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 absorbed power levels up to 5300 hp and impeller tip speeds less than 130 feet per second. (More...)
Scope: This standard includes recommendations for assessment of applied nozzle loads for various pump types
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.
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).
Scope: ANSI/HI 9.6.5 offers pump monitoring and failure detection techniques for rotodynamic 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 9.6.7 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.
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.
