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: 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.
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.
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.
Scope: ANSI/HI 14.6 covers hydraulic performance tests for acceptance of rotodynamic pumps. Standards are for used for pump acceptance testing at manufacturer pump test facilities or laboratories only. Industry experience shows that it is very difficult to perform measurements accurately enough to satisfy acceptance requirements in this standard when testing is performed in the field.
Scope: This standard covers testing of rotodynamic pumps, up to 150 kW (200 hp) establishing minimum testing protocols for verification of pump efficiency conforming to US Department of Energy (DOE) regulations.
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.
