      yes     

What I know there should be a higher vacuum
then connecting two pumps.

There are ultra high vac pumps (diffusion pumps)
that pull a vacuum of 0,000000001  torr.

These pumps only run if another vac pump is
preswitched.

ok but how about if i had two of 120mmhg is the vacuum strong enough. and how strong must a pump be to pull ketone, whats the minimal in mmhg.

      Pump for ketone     

You can distill ketone with an aspirator ( I did it once ) but it takes longer and is more difficult than with a pump. A typical good aspirator vacuum is 35 mm Hg. A typical good rotary vane pump vacuum is 0.50 mm Hg. I agree with Osmium, your vacuum is not good enough. Don't try to add two pumps, get a good one.
