ShearPro Mixing Tool Set for SP1004

Customize Item


Customize your ShearPro SP1004 capabilities with additional mixing tools suited to your process needs. Choose from ExoShear, Pulsor, and UltraShear rotor stators to accomplish a variety of mixing requirements. All ShearPro mixing tools are 316SS.

The ExoShear mixing tools are characterized by their straight, four-bladed rotor and the single ring stator with holes of varying diameter. The rotor is designed to maximize the pumping capacity of the mixing tool. Available in 3 stages of shear, the ExoShear 1 provides the coarsest blending by allowing very large particles to enter the mixing tool and process through the mixers. The ExoShear 2 is an intermediate option with a larger number of smaller diameter holes in the stator, providing more shear than the ExoShear 1. The ExoShear 3 provides the highest shear of the three ExoShear tools, by using a larger number of smaller diameter holes to reduce particles in the process. These tools are most commonly used for recirculating processes, where high flow rates are required due to the larger batch sizes or when initial particle sizes are too larger for other mixing tools.

The Pulsor mixing tools are characterized by their sweeping impeller blades, similar to ones used in centrifugal pumps. These rotors produce high flow rates but their mixing energy is reduced by converting some of the total energy from mixing to the pumping action. The Pulsor is available in 2 shear options, with the Pulsor 1 providing moderate shear, and the Pulsor 2 providing higher shear.

The UltraShear mixing tools are characterized by their fine rings of teeth located on both the rotor and stator. The UltraShear tools provide the most mixing energy but the lowest pumping capacity. Available in 4 stages, with the UltraShear 1 allowing the largest particles through and UltraShear 4 with the smallest particle size, these tools are the most effective at achieving fine to ultra-fine dispersions. Careful consideration about over-shearing the product should be used when selecting an UltraShear, as product can be damaged with such high levels of shear.
