The current gauge pressure of the side channel pump in the recycling stream is limited to 4bar and we would like to increase the pressure to between 5 and 7bar.
In the picture below point 1) is the actual operating point of this system assuming that the characteristic curve of this 20 year old pump hasn't changed.
now to my question:
lets say I would use the pump 1204 instead of 1203 would the new operating point result in point 2) marked in the picture or would it just change the volumetric flow and we end up in point 3) and the gauge pressure wouldn't change at all?
any feedback from a knowledgeable and kind soul would be greatly appreciate
