i need some help becoase i become confused
according to pump characteristic curve if the flow rate increased the head will decreased the question is how i can increase the flow rate and what is the relation of RPM with head and flow rate

Have a look at the pump affinity laws: http://www.engineeringtoolbox.com/af...awsd_408.html

Pump head and flow rate relation
By combining the first and second equations, you get an equation that tells you that by lowering the pressure resistance in the system, you'll get an increase in flow.
