That looks like the identical roller pump that I have on my three point mounted sprayer.
If so, you will need a pressure regulator and provision to return water to the tank when the discharge nozzle is closed. Otherwise you will dead head the pump.
If you never close the discharge while the PTO is on, simply connect the inlet to the bottom of the tank and the outlet to the discharge hose.
