Bomba de urea
The OEM Urea Pump 612640130088 is a precision-engineered fluid delivery component manufactured exclusively for the Shacman X5000 heavy-duty truck platform. This critical pump is the heart of the Selective Catalytic Reduction system, drawing Diesel Exhaust Fluid from the onboard storage tank and delivering it at precisely controlled pressure to the dosing module, which injects a fine mist of DEF into the exhaust stream to chemically convert harmful nitrogen oxide emissions into harmless nitrogen and water vapor, ensuring the vehicle meets stringent environmental regulations.
Constructed with a high-efficiency electric motor, precision diaphragm or gear pumping elements, and integrated pressure and temperature sensors, the urea pump delivers exceptional dosing accuracy, freeze-thaw durability, and long-term reliability under the continuous duty cycles and harsh under-chassis environment of heavy-duty truck operation. The 612640130088 part features an integrated control module that communicates with the engine ECU, enabling precise DEF metering based on real-time engine operating conditions and exhaust NOx levels.
Installing a genuine OEM urea pump preserves the designed emissions control performance and prevents the SCR system faults that can lead to engine derate, increased fuel consumption, and costly downtime. The 612640130088 identifier provides complete traceability to Shacman’s rigorous material specifications and precision manufacturing quality assurance standards for this environmentally critical emissions control component.

The pump maintains the exact DEF pressure required by the dosing injector to produce a fine, atomized spray, ensuring the urea solution mixes thoroughly with exhaust gases for maximum NOx conversion efficiency in the SCR catalyst.
The 612640130088 pump’s integrated heating system and robust internal components withstand the repeated freeze-thaw cycles that occur when DEF crystallizes at sub-zero temperatures, ensuring reliable operation in all climate conditions.
The pump’s integrated control module adjusts DEF flow based on engine load, exhaust temperature, and NOx sensor feedback, optimizing emissions reduction while minimizing DEF consumption and preventing ammonia slip from overdosing.
The urea pump 612640130088 is typically mounted within or adjacent to the DEF tank assembly on the Shacman X5000 vehicle, forming part of the integrated DEF supply module. Before installation, all DEF fluid connections must be clean and free of any contamination or crystallized urea deposits. The pump is positioned and secured with its mounting fasteners torqued to specification. The DEF suction and pressure lines are connected, ensuring all quick-connect fittings are fully engaged and locked. The electrical connectors for the pump motor, pressure sensor, temperature sensor, and heating element are engaged and locked. After installation, the SCR system must be primed and leak-tested using the appropriate diagnostic scan tool to purge air from the lines and verify correct system pressure. The DEF dosing function should be verified by monitoring NOx conversion efficiency and DEF pressure during a road test or stationary regeneration cycle.
Each urea pump produced under OEM number 612640130088 is assembled from precision-manufactured components in a clean-room environment to prevent contamination of the sensitive internal passages. The pump housing is molded from chemical-resistant engineering plastics or cast from corrosion-resistant metals that withstand the mildly corrosive nature of DEF fluid. The electric motor is wound with high-temperature rated wire and fitted with sealed bearings. The pumping elements, whether diaphragm or gear-type, are machined to micron-level tolerances to deliver the precise and consistent flow rates required for accurate DEF metering.
The integrated pressure and temperature sensors are calibrated against certified reference standards. The electronic control module is programmed and tested to ensure correct communication with the vehicle’s engine ECU. Each completed pump assembly undergoes a comprehensive functional test on a dedicated test stand. This testing verifies flow rate at specified pressures, sensor accuracy, heating element function, and communication protocol integrity. The pump is then sealed in protective packaging with all ports capped to prevent contamination, and labeled with the 612640130088 part number for complete traceability.
The urea pump should be inspected if the vehicle displays SCR-related diagnostic trouble codes, if there is visible DEF crystallization around the pump or connections, or if the engine exhibits derate or poor NOx conversion efficiency. A diagnostic scan tool can be used to monitor pump pressure, motor current draw, and sensor readings to help determine if the pump is functioning within specification. Abnormal pump noise or a pump that fails to build pressure are clear indicators of internal failure.
If the urea pump is diagnosed as faulty, it must be replaced with a new 612640130088 component. When replacing the pump, it is essential to use only high-quality DEF that meets ISO 22241 specifications, as contaminated or off-specification DEF is a leading cause of pump and injector failure. The DEF tank should be drained and flushed if contamination is suspected. After pump replacement, the SCR system must be primed and the DEF pressure verified using a diagnostic scan tool before the vehicle is returned to service. Prompt repair of SCR system faults prevents the engine derate that limits vehicle performance and can leave a driver stranded far from service facilities.

Choosing the genuine Urea Pump 612640130088 is a decision that directly impacts the emissions compliance and operational availability of your Shacman X5000 vehicle. Aftermarket urea pumps manufactured with inferior sensors, imprecise pumping elements, or inadequate freeze protection can fail to deliver the correct DEF pressure and flow rate, causing the SCR system to operate inefficiently. This triggers NOx sensor fault codes that can lead to engine derate, reducing vehicle power and speed, and ultimately forcing the driver to seek immediate service to restore full engine performance.
The OEM urea pump’s specific pressure and flow characteristics, sensor calibration, freeze protection strategy, and ECU communication protocol were validated through extensive cold chamber testing, hot climate testing, and accelerated durability testing. Shacman engineers specified this exact pump design to provide the precise DEF metering that the X5000’s SCR system requires to meet its certified NOx emissions levels. The 612640130088 pump delivers the dependable emissions control performance that keeps the vehicle compliant with environmental regulations and operating at full power without interruption.
Professional fleet technicians and maintenance managers worldwide standardize on the 612640130088 urea pump for its guaranteed sensor accuracy, precise flow delivery, and proven freeze-thaw durability in the field. This precision fluid handling component is the heart of the SCR system that allows the engine to produce its full rated power while meeting strict emissions standards. Trust only the urea pump that Shacman engineered and certified for the demanding X5000 heavy truck platform.
The urea pump 612640130088 handles Diesel Exhaust Fluid, a solution of approximately 32.5 percent high-purity urea in deionized water. DEF is a mildly corrosive fluid that can crystallize when exposed to air, forming white deposits that can clog small passages and damage pump components. The OEM pump is specifically designed with materials and internal coatings that resist this corrosion and crystallization, and its sealed design prevents the air exposure that leads to deposit formation when the system is idle.
Proper DEF quality and handling are essential for maximizing urea pump life. DEF should be stored in sealed containers away from direct sunlight and extreme temperatures, as UV exposure and heat can degrade the urea solution. The DEF tank should not be overfilled, and any DEF spilled on the vehicle or pump should be rinsed with water, as the crystallized residue can attract moisture and cause corrosion. Using only ISO 22241 certified DEF from reputable suppliers is one of the most effective ways to protect the SCR system components from premature failure.
For our international customers, we take exceptional care in packaging the 612640130088 urea pump to prevent any contamination or damage during global transit and extended storage.
