Oil Pumps Introduction

The oil pump is a device in the lubrication system, which can push the oil from the oil bottom to the top of the engine, which is also used to improve the oil pressure and to ensure a certain amount of oil to force the oil supply to each friction surface. The oil pump increases the pressure of a certain amount of oil and delivers it to the friction surface of the engine's moving parts through the main oil passage on the cylinder block. Oil pumps can also be divided into many series, such as:

Gear Pumps: Gear Pumps are also called Twin Gear pumps. It is design includes two gears that rotate in opposite directions. This design is used in Chain Driven pumps/Gear-driven pumps most frequently.

Vane Pumps: Vane pump is used more and more widely because of their ability to variable flow control. Unlike other pumps, it can adjust the flow of oil due to its sliding blade design.

Crescent Pumps/Rotor Pumps: Rotor pumps are commonly used in most crankshaft-driven pumps, and this design consists of one large external gear and one small inner gear sitting off-center one another. The Crescent-shaped void left between the two gears is where the flow control and vacuum are produced.
