Dosing Pump Cummins 2871880 | A028Y793

High-Precision DEF Dosing Pump for Cummins Engines

The Cummins 2871880 Dosing Pump is a critical component of the Selective Catalytic Reduction (SCR) system in modern heavy-duty diesel engines. This pump is engineered to precisely deliver Diesel Exhaust Fluid (DEF) into the exhaust stream, where it reacts with nitrogen oxides (NOx) to convert them into harmless nitrogen and water vapor. By maintaining exact dosing levels, this component ensures your vehicle meets stringent emissions regulations without sacrificing engine performance.

Key Features and Benefits

• Precise Fluid Delivery: Ensures the exact amount of DEF is injected based on real-time engine data from the ECU.
• Corrosion-Resistant Construction: Manufactured with high-quality materials specifically designed to withstand the corrosive properties of AdBlue/DEF.
• System Efficiency: Optimizes the chemical reaction within the SCR catalyst, preventing “DEF crystallization” and maintaining fuel efficiency.
• Robust Design: Built to endure the harsh operating conditions of commercial trucking and industrial applications.
