Vacuum uses the surrounding atmosphere to create work force by pulling on, rather than pushing , a work piece. Evacuating air from a closed volume develops a pressure differential between the volume and the surrounding atmosphere.
How vacuum is created?
A vacuum can be created by removing air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli's principle.

Why is it impossible to pull a fluid?
What is really happening is that the increase in volume reduces the pressure in the chamber so that atmospheric pressure pushes the fluid in. It's always to do with pressure – which is pushing. There is no pulling.
