The oil pump forces the motor oil through the passages in the engine to properly distribute oil to different engine components. In a common oiling system, oil is drawn out of the oil sump (oil pan, in US English) through a wire mesh strainer that removes some of the larger pieces of debris from the oil.
Oil pump may refer to: Hydraulic pump, which pressurizes hydraulic fluid in a hydraulic system; Oil pump (internal combustion engine), a part of the lubrication system that pressurizes motor oil for distribution around the engine; Pumpjack, often used to pump oil out of wells; Submersible pump, often used to pump oil out of wells
A diagram of a pumpjack. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1]It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface.
Some vessels store liquid until it is pumped out. The controller (LIC) acts to start and stop the pump within a specified band. For example, start the pump when the level rises to 0.6m, stop the pump when the level falls to 0.4m. High and low level alarms (LAH and LAL) warn operating personnel that levels are outside predefined limits.

The oil collects in sump (1), is withdrawn continuously by scavenge pump (2) and travels to the oil tank (3), where gases entrained in the oil separate and the oil cools. Gases (6) are returned to the engine sump. Pressure pump (4) forces the de-gassed and cooled oil (5) back to the engine's lubrication points (7).
