Common Rail Diesel Oil Pump Model: D28c-001-800 094000-0551 094000-0550 for Sdec D6114

<Product Description> This industrial-grade heavy-duty diesel engine high-pressure common rail fuel pump (OE No.: 094000-0551) is an ultra-high-pressure fuel supply core developed specifically for extreme loads and long-term operation. This product is perfectly compatible with Hino P11C series large-displacement diesel engines and is widely used in Hino 700 series heavy trucks, large concrete mixer trucks, cranes, and various port special-purpose machinery.

Adhering to the manufacturing philosophy of "constant rail pressure and strict prevention of internal leakage," the piston and cam friction pairs undergo extremely rigorous micron-level surface hardening and low-friction coating treatment. After replacing the pump with this new high-pressure pump, the driver can instantly notice a cleaner and crisper engine ignition, and the rough vibrations of the vehicle at idle disappear. When the heavy truck is fully loaded and climbing steep slopes or when special machinery is operating at full power, the throttle response is agile and the power delivery is continuous, completely eliminating the intermittent power drops and annoying surges caused by the inability to establish rail pressure. With its excellent resistance to oil wear and precise SCV valve flow control, it significantly reduces exhaust smoke, making it the ideal choice for ensuring efficient operation and long-term cost reduction for heavy-duty vehicle fleets.

• Direct Supply from Our Own Manufacturing Plant, Eliminating Multiple Intermediary Price Markups: Addressing the predicament of high prices for original equipment manufacturer (OEM) power components for heavy-duty commercial vehicles and the markups from multinational distribution channels, we adopt a direct sales model from our own factory. This not only effectively breaks down channel premiums, allowing you to obtain high-quality parts with a more reasonable budget, but also provides direct OEM-level technical support, significantly reducing your company's operating and maintenance expenses.
• Normalized Large-Scale Spot Warehousing, Cutting Off Long Waiting Times for Parts: When heavy-duty transportation and port operations machinery are grounded due to oil pump failure, it incurs huge daily downtime costs and default risks. We have established a dedicated finished product inventory plan for this model, ensuring ample stock year-round. Once an order is finalized, it can be immediately packaged with multiple layers of protective material and shipped out, providing extremely rapid logistics response to ensure your vehicle returns to the track as quickly as possible.
• 100% Fully Simulated Digital Bench Inspection, Eliminating Early Component Failures: Addressing the common problems of inferior oil pumps such as plunger jamming, high-pressure internal leakage, and SCV valve control malfunction, each of our high-pressure oil pumps undergoes extreme pressure and simulated load testing on a high-precision automated testing bench before leaving the factory. 100% coverage of pressure stability and oil return volume testing across the entire speed range ensures that every product delivered to you possesses extremely high quality consistency and a long service life.

• Intercity Heavy-Duty Trunk Logistics and Earthwork Transportation: On long-distance inter-provincial highways and complex mining routes, Hino 700 dump trucks equipped with P11C engines are fully loaded with tens of tons of ore and climbing steep inclines. Facing steep slopes and heavy loads, the driver frequently shifts gears and presses the accelerator hard. The 094000-0551 high-pressure oil pump precisely adjusts the internal oil intake through the SCV valve, maintaining extremely high and stable common rail pressure. This ensures the truck maintains strong power and linear acceleration under low speed and heavy load conditions, preventing stalling and engine failure mid-journey.
• Port Specialized Operations and 24/7 Heavy-Duty Lifting: At busy container terminals with massive throughput, port cranes and specialized heavy-duty handling machinery equipped with heavy-duty diesel engines are continuously performing grabbing and stacking operations around the clock. With frequent and dramatic changes in lifting tonnage, engine load fluctuates rapidly. High-pressure oil pumps, with their excellent rail pressure build-up speed and highly sensitive flow feedback, ensure stable generator or transmission system speeds, effectively avoiding robotic arm swaying caused by power output drift, achieving excellent fuel economy while ensuring operational safety.
