The new, efficient high shear mixing method is based on the proven EHEDG certified Packo pump series FP2 with open impeller and series FP3 with closed impeller. The Packo shear mixer pump is mainly used for in-line mixing, homogenisation and dispergation applications. The shear is generated between the rotor and an innovative and optimized perforated stator (patented). The final goal is to achieve a homogeneous solution of two liquids with high difference in viscosity and or density and to obtain a significant particle size reduction for emulsions and particles leading to a more stable final product.
