Sharpe HYFLO hydrofoil mixing impellers feature 4 blades with a narrow, low-pitch section at the tip and a wider, higher-pitch section near the hub. The blades are welded directly to a split hub that can be attached anywhere on a shaft without a keyway. Suitable for new equipment or as retrofits on existing agitators, the impellers can be made from Type 316 stainless steel, titanium or other alloys in 3- to 210-in. diameter sizes.
