This heavy-duty diesel unit pump (part identification codes: 0414755014 / 0 414 755 014; common OE cross-references include 0414755002, 0414755003, 0414755008, 0986445006, 20460014, etc.) is precision-engineered for D12/D16 series 12.0L and 16.0L heavy-duty diesel engines (inline and V-configurations). It is widely used in heavy-duty semi-trucks, mining dump trucks, long-distance coaches, and heavy-duty generator sets. As the core power unit for generating ultra-high injection pressures within PLD/UPS fuel systems, it is responsible for instantly boosting low-pressure diesel and precisely delivering it to cylinder injectors—driven by the camshaft—thereby ensuring a stable and abundant fuel supply for large diesel engines.
Manufactured to standards emphasizing "tight-tolerance precision fits" and "stable, ultra-high-pressure output," the pump body utilizes high-strength forged alloy steel. The plunger assembly features aerospace-grade, specially hardened bearing steel with a dense, ultra-hard surface coating that effectively prevents internal scratching and pressure loss caused by fuel impurities. Upon installation, drivers and maintenance technicians will notice immediate, tangible improvements: cold starts are crisp and rapid, and severe vibrations at low idle speeds are significantly reduced. Under conditions such as heavy-load hill climbing, high-load mining operations, or sustained high-speed cruising, the throttle response is sharp and robust, offering smooth acceleration and powerful output, resulting in satisfying fuel efficiency and stable handling.

Long-haul logistics for heavy-duty semi-trucks: Long-distance heavy trucks operating on inter-provincial highways often cruise under high loads for extended periods, demanding exceptional stability in high-pressure generation and sustained power output from the fuel pump. Maintenance teams should replace the unit with this high-precision pump when drivers notice sluggish acceleration, power loss, or a significant increase in fuel consumption—particularly during heavy-load hill climbs. After installation, oil pressure builds up strongly and steadily, allowing the engine to deliver full power; this significantly improves efficiency and fuel economy in long-haul transport operations.
Mining dump trucks and heavy construction machinery operate in harsh conditions characterized by high dust levels, heavy loads, and frequent stop-start cycles. When equipment experiences hard starting, severe idling vibration, or stalling under heavy loads, mechanics can promptly replace the unit pump assembly. Precise oil pressure regulation enables the engine to generate high torque instantly at low RPMs, easily handling heavy loads and frequent stop-start demands while ensuring high operational uptime.
A: Each high-pressure unit pump undergoes full-range pressure and flow calibration before leaving the factory. Provided the fuel lines are clean, professional technicians can install the unit using standard torque specifications and bleed air from the fuel system to put it into immediate service.
A: We operate our own manufacturing facilities and large-scale warehouses, maintaining substantial stock of this model. Standard orders can ship within 24–48 hours, and we can arrange rapid production scheduling for large-volume orders.
A: All high-pressure unit pumps are assembled in Class 100 cleanrooms and undergo 100% dynamic bench testing at high temperatures and ultra-high pressures. We strictly monitor pressure buildup, fuel return volume, and sealing performance to ensure stable on-vehicle operation.
A: We offer a 12-month warranty on this product. Should any performance failure occur due to non-human factors during the warranty period, we provide rapid replacement or technical support to safeguard your interests.
