Hydrofoil Impeller

High efficiency impellers designed to maximize fluid flow and minimize shear rate.

3 or 4 tapering twisted blades, cambered and sometimes provided with rounded leading edges.

The blade angle at the tip is lower than that at the hub. Resultant flow is streamlined. Vertices around the impeller are lower. Lower power number than PBT.

The solidity ratio is the ratio of the total blade area to a circle circumscribing the impeller.

Low solidity ratio – Liquid blending and solid suspensions.

Higher solidity ratio – Axial flow patterns as the viscosity increases.  In gas-liquid dispersions wide blades provide an effective area of preventing bypass of gas through the impeller hub.
