Description
Product Overview
The pump head is the core boost and distribution unit of the CP3 high-pressure oil pump. It builds high pressure by compressing fuel through the reciprocating motion of the piston, and steadily delivers high-pressure fuel to the common rail pipeline. Under long-term heavy mining conditions, erosion by poor-quality impure diesel, and continuous ultra-high oil pressure impacts, the internal piston mating surfaces may wear out, and the sealing structure may fail. This can lead to internal leakage of the oil circuit, engine acceleration weakness, idle vibration, black smoke from the exhaust, and diesel seeping into the engine oil to dilute the lubricating oil. This product is manufactured with an integrated shell, piston, and oil passage, and the installation holes and thread specifications are standardized uniformly. Maintenance does not require on-site grinding and matching, significantly reducing maintenance time and suitable for medium-sized excavators, heavy-duty loaders, and long-distance freight trucks that are equipped with CP3 common rail oil pumps for maintenance.
Core Advantages of the Single Product
Thickened cast steel integrated shell, high pressure-bearing, anti-deformation, and leakage resistance
The entire shell is cast in one piece, with a thickened pressure-bearing structure. The internal oil passage is integrated without any joint gaps, capable of withstanding thousands of bar of high-pressure fuel for long-term impact. It is less likely to crack and leak in hot and bumpy construction sites and mines, significantly reducing the risk of oil leakage.
Multiple standard flange installation holes for precise assembly positioning without deviation
Multiple sets of fixed flange holes are reserved around the shell. After proper installation, the pump head has no radial or axial displacement, and the piston reciprocating motion has no eccentric wear, ensuring the long-term stability of the supply pressure.
Full-port yellow dust-proof sealing caps for precise protection of the oil passage
All inlet, outlet, and pressure adjustment ports are equipped with yellow oil-resistant plastic caps. During storage, transportation, and disassembly, dust and impurities are isolated, preventing fine particles from entering the cavity and scratching the precise mating surface of the piston, and preventing assembly-induced pressure leakage.
Built-in paired precision piston pairs, stable linear oil supply and uniform rail pressure
The internal piston is precisely ground to an ultra-fine mirror surface with the pump body, and the mating gap is strictly calibrated. The internal leakage of high-pressure fuel is extremely low, allowing the equipment to maintain stable rail pressure under both high and low load conditions, eliminating acceleration weakness and speed fluctuation problems.
Internal multi-channel oil passage layout, balanced fuel supply and reduced black smoke
The multi-channel independent oil passage distribution structure inside the shell distributes fuel smoothly, with small differences in fuel supply volume for each cylinder. The engine runs smoothly, and the fuel is fully burned, reducing carbon deposits in the cylinder and black smoke emissions.
Factory bench testing for overall calibration, no need for secondary adjustment after replacement
Each pump head is independently tested for oil supply pressure, flow uniformity, and sealing performance. The factory parameters are unified, and after assembly, it is directly matched with the original vehicle's electronic control system, quickly restoring the equipment's power output. Applicable scenarios
This product is suitable for medium-sized mining excavators, heavy-duty wheeled loaders, long-distance heavy-duty freight trucks, and high-power fixed diesel generators equipped with CP3 electronic common rail fuel supply system. It is applicable for 24-hour continuous heavy-duty operations in mines, long-distance freight transportation, construction site high-temperature vibration, and dusty and impure diesel corrosion environments of heavy electronic common rail diesel engines. It is used for replacing the core components of the high-pressure oil pump of heavy electronic common rail diesel engines.
