Centrifugal and Positive Displacement Pump Basics, 3 PDH
(Centrifugal and Positive Displacement Pump Basics)


The pumps widely used in industry and by commercial buildings and municipalities, can almost all be classified as either centrifugal pumps or positive displacement pumps. The general components and operating characteristics of these two types of pumps are covered in this course, along with discussion of corrective and preventive measures for various pumping problems.

This course is intended for civil, mechanical, chemical, environmental, and industrial engineers, as well as anyone who works with fluids and pumps. An attendee of this course will gain knowledge about centrifugal and positive displacement pumps.

In this course, you need to review the material in the Department of Energy Fundamentals Handbook, DOE-HDBK-1018/1-93, "Mechanical Science Module 3 - Pumps"

Upon completing your review of the course material, you need to take a multiple choice quiz consisting of fifteen (15) questions to earn 3 PDH credits. The quiz will be based on the entire document. 80% correct is required for a quiz passing grade.
