Some impellers will require stabilizer fins as shown on the
left. If you have multiple impeller assemblies but only
one set with stabilizers, the set with the stabilizers should
be the set closest to the bottom of the tank (check your
approval drawing to be sure). Make sure the blades are
fastened to the hubs with the stabilizers side down.

Cleveland Mixer offers several different options for mixing impellers. The design of the impeller is typically
based on the process specifications. Different types of mixing and different levels of agitation require
different flow patterns and those flow patterns are created by the style of the impeller blades. The size
and speed of the impeller along with the pitch of the blades will dictate the amount of power needed
to turn them. The mixing power is a combination of the motor and gearbox ratings.
Most mixers are designed specifically to a single process. Cleveland Mixer does not recommend altering
the process or the design of the mixer without first consulting the factory. Increasing the viscosity of the
process media or increasing the output RPM's are common causes for impeller damage and overload
failure.
The most common impeller designs provided by Cleveland Mixer:
1.
Hydrofoil
Impellers are axial thrust-giving elements. These elements give a very high degree of swirling
in the vessel. The flow pattern generated in the fluid resembles a helix.
2. Axial flow turbines impose essentially bulk motion, and are used on homogenization processes, in
which increased fluid volumetric flow rate is important.
3. Radial flow turbines impose essentially shear stress to the fluid, and are used, for example, to mix
immiscible liquids or in general when there is a deformable interface to break. Another application of
radial flow impellers are the mixing of very viscous fluids.
