It is always a challenge to get the right pumps!
The utilization of EPANET and Pipe Flow Expert is really good practice.
Utilizing both programs EPANET and Pipe Flow Expert would not only speed up the pump selection but also make a much better pump selection.
Now, it needs to be said that EPANET is an open-source and free program, whereas Pipe Flow Expert is a commercial tool for engineers. EPANET is very useful when all features are implemented as intended, but it does not have the possibility to make good pump selections.
Pipe Flow Expert remains a program of choice when it comes to selecting pumps in elaborated distribution networks. But also in most cases, it is very useful finding the causes of failure.
