Oil Pump
Oil Pump
The Nissan QR25DE is a 2.5-liter inline-four gasoline engine introduced in the early 2000s as part of the QR engine family. It features an all-aluminum cylinder block and head,
DOHC 16-valve design, and is widely used across Nissan’s global lineup. Power output typically ranges from 152 to 182 hp depending on the application and market.
The oil pump is a gerotor-type unit driven directly by the crankshaft. It supplies pressurized oil to the crankshaft bearings, camshafts, valvetrain and other critical components,
ensuring proper lubrication under all operating conditions. Early versions are standalone pumps, while some later applications integrate the oil pump with a balance shaft unit.
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.
