That would depend on the hydraulic circuit. Basically, you would need to know the required output pressure and flow along with a conservative efficiency for the pump. Typically, the Bernoulli equation is used: the total energy at the discharge is equal to the total energy at the suction. Once you model the system with this equation, you solve for the added pressure, or head depending on your approach, for the pump. Make sure to include all the friction losses. Also, ensure that the net pos. suction head available is greater than the net pos. suction head required. Solving for the pressure or head added by the pump can be misleading since the pump does not dictate the system pressure; the load determines the pressure.
The type of pump used would depend on the application. Some pumps have a high flowrate, but perform poorly with higher pressures and vice-versa. Good luck.

I think you can see it in the box. It depends mainly in the use that you want to give it. The first thing you need to know is the amount of water you are pumping and the height that you want to arise.

You realy need more detail to get a firm answer.
