Constant pressure variable flow rate pump in Simhydraulics

Hello, As a part of a university study I am trying to produce a Simhydraulics model to demonstrate the effects of water hammer. For this I need a source which will produce a sinusoidal flow rate but keep the pressure at a constant whilst doing this. I don't seem to be able to manipulate the blocks into doing this.

Also the reverse case of constant flow rate and oscillating pressure. Either but preferably both are needed.

Cheers in advanced.

yes you can do it by modeling a pump and install a valve after it and give it sinosoidal input, and after that valve use a pressure compensation valve. so you are done
