I usually do that kind of flow/head using two pumps in series in one pump station. If at all possible I use one submersible and one vertical dry pit, with the dry pit mounted directly above a submersible. I use mechanical seals in the dry pit pump. I generally try to find matching pump curves and split the head more or less evenly, although this is not required. I start the submersible first (20-30 seconds) and place an air release valve between the discharge of the dry-pit pump and its’ check valve. I treat the two pumps as one, that is no cross connection piping. I try to avoid 3600 RPM motors and pumps but this is a personal thing. You may look at Gorman-Rupp, they have a two pump in one assembly, with a centrifugal pump mounted above a suction lift pump and driven by one motor. And just to show my age, you may try an ejector station, although the flow is a little high. Whatever you do, pay attention to the check valves and the potential for surges and hammer in the discharge.
