tunze 1073.04 pump - optimal outlet diameter 3/4"?

[reefer on a budget]

the outlet on these pumps are 3/4" npt but i want to know what the optimal diameter is to achieve max flow? the flow charts i have seen dont list the diameter used.
anyone know?

ill plumb 1" it that will get the most out of the pumps.

In general, using a larger discharge diameter will reduce head losses and maximize flow. the 1" you propose will work well.
