Course Length: 1 hour

 


There are lots of courses available on how to size a centrifugal pump. In the past the only solution in many cases was to trim the impeller to make it work properly or to close a valve to get the right flow.  Now with the use of Variable Speed Drives we have found new ways of doing things.  Do I still need to trim the impeller?  This course will answer that question.
