When selecting a pump it is important to choose the correct model based on application, required flow rate, liquid being pumped and many other criteria.
For some applications either an AODD or a drum pump could be used. For example, an AODD pump can be used for pumping from drums or IBCs, likewise a hand-held drum pump could be used for emptying sumps or drains.
