Suitable pump for 3 open flow 1" FloraFlex bubblers?

I can't find the right pump to run 3 1" open flow floraflex bubblers, I'm running 2 1/4" stakes to each pot and just trying to reduce manual labor and potentially implement automation later. Mainly just trying to save my back.

I've tried as big as a 1/2 horsepower mondi pump and it did not properly operate the drippers, some were spitting water some weren't. I know FloraFlex recommends 15 psi at least and the math they give is for each foot of head the pump can do you multiply it by .433 to get the rough PSI rating.. Considering most hydroponic specific pumps are not high lift what the hell pump do I need to power this setup?

Current setup is 1" PVC with 3 open flow bubblers and 24 basket drippers..

Thanks!

I think some people look for RV pumps as they're lower flow but higher PSI. There was something about those style of pumps where they're geared more towards higher pressures than flow rates. Many of those are 12v based I think, so you'd need a power supply for them. Not sure if there's an advantage to that path versus a bigger traditional pump like the 1000gph suggested above.

I don't think an RV pump would be strong enough for 24 1/4 drippers.
