Course Introduction:
Engineers are often faced with a difficult decision on selecting the best type of pump for a pump station design. Two common choices are turbine (VT) pumps and horizontal split case (HSC) pumps. Often both VT and HCS pumps will both function well for an application. The choice between VT and HSC pumps is often not obvious as many factors are involved in a pump selection and sizing process.
This engineering continuing education course addresses the challenge of comparing and choosing a VT or HSC pump. For each pump type, API and HI standard designations are explained, major pump features are highlighted along with figures, pump operations are explained, and common applications are covered.
Next, key factors are analyzed for making pump comparisons, with an explanation as to which pump type has the advantage for each factor. A pump type selection tree is introduced, and a pump scoring approach is presented. Finally, two example applications are presented: one with VT pumps chosen and one with HSC pumps chosen.
Learning Objectives:
• Understand classification of different types of pumps
• Become familiar with the standards organizations that publish pump standards
• Understand the benefits to different types of impellers
• Learn typical advantages to VT and HSC pumps
• Review the important factors in pump selection
• Become familiar with logical steps in a pump type selection tree
• Learn to perform comparison scoring and make a final selection
