Anchor Impeller

The shape of the impeller resembles that of the anchor, which generally consists of two blades arranged parallel to the shaft. The anchor impeller generally produces the tangential flow with low shearing forces. These agitators also extend and spread throughout the vessel such that there is very less clearance between the blades and the walls of the vessel. Its primary function is to decrease the thickness of the strongly viscous boundary layer that clings to the vessel wall, enhancing the efficiency of heat exchange.
