The Effect Of Design Features On Centrifugal Pump Efficiency
MetadataShow full item record
Charts relating the efficiency of a single stage centrifugal pump to the specific speed were presented at the Texas A&M University Third International Pump Symposium in April 1986 . These charts attempted to resolve some of the basic discrepancies of the original chart published forty years ago, and to introduce a technique for incorporating speed as an indicator of pump size. These charts defined what we believed to be the highest efficiencies that could be achieved provided clearly defined standards of manufacture and specified operating conditions were applied. The previous paper was an attempt to define these constraints as well as to indicate some of the possible penalties that might be incurred if these constraints were not observed. The purpose of this presentation is to present techniques that will permit a determination of the effect on efficiency when derivations from the specified constraints are considered.
