Hydraulic Institute Releases 2010 Update of ANSI/HI Standard 1.4 for Centrifugal Pump Manuals

The Hydraulic Institute (HI) has issued a 2010 revision of ANSI/HI 1.4 – 2010, the American National Standard for Rotodynamic (centrifugal) pumps, which governs the creation of manuals that describe installation, operation, and maintenance.

In a major overhaul of the 1999 edition, ANSI/HI 1.4 – 2010 expands its scope considerably, adding new sections and updated graphics that enhance clarity and usability.

‘This new standard establishes a convention that will provide IOM manuals that are consistent and will help pump users locate IOM information in their vendor manuals quickly and conveniently,’ says Gregg Romanyshyn, HI technical director. ‘The organization of the manuals has been fully harmonized with the organization of the manuals for Rotodynamic (vertical) pumps, as provided in ANSI/HI 2.4 – 2008 that was released previously.’

The standard is now available for purchase at the HI eStore (https://www.estore.Pumps.org) for $70.

Key content additions include:

• Safety Precautions – general safety requirements, specific actions and maintenance suggestions to prevent injury and damage, explosive‑atmosphere safety, prevention of excessive temperatures, explosive moisture buildup, sparks, and leakage.
• Transportation and Storage Requirements – rigging and lifting instructions, unpacking procedures, storage environment and moisture protection, and guidelines for short‑term and long‑term storage.
• New Product Descriptions – updated configuration and nomenclature.
• New Installation and Site Preparation Information – site‑location criteria, seismic analysis of foundations, baseplate leveling and grouting, impeller clearance, motor selection, electrical conduit and boxes, and updated control, monitoring and alarm equipment.
• Operation Procedures – rotation checks, start‑up checklists, valve settings, water‑hammer mitigation, and vibration causes.
• Maintenance Directions, Troubleshooting, Classification of Pump Type – cross‑sectional drawings, and certification details.

The standard was developed by a committee that included representatives from Flowserve Flow Solutions Group, Weir Floway, Inc., Peerless Pump Company, ITT – Industrial Process, Sulzer Pumps (US) Inc., National Pump Company, LLC., Pentair Water, John Crane Inc., and Emerson Motors / US Motors. Romanyshyn noted that ‘the committee recognized the importance of providing their customers with important information organized in a uniform, consistent manner.’
