Folding impellers are most commonly used in mixing applications where access to the vessel is limited, such as with 55 gallon drums. Fusion's folding drum impeller design is essentially a two-bladed, pitch blade turbine impeller design, where the blades fold down against the shaft when not in use. The folding design allows the impeller and shaft to be inserted and retracted through a 2" NPT hole (approximately 2.06”) typically found in drum lids. Fusion's design allows the impeller to slide up the shaft for adjustment. Folded diameter is 2”.
This design provides a combination of both radial and axial flow, generates high shear levels, and provides excellent mixing ability while allowing easy installation and removal.
Fusion's folding drum impellers come standard in 316 Stainless Steel with standard mill finish.
