Sealless Rotodynamic Pumps for Nomenclature, Definitions, Application, Operation, and Test (ANSI/HI 5.1-5.6-2016)
Scope: ANSI/HI 5.1-5.6 offers a basic educational overview on sealless rotodynamic pumps including design and application considerations related to the selection of the right pump for a specific industry use, pump operating and maintenance procedures as well as different types of tests that can be conducted on pumps to ensure their performance.
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: 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 - 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)
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 Submersible Pumps: for Hydraulic Performance, Hydrostatic Pressure, Mechanical and Electrical Acceptance Tests (ANSI/HI 11.6-2017)
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.
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.
