Rotodynamic Pumps – Guideline for Dynamics of Pumping Machinery (ANSI/HI 9.6.8-2014 - secure PDF)
This guideline describes and recommends the means to appropriately evaluate pumping machinery construction attributes and relevant site characteristics in order to determine the effects of dynamic performance on equipment life and reliability. It describes and recommends various levels of detailed evaluation and validation that are commensurate with the degree of equipment uncertainty and application risk.
Rotodynamic Pumps for Pump Intake Design (ANSI/HI 9.8-2018) - secure PDF
Scope: Ideally, the flow of liquid into any pump should be uniform, steady, and free from swirl and entrained air. Lack of uniformity through inlet connection can result in pumps not operating to optimum design condition and at a lower hydraulic efficiency.
Rotodynamic Submersible Pumps: for Hydraulic Performance, Hydrostatic Pressure, Mechanical and Electrical Acceptance Tests (ANSI/HI 11.6-2017 - secure PDF)
Scope: This standard applies to customer acceptance testing of rotodynamic submersible pumps driven by electric motors, unless otherwise agreed or specified. A submersible pump is defined as a close-coupled pump/motor unit designed to operate submerged in the pumped liquid. This definition includes submersible pumps operating in either a wet-pit or dry-pit environment. Excluded are deep well pumps, progressive cavity pumps and pumps not powered by an electric motor. A standard test measures pump performance from pump inlet to pump outlet and electrical input power. It does not include accessory items, such as outlet elbows, inlet fittings, or valves, unless specified by a contractual agreement. This standard also includes the acceptance criteria for original equipment manufacturer (OEM) factory and permanently installed pump vibration testing.
Rotodynamic Centrifugal Slurry Pumps (ANSI/HI 12.1-12.6-2016 - secure PDF)
Scope: ANSI/HI 12.1–12.6 offers a basic educational overview on rotodynamic centrifugal slurry pumps, design and application considerations related to the selection of the right pump for a specific industry including pump installation as well as operation and maintenance procedures.
Rotodynamic Pumps for Hydraulic Performance Acceptance Tests (ANSI/HI 14.6-2016 - secure PDF)
Scope: This standard covers tests for acceptance of rotodynamic pumps (centrifugal, mixed flow, and axial flow pumps), in this document referred to as pumps.
Rotodynamic Pump Efficiency Prediction (HI 20.3-2015 - secure PDF)
Scope: ANSI/HI 20.3 presents a simplified method to predict normally attainable efficiency levels at the best efficiency point for selected types of rotodynamic pumps when the rate of flow, total head per stage, net positive suction head available (NPSHA), and the service conditions are known.
 Hydraulic Institute Program Guide for HI Energy Rating Program (HI 40.5-2016)
Scope: The scope of pumps included in the Program are limited to pumps identified in the energy conservation standard developed by the US Department of Energy (DOE) and listed in Section of this document (hereinafter referred to as the "guiding standards").
Hydraulic Institute Standard for Methods for Rotodynamic Pump Efficiency Testing (HI 40.6-2014 - Secure PDF) For Historical Reference
Scope: This standard is incorporated by reference in the Uniform Test Procedures for “Pumps” and “Dedicate Purpose Pool Pumps” as outlined in the Department of Energy - Energy Conservation Program ( This standard established minimum testing protocols for testing of rotodynamic pumps for determination of pump efficiency in a uniform manner.
Hydraulic Institute Standard for Methods for Rotodynamic Pump Efficiency Testing (HI 40.6-2016 - Secure PDF)
Scope: HI 40.6 is intended to be used for efficiency testing at pump test facilities or laboratories only. Industry experience shows that it is very difficult to perform measurements accurate enough to satisfy the requirements in this standard when testing is performed in the field. Therefore field-testing is not permitted as a method of efficiency testing per this standard.
Hydraulic Institute Program Guide for Pump Test Laboratory Approval (HI 40.7-2015)
Scope: Participants in the pump test lab approval program include any organization, such as a corporation, research institution, laboratory, etc., whether domestic or international, that have the capability to test pumps and extended products to applicable test standards.
