Super Low Shear Sentinel Radial Flow Impeller (SLS)
Low shear applications where fluid movement is required to suspend solids or blend fluids. Appropriate for processes with products sensitive to shear and requiring uniform flow velocities.
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.
