Morphology
The meaning is directly derivable from combining 'vacuum' (an empty space lacking air) and 'pump' (a machine that forces fluids or gas), so a vacuum pump is transparently a device that pumps to create or maintain a vacuum. This noun–noun compound follows common technical composition patterns found across languages, making it immediately interpretable by a B1 learner who knows both constituents.
Etymology
Vacuum pump comes from a clear image: vacuum means 'empty' and pump is a machine that moves or pushes, so it is a machine that pumps air out to make a space empty. That's why vacuum pump means a device that 'removes the air or gas' from a closed space to create a vacuum.
