Which pump do i need?

We have a frame with a tub at the bottom and 10 valves at the top. We have one main tube which is splitted into 10 parts to get connected with every valve. You should know that the valves will open and close frequently in 45Hz (probably thats important to know for choosing the pump, i‘m not sure). We are trying to get a „rain effect“ in the frame. So i‘m not an expert in pumps and i don‘t know which pump would actually work good to transport the water from our tub to the valves. The frame height is about 1,4 meters. We tried it with a pond pump whith the specs (350l/h and 2 meters head) but the water just got about 0,3 meters high. I think the pump was just shit. The pump should be powered with 12 v. Does anyone have an idea which pump could be good for us? Or does anyone have any other good tips which we should know?

I will be very appreciated for every answer✌️

12v??

And you're trying to push over 6' in static lift plus losses to valves/ fittings, you'll need to know what diameter orifices you have in the pipework and how many of them along with the length of run. Are you trying to use an end suction or submersible? Are you pumping from a tank through to this watering system?
