company news about Why are AdBlue pumps so expensive?

The high price of AdBlue (diesel exhaust fluid) pumps is mainly caused by the following factors:

1. Technical complexity and production standards
Precision manufacturing requirements
AdBlue pumps need to work with the SCR (selective catalytic reduction) system, and the injection accuracy directly affects the nitrogen oxide conversion efficiency. The pump body needs to withstand the corrosiveness of urea solution and meet the stability in high-temperature exhaust environments. The manufacturing process involves high-precision sensors and corrosion-resistant materials.
Environmental protection regulations adaptation
In order to meet strict emission standards (such as Euro VI), the design of the pump needs to pass a complex certification process, and the R&D and testing costs are high.
2. Material and supply chain pressure
Special material cost
AdBlue contains 32.5% urea solution, which is in long-term contact with corrosive ordinary metals. The pump body needs to use stainless steel or polymer composite materials, and the raw material and production costs are significantly increased.
Influence of supply chain fluctuations
In recent years, the export restrictions on AdBlue urea in some regions have led to tight market supply, which has also affected the production capacity and logistics costs of related accessories (such as pumps).
3. Market and brand factors
Brand technology monopoly
Mainstream automakers usually specify accessories from original or certified suppliers. Technical barriers make third-party alternatives less and price competition limited.
After-sales maintenance cost transmission
Poor quality AdBlue or pump failure may damage the SCR system and increase repair costs. Therefore, the premium of high-reliability pumps partially reflects the risk aversion cost.
4. Specific use scenarios
AdBlue pumps need to be deeply integrated with the vehicle's electronic control system, and customized development further increases costs. Compared with ordinary fuel pumps, their application scenarios are more complex, maintenance frequency is lower, and the cost per unit is higher.
