The article offers information on selecting a centrifugal pump. Definitions are provided for key pump-related terms, including affinity laws, best efficiency head (BEH) and best efficient point (BEP). A centrifugal pump is described as a non-positive displacement and dynamic machine that transfers mechanical energy into pressure. Its performance is also measured by a volume of delivery against the height at which it will lift a column of water, in consideration of its efficiency.
