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.
