What's New?

  • Addition of Purpose and Scope
  • Updated text and figures to clarify or improve existing material
  • Reorganization of standard sections
  • Addition of preferred units (metric and US customary) to nomenclature for primary symbols
  • Update to intake features that require a physical model study
  • Appendix added to provided general information regarding sediment and debris issues at intakes
  • Significant revision to the can pump section
  • Improved guidance on the use of FSI



Scope of Standard:  
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.  This technically advanced standard discusses the proper design for:

  • Rectangular intakes
  • Formed suction intakes
  • Circular pump stations
  • Trench-type intakes for clear liquids and for solids-bearing liquids
  • Tanks – pump suction
  • Can vertical turbine pump intakes
  • Unconfined intakes
  • Circular plan wet pit for solids-bearing liquids


What You Will Learn/Overall Benefits:
 

  • How to configure a functional pumping facility taking into consideration pump geometry and size of inlet connection to ensure uniform flow of liquid into eye of impeller for efficient, reliable operations with less vibration 
  • Understand remedial measures for problem intakes


Applicable Markets: Water and wastewater, process service, petrochemical service and other industries that funnel water and other liquids through intake connections to a pump.
