Hi,
rated flow= design flow = normal flow + some margin
for the other questions it probably has to do with what you supplied to the vendor (specification sheet) ,
To get a better answer supply your specification sheet and pump curve with operating point ( TDH vs Qv) from vendor.

Norma flow rate - 0.05GPM
Rated flow - 1 GPM
differential pressure required - 50psi

If your service requires flow conditions that the pump cannot satisfy, then the pump is not suitable. The pump curve you attached indicates the maximum flow of the pump is less than 0.01 gpm.

Norma flow rate - 0.05GPM
Rated flow - 1 GPM
differential pressure required - 50psi
Sorry for the error "GPM". actually its GPH
Please refer the below parameters:
Normal flow rate is 0.05 GPH
Rated flow is 1 GPH
Differential pressure - 50psi

Hi ,
Can you share a process description for better understanding ? more info are also needed about the pump technology and vendors .
BTW one vendor is never sufficient to make a choice !
Good luck

This pump only delivers ~0.5 gph @ 50 psi. So, 1 gph is NOT the rated flow.
