Morphology
The compound denotes a 'ram' (a mechanical device) that is hydraulic—i.e., driven by liquid pressure—so a learner who knows 'hydraulic' and 'ram' can infer it is a device using water/pressure to move or lift water. This is a straightforward noun–modifier composition found cross-linguistically (e.g., Spanish 'ariete hidráulico'), so the basic meaning is transparently derivable even if the exact pumping mechanism is technical.
Etymology
Hydraulic ram comes from how the machine works: hydraulic means water power and ram means a strong push. Fast water is suddenly stopped by a part and that sudden push lifts some water up a pipe, so the device can 'raise water' without any other power.
