Our GLL ADC12 aluminum alloy water pump has lightweight design, efficient thermal management and high reliability. It not only meets the upgrade needs of traditional fuel vehicles, but also provides key support for new energy power systems. It is becoming the preferred solution for OEMs and the aftermarket.
Our GLL water pump adopts modular design, integrating dual coolant inlets and adjustable valve devices. This structure realizes stepless adjustment of the operating point through a translational valve piston: under low load conditions, the spring device preloads the valve body to close the secondary inlet, reducing power consumption; under high load, the valve body opens the primary and secondary inlets at the same time, and the flow rate is increased by 40%. This design reduces the energy consumption of the water pump by 25% and increases the response speed by 30%, which is especially suitable for frequent start-stop scenarios in urban conditions.
Our GLL water pump has passed ISO/TS 16949 quality system certification, and the key process adopts the German DMG MORI five-axis machining center. The shell flatness is controlled within 0.02mm, and the dynamic balance accuracy reaches G2.5 level. The sealing system adopts a combination of fluororubber + ceramic coating, which maintains zero leakage in the temperature range of -40℃ to 180℃. The life test shows that the sealing performance attenuation rate is less than 5% after 2000 hours of continuous operation.
Our GLL adapts the ADC12 aluminum alloy in is an aluminum-based die-casting material with excellent casting performance, thermal conductivity and corrosion resistance. Its main features include:
Good fluidity: suitable for mold filling of complex structures, ensuring that the water pump housing is integrally formed and has a strong structure.
Excellent mechanical strength: ensures stable operation under high temperature and high pressure environment.
Excellent corrosion resistance: GLL ADC12 aluminum alloye can ffectively resists chemical corrosion in coolant and prolongs service life.
Lightweight advantage: lighter than traditional cast iron materials, which helps reduce vehicle weight and improve fuel economy.
In turbocharged engines, the optimized impeller design increases the coolant flow rate by 18%, and with high thermal conductivity materials, effectively reduces the temperature of the turbocharger bearing. Actual test data from a mainstream car company shows that models equipped with GLL water pumps reduce cooling system energy consumption by 19% under NEDC cycle conditions, and the engine water temperature fluctuation range is reduced to ±2°C, directly improving fuel economy by 3.2%.
