Engineered for new and retrofit installations where tank entry is impractical or too expensive, the Sharpe Folding Blade HYFLO 218 impeller features a hydrofoil-style, 4-blade design; it folds for installation and opens with centrifugal force, locking in place when fully opened. The blade locking mechanism can be accessed from outside the tank for removing the mixer, if necessary. Typical retrofit applications include side entry for large storage tanks or top entry when the tank service has changed, and a new mixer is required.
