Description
Product Overview
The oil pump is assembled on the outside of the CP3 common rail high-pressure oil pump and relies on the internal spring plunger to reciprocate to extract fuel from the fuel tank. The fuel is pre-boosted and then sent to the high-pressure plunger chamber, providing stable low-pressure fuel supply. Under long-term heavy mining conditions, impurities in diesel washing the engine compartment, alternating high and low temperatures in the engine compartment, fatigue of the plunger spring, wear of the internal cavity of the pump body, and aging of the oil nozzle seal, problems such as reduced fuel supply flow, air intake in the oil circuit, inability to establish standard rail pressure of the high-pressure oil pump, repeated ignition starts of the vehicle, and weak acceleration power may occur. This product has standardized specifications for the flange hole distance, oil nozzle thread, and plunger stroke. After disassembling the high-pressure oil pump, the oil pump kit can be replaced separately to repair the failure of fuel supply. It is suitable for large excavators, heavy-duty loaders, and long-distance trucks with electric control common rail diesel engines for maintenance and repair.
Core Advantages of the Single Product
The black cast aluminum pump body is integrally cast, lightweight, resistant to high temperatures, and not prone to deformation.
The entire cast aluminum is integrally cast, with a surface coating for corrosion resistance and wear resistance. It has low self-weight, fast heat dissipation, and can withstand continuous high-temperature environments in the engine compartment. It is not prone to cracking or deformation in the internal cavity under long-term vibration conditions, maintaining a stable fuel flow cavity volume.
Double-sided symmetrical threaded oil outlets + black protective rubber caps, with assembly sealing and dust-proof
Standard rolled threads on both sides of the oil outlets, paired with soft black protective rubber caps. During storage and transportation, it can isolate dust and impurities. After assembly, it can be combined with oil pipe sealing gaskets to prevent air intake in the low-pressure oil circuit and fuel leakage.
Multiple groups of flange fixing holes on the pump body surface + center positioning column, with precise alignment assembly without offset
The pump body surface is reserved for multiple specifications of fixed holes. The center raised positioning column precisely fits into the oil pump installation base, ensuring high assembly coaxiality and no eccentric jamming during the reciprocating motion of the plunger, and maintaining a stable fuel supply flow.
Complementary independent spring plunger pair, with balanced spring force for stable fuel supply linearity
A combination of stainless steel spring + hardened plunger, with strict control of spring force tolerance, smooth mirror surface grinding without burrs, uniform fuel suction flow during reciprocation, and elimination of the problem of fluctuating low-pressure fuel pressure.
Independent dual oil circuit diversion structure, with low supply resistance and不易 emptying fuel
The pump body has a dual oil circuit diversion channel， reducing fuel suction resistance. Under heavy-load and climbing conditions of the vehicle， it will not occur fuel suction failure or sudden drop in rail pressure， ensuring stable power output for heavy loads.
Factory-installed complete flow sealing calibration， no need for secondary debugging during assembly
Each oil pump kit is equipped with a unified spring plunger pair for on-machine detection of fuel supply flow and low-pressure sealing performance. The factory parameters match the corresponding oil pump model， and after assembly， it can quickly restore the normal pressure building ability of the oil pump， reducing maintenance time.
