Morphology

oil + pump

The compound combines 'oil' (the substance) with 'pump' (a machine that moves fluids), so the meaning 'a pump for oil' is directly and predictably derived from its parts. This noun–noun modifier pattern is a common, compositional naming strategy across many languages, so a B1 learner who knows both words will readily infer the MWE's meaning.

Etymology

Oil pump comes from the simple idea of a pump that moves oil to the parts of a machine that need it. Imagine a pump pushing oil through small pipes to stop parts rubbing and getting hot, so today oil pump means the device that circulates oil to protect and cool moving parts.
