40-65psi is the perfect range of pressure needed. Lots of available choices depending on your initial aim and budget.
Procon is the popular choice because of its reliability and the pressure can be adjusted to suit the application (if your carful). Shurflow diaphragm pumps as used in caravans are a popular one also. If you wanna go compact, tiny pulse pumps are the way to go
