Testingese characteristics are usually determined on the basis of tests performed by the manufacturer during the development stage of a given unit. However, to be of real value to a pump user, such tests must be carried out correctly. Otherwise, the pump user my be confronted with very unpleasant surprises.

Pump Performance at Reduced NPSHue at a given flow rate is needed. Rarely does a pump operate under constant conditions. In practice, it usually operates over a wide spectrum of heads, flow rates, and available NPSH values. This may impose more requirements on a pump than simply operating satisfactorily under a given NPSH.

Book 1996es specific examples on how to modify pumpperformance for increased efficiency and better quality control,which turn into long-term cost savings. Some basic theory is includedto give the reader greater understanding of the problems beingencountered and attacked.
