ANSI/HI Pump Standards are available in both hardcopy and secure PDF formats. Secure PDFs are immediately downloadable and incur no shipping or handling charges. Standards in this format are a single user license and require a one-time authorization using an Adobe-approved plug-in from FileOpen Systems.
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.
Scope: ANSI/HI 2.3-2013 discussions the design and application considerations related to the selection of the right rotodynamic vertical pump for a specific industry use.
Scope: ANSI/HI 2.4 serves as a guide in creating a pump manual so users have complete information on pump installation, operation and maintenance.
Scope: ANSI/HI 9.1-9.5 provides general guidelines on how to measure sound levels and decontaminate returned part pumps for a large variety of positive displacement and kinetic pumps.
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 power levels as high as 5300 hp and impeller tip speeds less than 130 feet per second.
Scope: Excessive loads to pump nozzles can cause misalignment between the driver and pump, physical pump deformation and comprise internal pump condition.
Scope: ANSI/HI 9.6.3 discusses the effects of operating a rotodynamic pump at flow rates greater than or less than the rate of flow at the pump’s best efficiency point (BEP). As these effects influence the power consumption and life of pump components, considering the operating rate of flow is essential to reliable, efficient pump operation.
Scope: ANSI/HI 9.6.4 covers the vibration measurement made on non-rotating parts (bearing housings) of most industrial/commercial centrifugal and vertical pumps.
Scope: ANSI/HI 9.6.5 offers pump monitoring and failure detection techniques for rotodynamic (centrifugal and vertical) pumps, both sealed and sealless designs.
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.
Scope: ANSI/HI 9.67 outlines method for predicting performance of rotodynamic pumps in Newtonian liquids of viscosity greater than water. The standard applies to single and multi-stage rotodynamic (centrifugal and vertical) 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.
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.
These vertical pump standards, developed by the American Society of Mechanical Engineers,are sold through the Hydraulic Institute in secure PDF format.
The purpose of HI Electronic Data Exchange is to define a common industry standard for the electronic exchange of technical data
commonly used to describe pumping equipment. All software applications or systems that adhere to this standard
are able to exchange technical data reliably and efficiently with all other systems that comply with this standard.
