Product Introduction
A11-3407020 Responsive Trusted Thermo-stable Power Steering Pump for Chery
Our Steering Pump for Chery is a core component of the power steering system, engineered with 18 years of auto parts expertise. It delivers stable hydraulic pressure to enable light, smooth steering, cutting driver effort by 60% vs. manual steering.
Every unit undergoes 3-stage QC (component, assembly, performance tests) in our ISO 9001-certified factory, boasting a 99.3% pass rate—surpassing the industry’s 96% average. With a service life of over 300,000 km under normal use, it ensures reliable performance for daily commutes and long-haul trips alike.
Product Advantage
1. Intelligent Hydraulic Boost System for Precise Control
Equipped with a self-developed variable-displacement hydraulic valve, our Chery steering pump adjusts oil pressure (0-14MPa) in 0.2 seconds based on steering speed. This ensures 95%+ power transmission efficiency, making steering 60% lighter at low speeds while maintaining stability at high speeds. Backed by 18 years of R&D, the system passed 15,000+ cycle tests (SAE J2179 standard).
2. Strict Quality Inspection with Industry-Leading Reliability
Every unit undergoes 3-stage QC (component precision testing, assembly calibration, end-of-line performance verification) in our ISO 9001 & IATF 16949-certified factory. The final pass rate has stayed at 99.3% for 5 consecutive years—3.3% higher than the industry average (96%). This guarantees zero-defect delivery of each high-performance Chery steering pump.
3. High-Wear Materials Extend Service Life by 50%
The pump’s rotor uses 42CrMo alloy steel (hardness: HRC 38-42) and the oil seal adopts ceramic-coated NBR material. These reduce friction by 45% vs. standard parts and resist -40℃ to 120℃ extreme temperatures. Real-road data shows it maintains stable performance for over 300,000 km, doubling the lifespan of ordinary steering pumps for Chery.
4. Energy-Saving Design Cuts Fuel Consumption
Integrated with an intelligent power-saving valve, the pump reduces unnecessary oil flow by 20% when steering is idle. Tested on dynamometers, this design lowers vehicle fuel consumption by 0.4-0.6 L/100km (EU ECE R122 standard). For fleet operators, it saves 800-1200 L of fuel annually per vehicle—an economical upgrade for Chery power steering pumps.
5. Plug-and-Play Installation Saves Maintenance Time
With 1:1 dimensional matching to original Chery parts, the pump requires no modifications. Pre-assembled oil pipes and standardized connectors shorten installation to 25 minutes—65% faster than non-customized alternatives. We also provide bilingual (English/Spanish) manuals and 24/7 technical support, ensuring hassle-free replacement of your Chery steering system pump.

Product Uses
Here are specific application scenarios of Power Steering Pump:
1. Daily Urban Commuting
Ideal for 5-60km daily trips with frequent stops. Its 95%+ power transmission efficiency makes steering 60% lighter at low speeds (≤30km/h), reducing driver fatigue. Data shows it stays stable in 85% of urban traffic (congestion, intersections).
2. Long-Distance Highway Driving
Perfect for trips ≥200km. With 6500rpm max speed, it adapts to 80-120km/h steering needs. The energy-saving valve cuts 20% idle power loss, saving 0.4-0.6L/100km fuel—ideal for cost-saving long hauls.
3. Complex Road Condition Driving
Suitable for gravel, mountain, or muddy roads. Ceramic oil seal resists -40℃ to 120℃; ADC12 housing endures 15J impacts. Operates normally in 95% of harsh road tests.
4. Commercial Fleet Operations

Product Operate Guide
Install per the manual: Align interfaces (no impurities), fix bolts (10.9-grade), finish within 25 mins. Do not disassemble sealed parts.
Before startup: Check oil level (meets ISO VG 32/46), idle for 3 mins first to expel air.
Daily care: Inspect oil monthly; replace if turbid. Test pressure (0-14MPa) every 50,000 km.
Avoid overloading. Preheat/cool for extreme temps (<-40℃/>120℃) to extend 300,000 km lifespan.
