Come on, come on, let’s take a look at the differences between series and parallel connection of centrifugal pumps
Thread Content
As shown in the figure, let’s deepen our understanding of this phenomenon; we can also learn about the characteristic curves of centrifugal pumps in parallel and series configurations. Could someone expert tell me which book this information comes from?
There are books on principles of chemical engineering or process fluid machinery, right?
Is it from the industrial pump selection manual?
Learned it, thanks for sharing http://www.shschultz.com/
Yes, as can be seen from these two diagrams, both series and parallel connections can increase the pump’s flow rate and head, with the amount of increase depending on the piping. Pumps should be connected in parallel when the pipeline characteristic curve is flat, and in series otherwise, when it is steep. Regardless of the method used, it is necessary to ensure that the pump’s stable flow rate point lies within the efficient range.
