My own experience with this was not a happy one.
I tried using a tap to control the water flow. This made the pump cycle on and off at a very high frequency - maybe two or times a second. Because a pump takes a very high current when first switched on this blew the fuse. It happened several times (I'm a slow learner.)
I know that others will tell you differently, but I'd say use a pump controller and use the valve as a stop valve, not as a flow control valve.
I certainly wouldn't fit a pressure tank. That is over-complicating matters.
