A typical vacuum system consists of a series of ejectors and liquid ring vacuum pumps.

What is the working principle of liquid ring vacuum pump?

other technologies are available like dry vacuum pump. 

A Google search should help you out.

A liquid ring pump is basically a positive displacement pump where the liquid functions as the piston. The ingenious concept of having the impeller not on the same center line as the volute causes the liquid to move up and down relative to the impeller fins. I'm sure you will find some visual simulations on the web.

Hi Katamar, thanks for the reply.
And this movement of the liquid causes the vacuum in the volute, right?

Plenty of videos available on YouTube, a good one from Hermetic.
