Simple Pump Application Question/Suggestions?
(OP)
I am trying to design a simple pumping system to transfer water over a 10' high wall that divides two basins. I want to use a 7.5HP submersible pump for this application. Design flow will be ~1-1.3 MGD. Static head will vary between 2 and 7 ft. In order to create sufficient TDH, I considered using 4" piping with a few bends, but the velocity in this size of pipe seems too high (>15'/sec). It would be nice not to have to use a valve to create additional head. Any ideas? Could an orifice plate be sized to limit flow (BEP for this pump is ~750 GPM @ 18 FT TDH)?

Why are you worried about velocity - using the pipe system to reduce head is not much different than using a valve or orifice plate.
Alternately select a pump more suited to the application.
