Model 2897672 integrated high-pressure common rail pump is exclusively engineered for Cum-mins QSK23 series 23-liter heavy-duty industrial engines, adopting HPCR high-pressure rail control system. It delivers stable ultra-high fuel pressure for large mining excavators and stationary power units, resolving frequent rail pressure fluctuation, slow power response, overload power drop, cold start difficulty and engine fault code P0087.
Cross interchange OEM numbers: 2897672, 4307242, 4087997, 4307242EK80. Standard flange drive interface, consistent pipeline thread and electronic sensor plug with original pump, direct bolt-on replacement without engine mechanical modification or ECM recalibration.
Core Competitive Advantages
Dual Plunger Reinforced Pressure Output Structure
Dual thickened alloy plunger design inside pump body, matched with reinforced cam drive gear, sustain long-hour full-load operation of 90–120 ton large excavators. Stable 1600–2000bar continuous pressure output, avoid rail pressure collapse under sudden heavy load lifting, greatly reduce abnormal power loss during mining operation.
Built-In Dual Electronic Pressure Sensors With Anti-Vibration Shell
Equipped with original matching blue plug pressure sensor and flow control solenoid, integrated vibration damping aluminum alloy pump housing. Resist continuous bump vibration of mine site rough roads, effectively prevent sensor signal loss and unstable fuel supply common on aged pumps. Multi-layer fluorine rubber composite seals at all oil ports eliminate internal and external fuel leakage risks.
QSK23 Exclusive Full-Cycle Bench Calibration
Each finished pump undergoes dedicated QSK23 HPCR system testing, including low-speed idle flow test, full-load high-pressure holding test, sensor signal matching test and long-cycle leakage aging test. Complete test data report attached with every pump, guarantee uniform performance for batch mine equipment overhaul.
Mainly matched with 23L QSK23 engine installed on large mining excavators, mine haul trucks, port loaders, marine auxiliary engines and high-power generator sets. Centralized inventory product for global mining machinery maintenance factories and marine engine repair yards, high turnover spare part for heavy equipment dealers.
