Super Low Shear Sentinel Radial Flow Impeller (SLS)
The SLS or Super Low Shear Impeller provides minimum fluid shear while maintaining a good blending characteristic in low viscosity applications such as flocculation. The large blade projected height results in a relatively large power number compared to other impellers reducing the necessary impeller speed required for mixing. A lower impeller speed yet larger pumping rate provides good vessel circulation and reduces local velocity gradients which cause damage to sensitive crystallizations and flocculation.
