Blade / Half-Moon Impellers Precise working with an overhead stirrer critically depends on the right choice of stirring tool. These stirring tools differ in the type of flow they cause in the medium, in the speed-dependent field of application and in their design to suit different viscosities. The following applies to all stirring tools: optimum mixing results are achieved if the vessel size and positioning of the stirring tool are perfectly matched. Primary flow direction is tangential These impellers are particularly recommended for applications which require average to high speeds For...
