Drum pumps are used if the liquid has just to be pumped out of a barrel. The pumps can be inserted directly into the barrel and, using a discharge hose (with a nozzle if this is required) you can transport the liquid to the desired destination.

Various pump units are available with different impeller types and in a range of materials depending on the liquid to be pumped. There are also excentric screw pumps for highly viscous liquids.
