That would take something along the lines of a 10hp booster. If you are using single phase 220 power, you are looking at 30 to 40 amp range. Will you be using 3phase? Is 220vac the only power you have available for this pump? Will this pump be pulling off a storage tank?
For that much flow, will this be open flow? (such as running in to a pond) or will this pump need to build pressure
to run maybe some kind of irrigation system?
You don't say why you need this kind of water. There are lots of variables that need to be known before the correct pump can be found.
