The Pitch Blade Turbine impeller is one of the most widely used impellers and one of the oldest designs of the mixing industry. The design of the PBT impeller provides a combination of both radial and axial flow, generates higher shear levels for reactions, and provides excellent mixing ability while providing easy cleanup. Because of the simple design, it is also very cost effective in large applications and higher viscosity applications. While useful in most applications, this design excels in aggressive mixing requiring high power input per volume as well as flow. Geometry is industry standard with a blade angle of 45 degrees.
