PL04 - Understanding the Effects of Selecting a Pump Performance Test Acceptance Grades
Abstract
There are good reasons for requiring the tightest test acceptance tolerances. That is why they are listed in industry accepted pump testing standards, ANSI/HI 14.6, ANSI/HI 11.6 and ISO 9906. There are also applications where selection of the more stringent grade is not necessary to insure the pump will operate satisfactorily in the process. The user or specifier should evaluate all grades available and make an informed decision selecting the correct grade for their application, delivery requirements and cost targets. This paper briefly highlights the importance of selection of proper acceptance grade for pump performance testing. In most cases there is plenty of logic in the selection of the grade and how it is applied. However, the impact on the cost and delivery of that decision is not always clearly understood. Application of the tightest tolerances will require more work by the manufacturer which will typically extend the delivery date and increase the cost to accommodate the extra effort to insure the pumps comply. Less stringent grades will require less work and shorten the time to manufacture and test. The paper will present the acceptance grades available and the tradeoffs of specifying each grade.
