The regulator is only on the city water source side and has no effect on the pump. The reason you are seeing large swings in the water volume is the pump can provide more water than you are drawing at that point in time and thus shuts itself off. It will not come on again until the pressure switch in the pump calls for it to come on.
One way to reduce this is to install a small accumulator tank. These tanks have a bladder inside and you can pressurize one side of the bladder with air. By varying the air pressure you can reduce the frequency of pump cycles to fit you life style.
The tank can be installed anywhere in the cold water system down stream of the pump.
If you install an accumulator you should cycle the pump by the switch several times while drawing off the antifreeze when you dewinterize. This insures you purge the accumulator of antifreeze and wont taste it later.
