What is an Oil Pump Gear?
An oil pump gear is a component inside an engine’s lubrication system. It drives the oil pump and helps circulate engine oil through the bearings, pistons, camshaft, and other moving parts. By maintaining oil flow and pressure, the gear ensures proper lubrication and cooling during engine operation.
Oil pump gears typically work in pairs, such as inner and outer rotors in a gerotor pump or two spur gears in a gear-type pump. As the gears rotate, they create suction that draws oil from the sump and then pressurizes it before sending it through the engine’s oil passages. The geometry and fit of the gears directly affect pumping efficiency, pressure stability, and noise level.
These gears are commonly made from materials like alloy steel or P/M iron because they must withstand continuous load, wear, and thermal cycling. Precision and durability are important, as poor gear performance can lead to low oil pressure, increased friction, or engine damage.
BLUE Quality Management System
BLUE produces oil pump gears under the strict supervision of ISO 9001:2015 and IATF 16949:2016 quality control systems.
We conduct a full range of tests, including dimensional and positional tolerances, hardness, tensile, and fatigue strength, to assure that your oil pump gears meet high standards and specifications.
BLUE uses blister trays and more than three layers of cartons to securely package your products, ensuring that all oil pump gears are delivered safely and intact.
These quality control measures ensure that each oil pump gear delivered to you has high precision, hardness, strength, and wear resistance, allowing the oil pump to perform at its best.

How Oil Pump Gear Works?
The working principle of a gear oil pump relies on the meshing of gears to transport oil.
The working space is defined by the grooves between the pump body, side cover, and gears, which is divided into a “suction chamber” and a “discharge chamber” by the meshing area.
As the gears rotate, the teeth in the suction chamber disengage, increasing the volume and creating a pressure drop that draws in oil.
The oil is then carried to the discharge chamber, where the meshing gears reduce the volume, forcing the oil out.
FAQ's
Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
Rotor Oil Pump:
The rotor oil pump operates using two synchronized rotors—an inner and an outer rotor—that rotate in opposite directions. As they rotate, a vacuum is generated at the inlet, which draws the required liquid into the pump.
Gear Oil Pump:
The gear oil pump works by using a pair of parallel gears inside the pump housing. When these gears rotate, a negative pressure is created on the suction side, which draws liquid into the pump. As more liquid is drawn in, pressure builds up on the discharge side, forcing the liquid out of the pump.
