Max pressure is max pressure. 100 psi pump will only make as much pressure as it can make . . . .

Pressure and Flow are 2 very different things.

I take it you are working on an well with an accumulator?

If so the rate at which the accumulator is filled is determined by the accumulators size and the flow rate of the pump @ the pressure you are filling it at (well actually a parabolic curve determined by the flow chart of the pump, and the pressure in the accumulator but . . . . .)
