Description

This course provides an understanding of positive displacement pumps, their principles of operation, and their applications. The course begins with an explanation of the fundamental differences between centrifugal and positive displacement pumps, and the factors that determine the flow rate of each type.

 

The course then focuses on positive displacement pumps, exploring the different types of pumps and their classifications, including reciprocating piston, gear-type rotary, lobe-type rotary, screw-type rotary, moving vane, and diaphragm pumps.

 

Overall, this course is designed to provide students with a comprehensive understanding of positive displacement pumps, their operation, and applications. Upon completion, students will have the necessary knowledge to select the appropriate type of positive displacement pump for specific applications and to optimise their performance.

What you will learn in this course
  • Understand the fundamental differences between centrifugal and positive displacement pumps
  • Evaluate the effects of liquid viscosity on positive displacement pumps and their maximum speed and flow rate
  • Analyze the impact of slippage on the efficiency of a positive displacement pump
  • Classify different types of positive displacement pumps and describe their operating principles
  • Interpret the characteristic curve of a positive displacement pump on a graph of head versus flow
  • Explain the role of the relief valve in protecting positive displacement pumps from over pressurisation
Who this course is for:
  • Engineering students in mechanical, chemical, or process engineering fields
  • Professionals working in industries such as oil and gas, chemical processing, water treatment, or food and beverage
  • Technicians and maintenance personnel involved in the operation and maintenance of positive displacement pumps
  • Individuals seeking to expand their knowledge of positive displacement pumps and their applications.
