The patented rotor-stator design was optimized with CFD and gives the pump an unrivalled energetic efficiency. “The energy consumption is 40 % to 50 % lower compared to other high-shear pumps”, so an information of the manufacturer. “This high efficiency does not only result in a lower energy bill for every hour the pump is in operation, but also reduces the initial investment. The high-shear pump can be fitted with a smaller motor and the possible frequency convertor is also smaller and cheaper. The optimized flow through the rotor-stator also results in a very quiet operation.”
The high-shear pumps are based on the well-established Packo FP pumps and they share consequently all their valued unique advantages. All the options of the FP pumps are also available on the high-shear pumps and they have almost all spares in common (motors and seals are normalized).
The high-shear pumps (SFP) are plug-and-play mixing units that combine the mixing and pumping function in one machine, hence saving maintenance and floor space. They have pumping capacities up to 200 m³/h and up to 80 m differential pressure.
These features, together with the hygienic design, make the Packo high-shear pumps the favorite in dairy, ice cream, prepared food, beverage, bakery, marmalade and similar industries. Where static mixers, dynamic mixers and agitators can give satisfactory results for simple duties such as blending liquids of similar viscosity and density, the high-shear pumps can reduce mixing times up to 95% in processes where stable emulsions are needed, particle size has to be reduced or texture agents (e.g. xanthan, alginate, pectin, carboxymethyl cellulose, carob, gelatin,…) have to be activated.
Thanks to the recently elevated shear rates of up to 95.000 s-1, the shear-pumps are even suitable for processes where traditionally a homogenizer was needed. Thanks to this ultra-high shear values, the Packo high-shear pump gives enough mechanical work to the pumped liquid to transform yoghurt into drinking yoghurt.
