I don't know much about this subject. My guess is the pump is more than you need but not always a bad thing. Appears to be a good quality product used in septic systems and ponds.
If you buy an undersized pump your grow will crap out right when it starts to flower. I think at an absolute minimum you want to pump to put out is 10 l O2 per minute per bucket. I always went for 15 liters per minute myself. I don't know how much that pump puts out but I suspect it's way too weak to run eight pots.
Remember when buying a pump they will give you the highest ratings the pump can put out under perfect conditions. So your actual output will probably be less. That's probably why I always like to pump rated at least 15 l per minute per bucket.
I just saw the pumps rated output and that should be sufficient. I haven't used those round discs before, what you're really looking for is the smallest possible bubbles. That gets the most dissolved oxygen to your plants.

i use hailea aco 9730 pumps they kick out 60 littres/min, and have a 10 outlet manifold.
i use 8 of the lines in 4 buckets, so 15litre/minute.
i just use the cheap golf ball stones and change them out every 3 grows as they are like sponges for pathogens

I have used the air stone a few times, worked really well but you have to weight it down.
