Product Introduction

372-1307010 Vehicle-specific Corrosion-proof Optimized cooling Water Pump for Chery QQ QQ3

Professional automotive water pumps are core components of the engine cooling system. They drive the circulation of coolant through centrifugal force to precisely regulate the operating temperature. Certified by the ISO/TS 16949 automotive quality system and compliant with the DIN EN 1151 standard, they have passed a 500-hour continuous operation test without failures. Adopting high-wear-resistant bearings and precision sealing technology, their leakage rate is ≤ 10⁻⁶ mbar·L/s, and they can maintain a service life of 8-10 years under normal use. Rigorous craftsmanship ensures corrosion resistance and damage prevention, providing reliable temperature control support for the efficient operation of the engine.

Product Advantage

1. Authoritative Certification & Rigorous Testing:

   This automotive water pump has obtained ISO/TS 16949 automotive industry quality system certification and complies with the DIN EN 1151 standard for cooling system components. Before leaving the factory, it undergoes a 500-hour continuous operation test, with the failure rate controlled within 0.1%. It also passes extreme temperature cycle tests from -40℃ to 120℃, ensuring stable operation under complex working conditions and providing customers with reliable products that meet international standards.

2. High-Wear-Resistant Bearings & Precision Sealing Technology:

   It adopts imported high-wear-resistant bearings, which still maintain excellent performance after 3 million cycles of friction testing, significantly reducing operating noise (≤55dB). Equipped with a multi-layer composite precision sealing structure, the leakage rate is strictly controlled at ≤10⁻⁶ mbar·L/s, far lower than the industry average standard of 10⁻⁵ mbar·L/s. This effectively prevents engine overheating caused by coolant leakage and extends the overall service life of the high-durability engine water pump.

3. High-Strength Materials & Anti-Corrosion Design:

   The pump body is made of high-strength cast iron, showing no rust traces after 500 hours of salt spray testing, with corrosion resistance 40% higher than that of ordinary cast iron. The impeller is made of glass fiber-reinforced nylon, with a tensile strength of 85MPa, which can withstand the centrifugal impact during high-speed operation. Under normal usage scenarios, its service life can reach 8-10 years, 2-3 years longer than the industry average, reducing the frequency and cost of customer replacements.

4. Precise Adaptation & Comprehensive After-Sales Service:

   As a professional engine cooling system water pump, its installation dimension error is ≤0.1mm, compatible with a variety of mainstream engine cooling systems, and can be adapted without additional modifications. At the same time, it provides a 1-year warranty service. If customers encounter quality problems during use, they can enjoy after-sales support with response within 24 hours and replacement delivery within 48 hours. Up to now, the customer after-sales satisfaction rate has reached 98.5%, and we have accumulated more than 1,000 long-term overseas cooperative customer cases.

Technical Parameters

Product Uses

Here are specific application scenarios of Water Pump:

1. Daily Urban Commuting Scenario:

   Suitable for urban driving with frequent start-stops, the automotive water pump maintains stable operation in environments with large temperature differences between morning and evening, thanks to its wide temperature resistance range of -40℃~180℃. Verified by a 500-hour continuous test, it can meet the cooling needs of 1-2 hours of short-distance driving per day. Compliant with the DIN EN 1151 standard, it avoids poor coolant circulation caused by frequent start-stops.

2. Commercial Light Transport Scenario:

   For light transport vehicles operating under long-term high loads, this water pump has a rated flow rate of 120L/min at 4500rpm, which quickly dissipates engine heat. Equipped with a corrosion-resistant pump body (no rust after 500-hour salt spray test), it supports 8-10 hours of daily transport work, reducing the risk of failures caused by overheating, with a post-sales failure feedback rate of less than 0.1%.

3. Extreme Climate Usage Scenario:

   In areas with high-temperature exposure (ambient temperature ≥35℃) or extreme cold (≤-20℃), the water pump has passed 100 temperature cycle tests (performance attenuation ≤5%). Its multi-layer sealing structure (leakage rate ≤10⁻⁶ mbar·L/s) prevents high-temperature leakage or low-temperature cracking. Compliant with strict ISO/TS 16949 requirements, it adapts to engine cooling needs in complex climates.

4. Professional Maintenance & Replacement Scenario:

   As a preferred engine cooling system water pump in the maintenance market, it has an installation dimension tolerance of ≤0.1mm and can be quickly replaced without additional modifications. Relying on a 1-year warranty and 24-hour after-sales response (98.5% customer satisfaction), it has served over 1,000 global maintenance providers, becoming a reliable choice for efficient maintenance.

Product Operate Guide

Before installation, check the pump’s seal (ensure no damage, in line with ISO/TS 16949 standards). Tighten mounting bolts to 25-30 N·m (avoid over-tightening). After installation, add coolant as required, then run the engine for 5 mins to check for leaks. Inspect the pump every 6 months; replace seals if leakage exceeds 10⁻⁶ mbar·L/s to maintain efficiency.
