Description
Product Overview
The 9323A350G high-pressure common rail oil pump is a core fuel supply and boosting component for small and medium-sized diesel equipment. It integrates low-pressure oil delivery, high-pressure boosting, and electronic flow control in a single integrated structure, continuously delivering stable pressure fuel to the high-pressure fuel rail. Old oil pumps with worn-out internal pistons, failed pressure regulating valves, and leaking shell seals can cause abnormal fuel supply. Replacing the entire machine can once fix all the oil circuit faults. It is suitable for light trucks, small excavators, agricultural machinery, and mobile generator sets for maintenance and replacement.
Unique Core Features of the Single Product
Integrated cast aluminum compact pump body, lightweight and balanced heat dissipation
The entire machine is formed by high-pressure casting aluminum, with no joint gaps in the internal oil circuit, and the overall volume is small, suitable for compact engine compartments; the shell has a multi-rail heat dissipation structure, and the cylinder body can quickly dissipate heat under high-temperature conditions, slowing down the aging speed of internal sealing components.
Integrated side-mounted installation flange, stable and firm assembly and fixation
The pump body on the right side is equipped with a thickened installation flange plate, with multiple standard locking holes reserved, no additional adapter brackets are needed, the bolts are tightened, and the force is uniform, making the oil pump less likely to shift under vehicle bumps and equipment vibrations, and the threaded interface is less likely to loosen and leak.
Red and blue dual-color pipeline protection plugs, dust-proof and impurity-proof in the oil circuit
The inlet and outlet oil pipelines are factory-assembled with red and blue plastic protection plugs, which isolate dust and sand during storage and transportation, preventing impurities from entering the pump body and causing the piston and valve components to get stuck, reducing the probability of installation faults.
Integrated electric control flow regulating valve body at the top, sensitive oil pressure regulation response
An independent electric control pressure regulating component is built at the upper end of the pump body, which collects the dynamic pressure of the oil circuit and adjusts the fuel output in real time. The rail pressure responds quickly and synchronously to the throttle increase and decrease load, ensuring smooth engine acceleration without power breaks.
Multi-point bolt sealing structure, long-term anti-leakage of the shell
Each end cover and connection position of the pump body are evenly locked with multiple bolts, and the internal is equipped with high-temperature and oil-resistant sealing gaskets. Under long-term high-temperature and high-pressure working conditions, the seal is less likely to fail, and there is no leakage or accumulation of dirt at the connection gap, preventing oil leakage and contamination. Applicable scenarios
This product is compatible with small and medium-sized four-cylinder common rail diesel power units and is widely used in light freight trucks, small wheel excavators, agricultural tractors, mobile diesel generators, etc. It is suitable for urban roads, fields, construction sites, and short-distance, low-load, and alternating high/low temperature working environments.
