Item Scope The categories of pumps dealt with are single and multi-stage versions of radial-flow@ mixed-flow and axial-flow pumps. These three categories of pumps are identified by the nature of the flow through the impeller@ see Sketch 2.1. Radial-flow and mixed-flow pumps are commonly classed as centrifugal pumps. The Item covers the pumping of clean@ single-phase liquids only but it should be noted that rotodynamic pumps are available for handling slurries@ sewage and other liquids containing solids or fibrous materials. Further information on this is given in Derivations 34 and 40 (Section 8).
