RE: Vacumn Pump
There are a couple types of vacuum pumps.
Mine is made of a
1) Refrigerator compressor
2) Piece of 4" diameter PVC as a tank
3) Vacuum gauge (mounted on the PVC tank)
4) Vacuum switch (connected to the PVC tank)
5) Exhaust tank (plastic bottle aiming upward)
Mine is set to run until the set pressure is reached. I set mine to start running around 3" Hg. It shuts off at about 6" Hg. The switch turns off the 115 volt AC power to the compressor.
A piece of 1/4" diameter plastic tubing is routed from the compressor to the PVC tank. Tubing runs from the tank to the switch. Tubing also runs from the tank to the vacuum bag. The compressor sends oily air into the exhaust tank.
Check out the ViperDog thread to see how to vacuum bag.

RE: Vacumn Pump
The following site shows commercial units.
I know someone that uses the ez-vac system. He swears by it.

The switch may be difficult to find. Try this site if you can't find one locally:

Here is a simplified diagram:
