2. Premium Material Selection & Precision Manufacturing Process

The Chery 484FC-1307010BA water pump is crafted from high-performance, automotive-grade materials, carefully selected by Chery’s engineering team to withstand the extreme operating conditions of the Chery Tiggo’s cooling system—including high temperatures (up to 120°C), high system pressure (up to 1.2 bar), and constant exposure to coolant and mechanical stress. Drawing on years of experience in automotive powertrain component manufacturing and advanced material science, Chery prioritizes materials that balance heat resistance, corrosion resistance, wear resistance, and mechanical strength, ensuring the water pump maintains stable performance over a service life of typically 100,000–150,000 kilometers under normal operating conditions.

The main body (pump housing) of the 484FC-1307010BA water pump is made of high-quality aluminum alloy (ADC12), a material widely recognized in the automotive industry for its excellent heat conductivity, lightweight properties, and corrosion resistance. Aluminum alloy is chosen for its ability to efficiently dissipate heat generated during operation, reducing the risk of overheating and extending the pump’s service life. Additionally, the lightweight nature of aluminum alloy helps reduce the overall weight of the engine, contributing to improved fuel efficiency—a key consideration for the Chery Tiggo’s practical design.

The impeller, the core rotating component responsible for generating coolant flow, is made of high-grade engineering plastic (PA66+GF30), reinforced with 30% glass fiber to enhance its mechanical strength, wear resistance, and dimensional stability. This material combination ensures the impeller can withstand high rotational speeds (up to 6,000 RPM) and constant contact with coolant without deformation, cracking, or wear. The impeller’s design is optimized for maximum fluid dynamics, ensuring efficient coolant circulation with minimal energy loss.

At the heart of the 484FC-1307010BA water pump is a high-precision ball bearing, made of high-quality bearing steel (GCr15), which ensures smooth rotation and minimal friction. The bearing is sealed with a double-lip oil seal and a mechanical seal, both made of high-temperature-resistant EPDM (Ethylene Propylene Diene Monomer) rubber and carbon-graphite materials. This dual-seal design prevents coolant leakage and lubricant loss, ensuring the bearing remains protected and operates smoothly even under extreme conditions. The mechanical seal, in particular, is critical for preventing coolant seepage, which can lead to engine damage and water pump failure.

The manufacturing process of the 484FC-1307010BA water pump follows a strict, ISO 9001 and IATF 16949 certified production workflow, consistent with Chery’s global quality standards and modern automotive water pump manufacturing practices.
