Claim 0:
1. A portable pump assembly insertable through a first opening in a container to mix fluid in the container, the pump assembly comprising:
a screw mixing shaft which, when inserted and connected to the container, is rotatable with respect to the container, the pump assembly having first and second opposing end portions each suitable for passage of the fluid therethrough, the first end portion including a first pump-opening for receiving the fluid into the pump assembly and the second end portion including at least a second pump opening for emitting the fluid from the pump assembly to within the same container, wherein the mixing shaft positioned within the pump assembly to act as a screw conveyor, the pump assembly operable to circulate the fluid within the container while the mixing shaft is rotating wherein, when at least the first end portion of the pump assembly is inserted into a non-homogeneous portion of the fluid and the mixing shaft undergoes rotation with respect to the container, part of the non-homogeneous portion of the fluid enters the pump assembly through the first pump opening, exits the pump assembly through the second pump opening and travels along a surface of the pump assembly to effect mixing of fluid passing through the assembly, thereby improving homogeneity of the fluid;
a connection interface to provide engagement between a motor and the pump assembly to rotate the mixing shaft with the motor, the connection interface including a body section having a surface for connection to the pump assembly and providing a sealing engagement between the container and the pump assembly to seal the first opening in the container during mixing; and
a collar fixedly positionable for connection about the second end portion of the pump assembly to extend away from the pump assembly, the collar having a surface along a collar opening sized and shaped to receive the surface of the body section for an engagement that affixes the body section to the pump assembly.
