Core components of high-performance construction machinery
The oil pump is a key component to ensure that the internal parts of the engine are adequately lubricated. In the American engineering machine 3116 and 3126 series, the design and manufacturing process of the oil pump has reached a very high level, ensuring the stable operation of the machine under various harsh conditions. Whether on a construction site or in a mine, these oil pumps provide reliable lubrication support to extend engine life.
Model 2W8092: Efficient and durable choice

Model 2W8092 oil pump is widely used in 3116 engines. Its efficient oil circulation system and durable design make it the first choice for many users. This type of oil pump adopts advanced gear design, which can maintain a stable oil supply in a high-pressure environment and ensure that the internal parts of the engine are fully lubricated. In addition, the shell of 2W8092 is made of high-strength aluminum alloy material, which has strong corrosion resistance and long service life.
Model 2W8091: Stable and Reliable Performance
Model 2W8091 oil pump is also suitable for 3116 engines, and its stable and reliable performance has won high recognition in the market. 2W8091 uses precision-machined gears and seals to ensure that there will be no oil leakage during long-term operation. In addition, this type of oil pump is also equipped with a temperature sensor, which can monitor the oil temperature in real time, find potential problems in time, and ensure the safe operation of the engine.
Model 705403: suitable for 3126 engines
The 705403 oil pump is specially designed for 3126 engines, with excellent lubrication and long service life. This type of oil pump adopts a two-stage gear design, which can provide sufficient oil pressure at low speed to ensure that the engine can obtain good lubrication effect under starting and low load conditions. In addition, the 705403 is also equipped with an integrated filter to effectively remove impurities in the oil and protect the internal parts of the engine from wear.
Model 4W223: Multifunction Solution
The 4W223 oil pump is not only suitable for 3116 and 3126 engines, but also performs well in many other mechanical equipment. This type of oil pump adopts a modular design and can be flexibly configured according to different application scenarios. The biggest feature of 4W223 is its strong adaptability, whether it is under extreme low temperature or high temperature conditions, it can maintain stable performance. In addition, this type of oil pump also has a self-cleaning function, which can automatically remove blockages in the oil circuit to ensure that the oil circuit is unblocked.
