Rotodynamic Pumps Guideline for NPSH Margin (ANSI/HI 9.6.1-2017)
Scope: ANSI/HI 9.6.1 serves as a guideline for NPSH margin for rotodynamic pumps with absorbed power levels up to 5300 hp and impeller tip speeds less than 130 feet per second. The purpose of this guideline is to establish recommended net positive suction head available (NPSHA) above the published NPSH required (NPSHR) that will lead to acceptable pump performance and service life.
Rotodynamic pumps – Guideline for Operating Regions (ANSI/HI 9.6.3-2017)
Scope: ANSI/HI 9.6.3 discusses the effects of operating a rotodynamic pump continuously or for a long duration at rates of flow greater than or less than the pump’s best efficiency point (BEP) rate of flow. These effects influence the power consumption and life of pump components and, therefore, determining the preferred/allowable operating range of flows is essential to reliable, efficient pump operation.
Rotodynamic Pumps for Vibration Measurement and Allowable Values (ANSI/HI 9.6.4-2016)
Scope: ANSI/HI 9.6.4 pertains to evaluation of vibration when the vibration measurements are made on stationary parts associated with bearings (bearing housings) of rotodynamic pumps. It provides specific maximum allowable vibration values measured on bearing housings of rotodynamic pumps in field and factory test environments. This standard applies to the evaluation of vibration on rotodynamic pump applications absorbing more than 2 kW (3 hp).
Rotodynamic Pumps Guideline for Condition Monitoring (ANSI/HI 9.6.5-2016)
Scope: ANSI/HI 9.6.5 offers pump monitoring and failure detection techniques for rotodynamic pumps (both sealed and sealless designs).
Rotodynamic Pumps for Pump Piping (ANSI/HI 9.6.6-2016)
Scope: ANSI/HI 9.6.6 details pump piping requirements for rotodynamic pumps and effects of inlet/outlet piping on pump performance. Standards are applicable to all piping downstream and upstream from the pump but not when entering tank, vessel or intake structure.
Rotodynamic Pumps – Guideline for Dynamics of Pumping Machinery (ANSI/HI 9.6.8-2014)
Scope: 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)
Scope: ANSI/HI 9.8 applies to the design of new intakes as well as the modification of existing designs used with rotodynamic pumps. It outlines standard intake designs based on certain criteria, beyond which requires a physical model study to be in compliance with the standard.
Rotodynamic Centrifugal Slurry Pumps (ANSI/HI 12.1-12.6-2016)
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.
ANSI/HI 1.1-1.2 - 2008

Scope: ANSI/HI 14.1-14.2 provides types, nomenclature, and definitions of rotodynamic pumps with radial, mixed flow, and axial flow impellers, as well as regenerative turbine, Pitot tube, vertical diffuser, submersible motor deep-well and shortset pumps, commonly defined as vertically suspended rotor and vertical overhung impeller types (that may be driven by vertical electric motors or horizontal engines with right-angle gears) of all industrial/commercial types.

Rotodynamic Pumps for Design and Application (ANSI/HI 14.3-2019)
Scope: The purpose of this standard is to provide guidance and recommendations for the general application and design of rotodynamic pumps. This standard provides accepted methods for the evaluation of the hydraulic performance and design of all related and supporting equipment.
Rotodynamic Pumps for Installation, Operation, and Maintenance (ANSI/HI 14.4-2018)
Scope: This standard applies to IOM manuals for all rotodynamic pumps For additional instructions on sealless rotodynamic pumps, see ANSI/HI 5.1-5.6 Sealless Rotodynamic Pumps for Nomenclature, Definitions, Application, Operation, and Test For additional information on rotodynamic pumps types, see ANSI/HI 14.1-14.2 Rotodynamic Pump for Nomenclature and Definitions.
Rotodynamic Pumps for Hydraulic Performance Acceptance Tests (ANSI/HI 14.6-2016)
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.
