Abstract

A system for pumping or mixing a fluid using a rotating pumping or mixing element and various other components for use in a pumping or mixing system are disclosed.

Claims

exact text as granted — not AI-modified
1 . A mixing apparatus comprising a container having a wall extending in a vertical direction and including an interior compartment for receiving a fluid, a shaft external to the interior compartment and adapted for causing agitation of the fluid in connection with a mixer positioned within the interior compartment of the container, and a first motive device adapted for moving the shaft in the vertical direction. 
     
     
         2 . The apparatus of  claim 1 , wherein the container comprises a flexible bag. 
     
     
         3 . The apparatus of  claim 1 , wherein the shaft is positioned at least partially outside of the perimeter of the container, and projects into a portion of the container contacting the interior compartment. 
     
     
         4 . The apparatus of  claim 1 , wherein the shaft is connected to a second motive device for rotating the shaft relative to the container. 
     
     
         5 . The apparatus of  claim 1 , wherein the mixer is adapted for moving in the vertical direction relative to the container. 
     
     
         6 . The apparatus of  claim 1 , wherein the container includes a cavity for receiving the shaft. 
     
     
         7 . A mixing apparatus comprising a container having a wall extending in a vertical direction and including an interior compartment for receiving a fluid, a shaft external to the interior compartment and adapted for causing agitation of the fluid in connection with a mixer positioned within the interior compartment of the container, and means for moving the shaft in the vertical direction. 
     
     
         8 . The mixing apparatus of  claim 7 , wherein the means for moving comprises a linear actuator. 
     
     
         9 . The apparatus of  claim 7 , wherein the container comprises a flexible bag. 
     
     
         10 . The apparatus of  claim 7 , wherein the shaft is positioned at least partially outside of the perimeter of the container, and projects into a portion of the container contacting the interior compartment. 
     
     
         11 . The apparatus of  claim 7 , wherein the shaft is connected to a second motive device for rotating the shaft relative to the container. 
     
     
         12 . The apparatus of  claim 7 , wherein the mixer is adapted for moving in the vertical direction relative to the container. 
     
     
         13 . The apparatus of  claim 7 , wherein the container includes a cavity for receiving the shaft. 
     
     
         14 . A mixing apparatus comprising:
 a container having a wall extending in a vertical direction and including an interior compartment for receiving a fluid;   a mixer positioned within the interior compartment of the container;   a shaft external to the interior compartment and adapted for causing movement of the mixer; and   a first motive device adapted for moving the shaft in the vertical direction.   
     
     
         15 . The apparatus of  claim 14 , wherein the container comprises a flexible bag. 
     
     
         16 . The apparatus of  claim 14 , wherein the shaft is positioned at least partially outside of the perimeter of the container, and projects into a portion of the container contacting the interior compartment. 
     
     
         17 . The apparatus of  claim 14 , wherein the shaft is connected to a second motive device for rotating the shaft relative to the container. 
     
     
         18 . The apparatus of  claim 14 , wherein the mixer is adapted for moving in the vertical direction relative to the container. 
     
     
         19 . The apparatus of  claim 14 , wherein the container includes a cavity for receiving the shaft.
