This course focuses on the hydraulic principles of centrifugal pumps, as well as the interaction between a pump and a pipeline. It covers a review of fluid mechanics, the modified Bernoulli equation applied to piping systems, the energy equation applied to pumps and piping systems, energy loss in a pipeline and in fittings. Class discussion also includes pump selection process, pump performance measurements, the specific speed-efficiency relationship, affinity laws, the effect of pipeline diameter on required pump size, and net positive suction head.

Participants will learn to use one dimensional flow theory to design an impeller, to design a volute, and to predict how pumps behave in series and in parallel. Also covered is a prediction of critical rotational speed of a pump shaft, shaft stresses, disk stresses, keyway stresses, and more.

You Will Learn To

  • Explain how to calculate radial and axial forces on impeller
  • Calculate shaft deflection and bearing loads, shaft and key stresses
  • Describe approximate head, capacity and efficiency values even before you have made a final pump selection
  • Calculate the effects on pump performance of viscous liquids
  • Identify the pumps to select for operation in series or parallel

Special Requirements
Participants are required to bring a calculator, a flex or French curve, and divider to each class session.

Course Materials (included in the purchase of the course)
Downloadable spreadsheets with calculations and downloadable PDFs of the course presentation.

Who Should Attend
This course is tailored to people who have some pump knowledge and are seeking a deeper understanding of how centrifugal pumps work, and when and how to apply this knowledge. It benefits those who are involved in some facet of pump design or application, or those who are interested in pursuing a career in these areas. Participants should have a degree in engineering and some work-related experience with pumps or equivalent experience in the pump field. 

This ASME Virtual Classroom course is held live with an instructor on our online learning platform. Certificate of completion will be issued to registrants who successfully attend and complete the course.
