What pump to get

Hi all, I have a small greenhouse with two 55g barrels for watering over winter. I am looking for advice on what pump to get to pump water out of my barrels to my plants. I want something that I can mount and then run a hose into each of the two barrels depending on which I’m drawing from and want a small showerhead like flow from the hose to plants. I am currently looking at the Wayne pc2 portable transfer pump, but am not sure if this is too much power for what I’m looking for. My hose would be a maximum on 30ft or so. Any advice is welcome. Thanks!
