Oil Pump
Oil Pump
The BMW N55B30 is a 3.0-liter inline-six, single-turbo, TwinPower Turbo gasoline engine introduced between 2009 and 2015 to replace the iconic N54 engine.
It was widely used in the high-performance 35i variants of BMW’s mainstream models, including the 1 Series, 3 Series, 5 Series, X3, and X5. Its oil pump is responsible
for providing stable oil pressure to the engine’s crankshaft, bearing shells, timing system, and turbocharger across the entire speed range.
The BMW N55B30 engine oil pump is a key component of the engine lubrication system. It supplies engine oil to essential internal components and supports proper lubrication under
different engine speeds and operating loads.
Designed for the BMW N55 engine family, this oil pump uses a variable oil-delivery control system. The engine management system regulates pump output through an
electrohydraulic oil pressure control valve, helping match oil supply to engine operating requirements.
This product is intended for professional automotive parts distributors, engine rebuilders, repair workshops, importers and wholesale buyers.
Important: Oil pump part numbers and compatibility may vary by vehicle model, production date and engine configuration. Please confirm the required OE number or provide the vehicle VIN before ordering.
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.

The oil pump circulates engine oil through the lubrication passages to help protect moving components, including crankshaft bearings, connecting rod bearings and valvetrain components.
The N55 lubrication system uses controlled oil delivery to meet engine requirements under different operating conditions. Correct pump operation is important for maintaining
the designed lubrication performance.
The N55 is a turbocharged engine. Correct lubrication system performance is essential to engine operation and the protection of internal components.
A replacement oil pump may be required when the original unit has suffered mechanical wear, damage, contamination or a verified oil-pressure-related failure.
The root cause should be diagnosed before replacing the component.
