Volvo urea pump 21574975 plays an "environmental core" role in the emission reduction system of diesel vehicles. The SCR system precisely sprays urea solution into the exhaust through it, reducing nitrogen oxide emissions through chemical reactions. If the injection amount of the pump body deviates or is blocked, it will cause emissions to exceed the standard, engine torque to be limited, and even trigger fault lights affecting the road. Especially in areas with strict environmental regulations, the stable operation of urea pumps is directly related to the compliance of equipment operation.
This urea pump adopts a composite structure of engineering plastics and stainless steel. The inner wall of the pump chamber is treated with a PTFE coating, which is resistant to corrosion from urea solution and low-temperature crystallization. Its service life is extended by 35% compared to ordinary pump bodies. Built in high-precision flow sensor and variable frequency motor can adjust the injection amount in real time according to the exhaust concentration, with an error controlled within ± 2%, ensuring maximum urea utilization and avoiding waste or shortage.
To prevent blockage, the pump body is designed with a self-cleaning function, which automatically clears residual urea in the pipeline after shutdown, and works with a large-diameter filter to intercept impurities and reduce the risk of nozzle blockage. The SCR system is compatible with Volvo FH, FM series trucks and FMX engineering vehicles, and can be replaced without modification. After installation, it can quickly restore emission reduction function and meet the National VI and Euro VI emission standards.
Ningbo Qiuning Trading Co., Ltd. provides original and auxiliary factory options for this model of urea pump. The original factory products strictly follow Volvo's production standards, and the injection logic is perfectly matched with the original vehicle ECU, suitable for scenarios with extremely high emission accuracy requirements; By optimizing the flow channel design of the pump body, the subsidiary products offer better cost-effectiveness while ensuring injection accuracy, meeting routine maintenance needs.
Each batch of products in the company has undergone urea cycle testing and corrosion resistance verification to ensure no leakage or jamming. A professional team can recommend suitable products based on the operating area of the vehicle (such as low-temperature areas that require emphasis on antifreeze design), and provide guidance on system matching after installation. No matter which one is chosen, it can provide reliable emission reduction guarantees for Volvo vehicles, avoiding environmental penalties and power limitations.
