I believe it makes pressure regulation easier. Pressure regulation works by
returning not needed flow (that is most of the forward flow) to the tank.
With pumps in parallel the second pump doubles the flow which requires quick
action from the regulator; also, the maximum pressure drop in the return
line (0.25 bar?) is easily exceeded . With pumps in series the second pump
does almost nothing (except double the maximum attainable pressure at no
flow condition - not relevant - and making it doubly certain that the
required flow is there).
