How vacuum pump generates vacuum?

The principle behind positive displacement vacuum pump is create a vacuum by expanding the volume of a container. For example in a manual water pump, a mechanism expands a small sealed cavity to create a deep vacuum. Because of the pressure, some fluid from the chamber is pushed into the pump's small cavity.

What are the two most common types of vacuum pumps?

There are two basic categories of vacuum pump: Gas Transfer Pumps and entrapment or capture pumps (Figure 1).

Why does a vacuum pump need water?
