The WG9925561039 Urea Pump Filter is a critical component in the Selective Catalytic Reduction (SCR) system of SINOTRUK Sitrak heavy‑duty trucks. It is installed at the inlet of the urea pump to remove contaminants from the AdBlue/DEF fluid before it is pressurised and injected into the exhaust stream. Clean urea is essential for maintaining the efficiency of the SCR catalyst and ensuring compliance with Euro 4, Euro 5, and Euro 6 emission standards. A clogged or degraded filter can lead to reduced pump performance, injector blockage, and increased NOx emissions.
Manufactured from high‑grade synthetic filtration media with a micro‑porous structure, the WG9925561039 filter effectively traps particles down to 10 micrometres, including dust, crystals, and other debris that may be present in the urea solution. The robust plastic housing and nitrile seals are specifically formulated to resist the corrosive nature of urea and withstand temperature variations from -40°C to +85°C, ensuring reliable operation in all climates. This genuine OEM filter is a direct replacement for the original factory part, guaranteeing a perfect fit and restoring the SCR system’s full protection.
Regular replacement of the urea pump filter is essential for preventing costly repairs to the urea pump and injector. The WG9925561039 filter eliminates the risk of contamination‑related failures, ensuring that your SITRAK C7H truck continues to meet emission regulations while maintaining optimal fuel economy and engine performance.
The WG9925561039 filter uses a micro‑porous synthetic medium that captures particles as small as 10 μm, effectively protecting the urea pump and injector from abrasive wear and clogging.
Constructed from corrosion‑resistant plastic and nitrile rubber, the WG9925561039 filter withstands the aggressive chemical nature of urea solution, ensuring long‑term durability without swelling or degradation.
The filter’s internal geometry is designed to minimise pressure drop while maximising contaminant holding capacity, ensuring that the urea pump receives a steady, unrestricted flow of clean fluid.
Designed as a direct OEM replacement, the WG9925561039 filter comes with pre‑fitted seals and requires no special tools for installation, reducing service time and simplifying maintenance.
Protects SCR Components: The WG9925561039 filter prevents contaminants from reaching the urea pump and injector, significantly extending their service life and reducing the risk of expensive repairs.
Maintains Emission Compliance: A clean urea supply ensures that the SCR system operates at peak efficiency, keeping NOx emissions within legal limits and avoiding fines or failed inspections.
Prevents Crystallisation Issues: The filter’s urea‑compatible material and fine filtration reduce the formation of crystals that can block the pump and lines, ensuring reliable system operation.
Cost‑Effective Maintenance: Regular replacement of the WG9925561039 filter is a low‑cost preventive measure that avoids downtime and expensive repairs associated with SCR system failures.
OEM Quality Assurance: The WG9925561039 filter meets SINOTRUK’s original equipment specifications, guaranteeing a perfect fit and reliable performance that matches the original factory part.
Wide Compatibility: This filter is compatible with a broad range of SINOTRUK trucks, including SITRAK C7H, C5H, HOWO T7H, T5G, and A7, simplifying inventory management for fleet operators.
Compatible Models:
The WG9925561039 filter is a direct cross‑reference for multiple OEM part numbers, ensuring broad applicability across the SINOTRUK truck range. Always verify compatibility using your vehicle’s VIN or existing filter part number.
Installation Tips & Best Practices:
The WG9925561039 urea pump filter is produced using high‑precision injection moulding and advanced filtration media assembly techniques. The housing is manufactured from glass‑fibre‑reinforced polyamide (PA66+GF) that offers excellent mechanical strength, dimensional stability, and resistance to urea and temperature cycling. The filtration medium is a multi‑layer synthetic fibre matrix with a micro‑porous structure that provides high particle capture efficiency while maintaining low flow resistance.
Each WG9925561039 filter undergoes stringent quality testing, including flow rate verification, burst pressure testing, and particle retention efficiency measurements. The seals are tested for urea compatibility and leakage at extreme temperatures. The filter is also validated for resistance to crystallisation and chemical degradation, ensuring long‑term reliability in the harsh environment of the SCR system.
The manufacturing process adheres to ISO 9001 and IATF 16949 standards, guaranteeing that every WG9925561039 filter meets the demanding quality requirements of SINOTRUK’s original equipment. This ensures that you receive a product that performs exactly as the factory‑fitted component, providing consistent protection for your truck’s SCR system.
The WG9925561039 Urea Pump Filter from SINOTRUK Sitrak is the definitive choice for fleet operators and owner‑drivers who demand reliable SCR system protection, emission compliance, and long‑term durability. As a genuine OEM‑grade component, it guarantees a perfect fit, consistent filtration performance, and peace of mind—backed by SINOTRUK’s engineering excellence and decades of experience in heavy commercial vehicle manufacturing.
Whether you are performing routine maintenance on a high‑mileage fleet truck or servicing a SITRAK C7H, the WG9925561039 filter delivers the performance and reliability you need to keep your SCR system operating at peak efficiency.
