Full Description Scope of Standard: ANSI/HI 14.6 covers hydraulic performance tests for acceptance of rotodynamic pumps. Standards are for used for pump acceptance testing at manufacturer pump test facilities or laboratories only. Industry experience shows that it is very difficult to perform measurements accurately enough to satisfy acceptance requirements in this standard when testing is performed in the field. Information in this standard may be applied to pumps of any size and to any pumped liquids behaving as clean cold water. Rotodynamic pump designs addressed: Centrifugal Mixed flow Axial flow
