Rotodynamic Pumps for Hydraulic Performance Acceptance Tests (ANSI/HI 14.6 - secure PDF)

ANSI/HI Standard 14.6 is intended to be used for pump acceptance testing at pump test facilities, such as manufacturers’ pump test facilities or laboratories only. Industry experience shows that it is very difficult to perform measurements accurate enough to satisfy the acceptance requirements in this standard when testing is performed in the field.

Information in the standard may be applied to pumps of any size and to any pumped liquids behaving as clear water.

ANSI/HI 14.6-2011 includes six (6) acceptance grades instead of two (2) that were included in the 2000 versions. Tolerance bands have been developed that will be of interest to those concerned with energy efficiency. Acceptance grades with bilateral tolerances and acceptance grades with unilateral tolerances are defined. Default acceptance grades based on the purchaser’s application are available to guide the pump community (used when there is no specific test acceptance grade in the contract document). The standard contains tolerances for pumps with low horsepower input.

The standard features an updated layout of the test arrangement and appendices containing information regarding measuring equipment, string tests, and discrete test parameters. New graphics and content provide readers with insight into NPSH testing. In addition, it contains special test techniques related to model testing to predict performance of pumps to large to test by conventional means.
