PARSIPPANY, NJ - The Hydraulic Institute (HI) has released a 2010 update of ANSI/HI 1.4 - 2010, American National Standard for Rotodynamic (Centrifugal) Pumps for Manuals Describing Installation, Operation and Maintenance. The new edition represents a major revision of the original 1999 release. ANSI/HI 1.4 - 2010 provides significantly more content and includes additional new and updated graphics.

According to Gregg Romanyshyn, HI Technical Director, “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. 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.” ANSI/HI 1.4 - 2010 is immediately available through the HI eStore at

The extensive content enhancements cover a range of topics: safety precautions including 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 including rigging and lifting instructions, unpacking instructions, storage environment and moisture protection, and specific requirements for short-term and long-term storage; new product descriptions covering configuration and nomenclature; new installation and site preparation information including site location criteria, seismic analysis of foundation, base-plate leveling and grouting, impeller clearance, motor selection, electrical conduit and boxes, and updated control, monitoring and alarm equipment; operation procedures covering rotation check information, start-up checklist, valve settings, water hammer, and vibrations causes; maintenance directions; troubleshooting; classification of pump type displayed with cross-sectional drawings; and certification.
