Anyway, BigInch is dead right, 545 to 80 gpm at similar head rating is far too much turn-down for a centrifugal pump to operate trouble free.
Although you will find a pump on which you could fit the duties to the H/Q curve - you can then join the ranks of those who are always asking, Why am I having bearing and seal failures, why am I breaking shafts etc?
Use 2 pumps, save power and all the headaches.

Maybe you should consider a progressive cavity pump with a VFD?
These pumps are also very tolerant to particles.
