{"title":"4025674 Fuel Pump for Cumm Q23 Q60 Series Engine","imgUrl":"https:\/\/img.chinax.com\/nimg\/c1\/0a\/21a0733b4789bf4e2af5a9852be0-200x200-1\/4025674_fuel_pump_for_cumm_q23_q60_series_engine.jpg","attrs":{"Condition":"New","Purpose":"for Replace\/Repair","MOQ":"1PC","Oeno.":"4025674"}}
Our 4025674 large-displacement high-pressure common rail pump strictly complies with Cum-mins original QSK series manufacturing standards, designed exclusively for QSK23 ultra-powerful electronic diesel engines mounted on super-large mining excavators, offshore vessels and stationary heavy-duty generators. It fully solves core breakdowns including power limitation under full mining load, unstable rail pressure, excessive black exhaust, hard cold startup and engine flameout during peak power output, supporting direct bolt-on replacement without engine pipeline or ECU modification.
✅ Mining Construction Equipment: Komatsu PC1250-7 Large Mining Excavator, D375A-5 Heavy Dozer
✅ Mine Transport Machinery: Open-pit large haul trucks, rock crushing production lines
✅ Marine Power Equipment: Offshore engineering ships, ocean-going vessel main & auxiliary engines
✅ Industrial Power Units: Continuous-operation high-power generator sets, oilfield fracturing power equipment
Unique Core Product Competitive Advantages
Multi-Plunger Large-Flow Design For Sustained Ultra-High Rail Pressure
Multi-cylinder reinforced plunger layout delivers stable 1600bar peak rail pressure during long-time full-load mining digging and ocean wave vibration. Massive fuel supply capacity eliminates power drop when climbing slopes, full-load excavation and peak power generation, completely different from small-displacement light-duty feed pumps.
Super Hardened Core Components Adapt To Low-Quality Mine & Marine Diesel
Internal plungers and delivery valves adopt deep carburized wear-resistant alloy material, with strong tolerance to high-impurity, high-sulfur fuel widely used in mines and offshore vessels. Thickened cast steel pump housing resists long-term high temperature and strong vibration without deformation or oil leakage.
Special QSK Series Long-Duration Fatigue Bench Testing Before Shipment
Every pump undergoes 8-hour continuous full-load flow test, pressure holding fatigue inspection, solenoid response and overall sealing detection on dedicated QSK23 professional test bench. Each unit calibrated to factory original fuel supply curve to guarantee balanced fuel delivery for all cylinders.
Equipped with original-spec fuel metering electromagnetic valve and pressure stabilization assembly, perfectly match QSK23 ECU control logic, no abnormal fault codes or power limitation alarm after installation, fully compatible with original wiring harness and high-pressure fuel pipes.
Two Quality Grades For Different Long-Term Operation Cycles
We supply full brand-new injection pumps with all brand-new precision internal components for 24/7 non-stop mining and marine equipment; remanufactured pumps replace all worn core parts and re-calibrated on professional test bench, cost-effective for periodic overhaul of intermittent industrial power units.
