Morphology
The meaning 'a pump that raises liquid' is directly and transparently derived from combining 'lift' (to raise) with 'pump' (a machine that moves fluids). This noun–noun compound follows a common compositional pattern and would be readily understandable to a B1 learner who knows both constituent words.
Etymology
Lift pump comes from the simple picture of a pump whose job is to lift water from a low place up to a high place, like drawing water from a well into a bucket above. That's why it means 'a pump that raises liquid to a higher level'.
