A pump doesn't pump pressure, it pumps volume that's measured in GPH. That was taught in Army Engineer School in the 60's and had to be common knowledge long before that.

The pressure of any full displacement pump will be dictated by the restriction it encounters before being dumped back into atmospheric pressure.
