standard size bore for 8" diameter and up is 5/8".
• Other bore sizes available
• "Odd" sized blades can be made. (E.G. 7", 13", 14-1/2", Etc.)
• Blades made with 1/2" bore; adapters available for smaller shafts.
• Blades can be furnished with hubs for mounting on smooth shafts.

K BLADE (Design A)

Design A dispersion blades have performance matching the Hockmeyer "K" design. Feature a square tooth pattern and spaces between the teeth. Versatile blades differing only slightly from the F style. They require less horsepower and are applicable in operations where the available horsepower is borderline for batch size. (As the blade size decreases 4" or less, the design of the "A" blade changes slightly due to the manufacturing process.)

F BLADE (Design B)

Design B dispersion blades have performance matching the Hockmeyer "F" design. Use for pumping and mass flow, cutting, and agglomerate reduction. The most popular and versatile blades. The uniform teeth accelerate pigment particles and break up agglomerates. High shear is quickly achieved with turbulent flow.

GF BLADE (Design C)

Design C dispersion blades have performance matching the Hockmeyer "G" design. Best utilized for high speed blending with medium shear. Ideal for heavy body and thixotropic liquids.
This High-vaned blade is designed for turbulent flow to provide fast blending and agitation. It will disperse pigments or flatting agents rapidly in high viscosity or thixotropic systems with minimum heat buildup.
