Simulation of pump down graph

hi community,
I would like simulate the pump down graph of my vacuum pump.
My first test is to use laminar flow, create an air cube of 1m^3 and add a vacuum pump on a side.
The specificity of the vacuum pump is :
flow (m^3/s) pressure(mbar) 1 1333 1 0.8 0 0.8
Normally the simulation would lead to a graph with a decrease from atmosphric pressure to 0.8 mbar. But in my case i have a flat graph at 0.8 mbar.
Can anyone help me ?

- If those numbers represent pumping speed at a few different pressures you will probably want more points.
- Post your model.
