This is suitable for high viscosity fluids, and advantageous when the wall boundary layer is disturbed and when solids adhere to the wall. It is usually used in large scale and at low speed, and those with baffles can generate a strong turbulent flow.Īnchor impellerThis impeller has a shape similar to an anchor of a ship. This is suitable for low to medium viscosity fluids, and widely used in industries. Pitched paddle impellerThis impeller has blades each in a shape similar to an oar of a small boat. Though it requires high consumption power, it is best characterized by its ability to generate high shear force, as well as the discharge ability and wide application range. This is suitable for low to medium viscosity fluids, gases, and liquids. This is suitable for low to medium viscosity liquids, and energetically advantageous when suspending solid particles in a low viscosity liquid since an axial flow is formed.ĭisk turbine impellerThis impeller has a shape of a disk attached with blades. Propeller impellerThis is the most common impeller.
