High-shear impellers convert the majority of the energy of the motor to shear force. They excel at quickly breaking down solids and producing a fine grind. MixerDirect uses three grades for its high-shear blades: the HFD which includes vanes for increased pumping, allowing it to do higher viscosities, the DBL which is a standard design used in the paint industry for many years, and the USB, a brand-new design to get even more shear out of a single high-speed impeller blade.
Stiffening plates can be used in conjunction with dispersion blades to increase blade life. Our bolt-on hubs, weld-on hubs, and blade adapter shaft allow for easy installment of all high shear dispersion blades.
