In one of my project we have a requirement of 2500 gpm fire water flow. Instead of providing one 2500 gpm electrical pump and one 2500 gpm diesel pump we have provided 2 x 1250 gpm electrical pump and 2 x 1250 gpm diesel pumps. Now the problem is what will be the sequence of operation pumps. For example, normally if electrical pump does not operate than diesel will automatically start with pressure drop setting in the panel. But in my case is one electrical pump is working and one is not what will be the procedure. Do we have to stop the working electrical pump also before starting fo diesel pump?

 

Appreciate the support for the solution.
