WebImpeller flow designs can take on three distinct types: axial, radial, and mixed. Because centrifugal pumps are also classified in this manner, the impeller selection depends upon matching the pump's flow characteristic to that of the impeller. Axial flow impellers move media parallel to the impeller. WebDisk - Impellers with disks are used to create a more uniform radial flow pattern and when you need to prevent gases from rising along the shaft of the mixer. Open - The right impeller below has a completely open space between each blade that allows for easy CIP, but provides less power than disk impellers.
