can you hook up a water pump without a pressure tank?

Of course, but if you have a pressure switch on it, the pump will cycle on and off CONTINUOUSLY while water is being used.

The pump has a "maximum" output pressure, with or without flow. If the pump is running but the outlet is closed the pump will not stop, but the water WILL overheat and turn to steam.

I just ran across what is called an on demand pump that operates without a pressure tank. It did start each time water was used but this pump is made for this application. It looks like a shallow well jet pump.
