Fuel Injection Pump 2128559 10R-7652 212-8559 Compatible with Caterpillar CAT Excavator 320C 321C 320D 323DLN Engine 3066
Generic 1. OEM-level performance and precise fuel injection: Utilizing high-pressure direct injection technology (2000-3000 PSI operating pressure), this engine matches the ECU's fuel curve to ensure fuel atomization comparable to OEM fuel. An internal precision plunger assembly achieves a flow rate error of ≤3%, improving combustion efficiency, reducing fuel consumption and emissions, and boosting power response by 15%. || 2. Premium Materials, Ultra-Long Service Life Pump Body: CNC-machined aircraft aluminum alloy, corrosion resistance five times greater than ordinary materials Key Components: Imported German bearings + ceramic plunger, 800-hour endurance test-passed Sealing System: Viton fluoroelastomer seals, resistant to ethanol gasoline and extreme temperatures || 3. Intelligent Diagnosis, Plug-and-Play Installation Built-in pressure sensor self-calibration system, compatible with OBDII diagnostics Included installation and positioning fixture, 90% of vehicle models can be replaced DIY in less than 30 minutes || 4. Triple Noise Reduction Design, Quiet Operation First Layer: Hydraulic shock valve reduces pressure pulses Second Layer: Noise-absorbing composite housing Third Layer: Optimized gear transmission structure, operating noise ≤65dB || 5. Five-Year Warranty, Professional Technical Support: This is an industry-leading five-year warranty and comes with a complimentary fuel system cleaner. Expert hotline guidance is available to troubleshoot issues such as "difficult cold start" and "low high-pressure rail pressure." Return and exchange services are available with inspection reports.
