Drum pump tubes are assemblies with a rigid intake shaft and an impeller for drawing fluid out of a container. Also called a barrel tube, these tubes attach to a pump motor and fit through the opening of a container to dip into the fluid within. The impeller rotates when driven by a pump motor to move fluid through the shaft and up to the outlet of the pump. Drum pump tubes can replace a damaged tube on an existing drum pump assembly or be paired with a separate motor to create a custom pump assembly. They can also be swapped out to adapt a drum pump for compatibility with different fluids.
