scope:

This standard covers hydraulic performance tests for acceptance of rotodynamic pumps (centrifugal, mixed flow, and axial flow pumps), in this document referred to as pumps.

ANSI/HI Standard 14.6 is intended 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 rotodynamic pumps of any size and to any pumped liquids behaving as clear water (see Appendix M.1).

This standard applies to a pump by itself without any fittings. The pump may also be tested with a combination of upstream and/or downstream fittings by prior agreement and agreed on contractually.

There are other pump acceptance test standards for submersible (OH8A and OH8B) and sealless pumps, as defined in their respective documents, that take into account the unique features that those products exhibit. The Hydraulic Institute recommends that the user of this standard consult those respective standards (ANSI/HI 11.6 and ANSI/HI 5.1-5.6 Sealless Rotodynamic Pumps for Nomenclature, Definitions, Design, Application, Operation, and Test) to determine if one of these standards are more appropriate for the products being considered for testing.

Purpose

This standard provides acceptance criteria and uniform procedures for performance, net positive suction head, hydrostatic pressure testing, data recording, and reporting of test results for rotodynamic pumps. It provides acceptance grades that can be specified for various types of applications. It also defines test procedures that will result in consistent and repeatable results. Final acceptance grade selections will be defined in a contractual agreement between the purchaser and manufacturer.
