Dear friends i
I have 2qiestion about the pumps
1-about minimum flow line
For intermittent pump dose it need to consider the min flow.line or not ?
In.our.plant we have two 40kw pump.both work 4 hours per day the designet has not been considered for this pumps min flow line .
Does it need ?
Second question is about pump end of curve.
One.pump.in.our.plany design in end.of curve operation.
I want to see in the data sheet of pump for confirmation .dose it have any place in data sheet to shoe us this pump motot design for end of curve ?
