Fluid mixing systems with adjustable mixing element

A fluid mixing system comprising:

• a support housing having an interior surface bounding a chamber;
• an impeller disposed within the chamber;
• a drive shaft coupled with the impeller such that rotation of the drive shaft facilitates rotation of the impeller;
• a drive motor assembly coupled with the drive shaft and being adapted to rotate the drive shaft;
• an adjustable arm assembly mounted on the support housing and coupled with the drive motor assembly for providing three-dimensional movement to the impeller, the arm assembly comprising:
• a lower base coupled to the support housing, an upper base mounted on the lower base by a first swivel joint for rotation around a first axis, and
• a first arm having a first end and an opposing second end, the first end of the first arm coupled to the upper base by a second swivel joint for rotation around a second axis, the second axis being orthogonal to the first axis.
