My suggestion would be to contact the company (WeiliBao) about the controller requirements of their DC brushless pumps, because it is not at all clear exactly how those pumps are powered or controlled from the information on their site.
For anybody knows, they have a built-in integrated controller (much like PC fans - which are brushless as well, despite having only positive and negative leads!), or the company has a controller specified, either that they supply, or they reccommend from another company.
Such a pump may not even be controllable from an R/C-style brushless DC motor controller (perhaps the pump needs a controller that has feedback capability, or not, or...?).
Really - you need a proper datasheet and information about this pump before you can even decide how to control it. I would look into that, first...
