Rotodynamic Pumps for Pump Intake Design
This standard applies to the design of new intakes as well as the modification of existing designs used with rotodynamic pumps. It outlines standard intake designs based on certain criteria, beyond which requires a physical model study to be in compliance with the standard. Ideally, the flow of liquid into any pump should be uniform, steady, and free from swirl and entrained air. Lack of uniformity at the pump inlet can result in reduced performance, lower efficiency, cavitation, elevated noise and vibration, and other items that result in reduced reliability.
Those involved in the design or use of pumps systems that are clean or include solids bearing liquid with free surface intakes that are rectangular, circular, or suction can types should use this standard. Free surface pump intakes are applicable to all industry segments but are most common in municipal water and wastewater, chemical, oil & gas, power generation, cooling water and cooling towers.
What’s New:
This standard supersedes the ANSI/HI 9.8-2018 edition. Updates in the new edition include:
• Revision to physical model study requirement for closed-bottom suction can pumps
• Improved guidance on pump operating conditions that influence intake design
• Updates and additions to terms and definitions
• Updates to content and figures that clarify or improve existing material
