Rotodynamic Vertical Pumps of Radial, Mixed, and Axial Flow Types for Nomenclature and Definitions (ANSI/HI 2.1-2.2-2014)
Scope: ANSI/HI 2.1-2.2 offers a basic educational overview on rotodynamic vertical pumps providing nomenclature and definitions that apply to different parts of pumps and classifications by configuration and impeller design.
Pumps - General Guidelines (ANSI/HI 9.1-9.5-2015)
Scope: ANSI/HI 9.1-9.5 applies to all industrial/commercial pumps of positive displacement and rotodynamic types. This document covers pump type classifications, materials of construction, airborne sound measurement, and decontamination.
Rotodynamic Pumps Guideline for NPSH Margin (ANSI/HI 9.6.1-2017)
Scope: Today’s higher speed, higher energy density pumps might not achieve acceptable service life without an adequate NPSH Margin that ensures pumps operate without excessive vibration and cavitation. 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 for Assessment of Applied Nozzle Loads (ANSI/HI 9.6.2-2015)
Scope: This standard includes recommendations for assessment of applied nozzle loads for various pump types
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 Effects of LiquidViscosity on Performance (ANSI/HI 9.6.7-2015)
Scope: ANSI/HI 9.6.7 outlines the method for predicting performance of rotodynamic pumps in Newtonian liquids of viscosity greater than water. The standard applies to single and multi-stage rotodynamic pumps having radial impellers ns = 60, (Ns = 3000), handling liquids exhibiting Newtonian behavior, and a kinematic viscosity greater than 1 and less than 4000 centistokes.
Rotodynamic Pumps – Guideline for Dynamics of Pumping Machinery (ANSI/HI 9.6.8-2014)
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: 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 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.
