Propeller stirring rotors
For various applications
The propeller is a well-known stirring rotor that is widely used for low viscosity fluids or suspensions. Typical for propellers are three rounded blades and the mainly axial flow pattern. This effect can be increased by using a guide ring.
Types of mixing
Low viscosity fluids
Medium to high viscosity fluids
Low (80 - 250 rpm)
Medium (400 - 1.500 rpm)
High (600 - 3000 rpm)
Flow direction depending on the blade angle
1.4404 AISI 316L
1.4571 AISI 316Ti
1.4602 Hastelloy® C22
Recommended stirrer size in relation to the container diameter
The application area of a propeller is versatile. It is suitable for homogenising low viscosity liquids or suspensions and provides a proper heat exchange. The flow is directed from the bottom of the container to the walls and up to the top. The stirring medium accelerates downwards at the propeller head.
