Verification Tip: Cross-reference your vehicle’s VIN or engine code with our technical team for 100% fitment confirmation.

• Material: High-strength aluminum constructionprovides exceptional resistance to corrosion and thermal expansion, while withstanding torsional forces up to 373 N·m—the maximum torque output of the 4M51 engine .

• Surface Treatment: Precision-machined internal components with anti-wear coatings reduce friction, extending service life beyond 150,000 km under typical commercial use.

• Leak-Proof Design: Reinforced O-ring seals and pressure-tested housing eliminate hydraulic fluid leakage, a common failure point in generic pumps.

• On-Demand Pressure Delivery: Optimized impeller design generates consistent hydraulic flow (10-15 L/min) at operating pressures up to 140 bar , ensuring light, responsive steering even when navigating tight loading docks or congested urban roads.

• Engine Sync Technology: Seamlessly integrates with the 4M51’s DOHC valve train , maintaining stable performance across engine speeds (1600-3200 RPM) without power lag.

• Temperature Resilience: Advanced oil passages dissipate heat efficiently, keeping operating temperatures below 85°C to prevent fluid degradation .

• OEM-Matched Dimensions: Exact replication of mounting points and connection interfaces allows drop-in replacement—no modifications required, reducing repair time by up to 50% compared to universal alternatives .

• Service-Friendly Design: Accessible pressure relief valve and fluid ports simplify routine inspections, aligning with Fuso Canter’s maintenance protocols.

• Production Process: CNC-machined components and automated assembly ensure dimensional accuracy within ±0.02mm , exceeding industry standards for hydraulic pumps.

• Triple-QC Protocol: Each unit undergoes: ① raw material composition testing, ② dynamic performance simulation (mimicking 10,000 km of use) , and ③ final pressure leak testing.

• Warranty Coverage: 12-month manufacturer warrantycovering defects in materials and workmanship, with dedicated technical support for commercial fleet operators.
