As the core component of the hydraulic steering system, the power steering pump for small cars has passed ISO 9001 certification and complies with QC/T 299-2000 standard. Built in flow control valve and pressure safety valve can reduce steering resistance and prevent system overload, with a noise level of ≤ 80dB. The average lifespan is 8-10 years/150000 kilometers, suitable for 95% of mainstream car models, and undergoes 100% performance testing before leaving the factory to ensure stable operation in environments ranging from -40 ℃ to 120 ℃.
Our electric power steering pump (EPS) uses an efficient permanent magnet synchronous motor, with significantly higher energy conversion efficiency than traditional hydraulic pumps. Actual test data shows that under standard operating conditions (600r/min, 7.5MPa), its efficiency can reach over 80%, effectively reducing the overall energy consumption of the vehicle and helping to extend the range of electric vehicles. The pump body adopts lightweight design and environmentally friendly materials, which not only reduces its own weight, but also reflects our high standards for sustainable development. Its low energy consumption characteristics (operating current<5.5A) are particularly suitable for the needs of modern energy-saving and environmentally friendly vehicles.
This power steering pump has undergone rigorous reliability testing and road testing, including 30000 kilometers on buses and 50000 kilometers on trucks, proving its long service life and stable performance output. The product uses high-performance alloys and composite materials to enhance the corrosion resistance, wear resistance, and durability of the pump body. Its wide speed range design (500-3500r/min, some models can reach 8000r/min) ensures that the engine can receive stable and continuous steering assistance at various speeds, with impeccable reliability.
Some high-end models innovatively adopt high and low voltage dual winding motors and dual controller designs, forming a dual drive power source. When the high-voltage drive system unexpectedly fails, the low-voltage system can start working instantly without delay (obtained national invention patent ZL201511002880.7, etc.), ensuring continuous provision of steering assistance, greatly improving driving safety and system reliability, and avoiding the risk of steering failure at critical moments. This unique technology is also in a leading position in the international market.
We have optimized the pump body structure (such as using unequal slot design) and advanced manufacturing processes to deviate the natural frequency of the pump body from its fundamental frequency of rotation, effectively avoiding the resonance frequency exclusion zone. This ensures that the noise of the steering pump is controlled below 72dB during operation (even at 1000r/min, 7.5MPa), and some models can achieve excellent quietness below 48dB, providing you with a quieter and more comfortable cockpit environment, bidding farewell to the noisy noise of traditional steering pumps.
Our power steering pump is not just a mechanical component, but also a part of the intelligent automotive system. It has the potential for deep integration with vehicle ADAS (Advanced Driver Assistance Systems) and can support future implementation of more advanced functions such as lane keeping assistance. The product line is rich, with displacement covering various specifications from 8.5ml/r to 20ml/r, widely compatible with a variety of domestic car models, providing precise matching and easy installation.

Here are specific application scenarios of Brake Drum:
The product is designed according to QC/T 299.1-2014 standard for frequent lane changes and low-speed turning during peak hours in the morning and evening. With a stable working pressure of 10-14MPa, it can reduce steering resistance by 30%, avoiding arm fatigue caused by frequent operation by car owners. It is suitable for 95% of mainstream family sedans and achieves a light steering feel on congested roads.
When operating continuously at high speeds (500-6000RPM adaptation range), the flow control system tested by ISO 14829-1 can stably output 8-12L/min hydraulic oil, ensuring steering accuracy during 120km/h cruising lane change, and noise at a distance of 1 meter is ≤ 80dB, which does not interfere with the quietness of the car and meets the comfort requirements for long-distance driving.
In the face of continuous and high-frequency turning on mountain roads, the product has passed the VDA 231-100 reliability test (150 hours of continuous operation without faults). The high-strength cast iron pump body can withstand frequent pressure fluctuations (within ± 0.5MPa), avoiding the impact of steering system lag on handling safety, and is suitable for the mountain driving needs of various vehicle models such as SUVs and sedans.
In cold regions with a temperature of -40 ℃, the product meets the QC/T 299.1 environmental adaptability standard, with a low-temperature start-up success rate of over 98%. The engineering resin impeller is resistant to low-temperature embrittlement and can quickly establish steering pressure, solving the problem of heavy steering for cold vehicles in winter and ensuring low-temperature travel safety.
For vehicles that have been driven for more than 8 years and have aging steering pumps, the product has passed IATF 16949 certification. After replacement, the average service life reaches 8-10 years (equivalent to the service life of new car parts), without frequent maintenance, suitable for mainstream brand old models, and reduces maintenance costs for car owners.
For a smooth installation, first, disconnect the battery. Drain the old power steering fluid and safely remove the old pump. Our pump is designed for a precise OE-fit, making installation straightforward. Use only the recommended ATF or specific power steering fluid (check your vehicle's manual) to prevent damage. After installation, bleed the system thoroughly by turning the steering wheel lock-to-lock several times with the front wheels off the ground to remove air bubbles. Check for leaks. Properly installed and maintained, our high-performance pump ensures quiet operation (<72dB) and delivers reliable pressure (e.g., 7.5MPa) for a smooth steering feel. Enjoy enhanced driving safety and comfort.
