The ChemineerTM P-4 impeller is a cost effective impeller in both turbulent and laminar flow, and solids suspension. It is also ideal for applications where the viscosity changes over a wide range causing the flow regime to vary between turbulent and laminar flow.

The P-4 Impeller's axial flow design is suitable for wide changes in process viscosity and is efficient for immiscible blending applications where shear and pumping is required. It is also excellent for solids incorporation from the liquid surface.
