Increasing water pressure without increasing pump output

[newideaman]

I am curious as to whether a nozzle at the end of a pipe that is completely submerged in water and has a pressurized flow being pumped through it in a closed condition can increase the amount of flow and pressure of the water in a pipe fixed to the exit side of that nozzle if the nozzle uses the advancing flow going through it to suck in water that is on the outside of the pipe. It may work if the pipe on the exit side has more space in it or is short to the output into the water.
