Product Introduction
1011100-ED01A High-Grade Long-life Precision-machined Oil Pump for Great Wall Motor
The 1011100-ED01A oil pump is a core engine component engineered for reliable lubrication system performance. It delivers a stable oil flow of 8-12 L/min (tested under standard operating conditions) to circulate oil, reducing friction and cooling critical engine parts.
Manufactured in line with ISO 9001 quality standards, this pump features a precision-machined housing and high-wear-resistance internal components, ensuring a service life of up to 5,000+ working hours. It’s designed for easy installation, compatible with professional maintenance workflows, and undergoes 100% pressure leakage testing before delivery to guarantee operational safety.
Product Advantage
1. ISO 9001 Certified Quality with High-Grade Materials
This ISO 9001 certified oil pump is manufactured using high-grade aluminum alloy for the housing and carbon steel for internal gears—materials selected after 500+ hours of wear resistance testing. The precision-machined components reduce internal friction by 22% compared to standard oil pumps, ensuring stable operation even in high-temperature engine environments. Every batch undergoes material composition testing, with a qualification rate of 100%, to avoid premature failure caused by substandard materials.
2. Stable Oil Flow & Pressure for Optimal Lubrication
As a high-performance oil pump, it delivers a consistent oil flow rate of 8–12 L/min (tested at 3,000 RPM) and maintains a pressure stability of ±0.2 bar. This prevents oil starvation in critical engine parts, such as crankshafts and camshafts, reducing mechanical wear by up to 30%. The integrated pressure relief valve is calibrated with a tolerance of ±0.1 bar, automatically adjusting oil pressure to protect the engine from overpressure damage—ideal for heavy-duty operating conditions.
3. Extended Service Life with Anti-Corrosion Design
Designed for long-term reliability, the long-life engine oil pump boasts a service life of 5,000+ working hours, exceeding the industry average of 3,500 hours by 43%. The surface of the housing is treated with a ceramic coating, which passed a 48-hour salt spray test without signs of corrosion. Internal gears are heat-treated to a hardness of HRC 58–62, enhancing resistance to wear and deformation. This design minimizes replacement frequency and lowers maintenance costs for end-users.
4. Easy Installation & Wide Compatibility
The precision-machined oil pump for engine lubrication features a bolt-hole positioning accuracy of ±0.05 mm, ensuring alignment with engine mounting points. This reduces installation time by 25% compared to non-precision pumps, fitting seamlessly with standard professional maintenance tools. It is compatible with a range of engine lubrication systems, and we provide a detailed installation guide with torque specifications (25–28 N·m for mounting bolts) to simplify on-site operations for mechanics.
5. 100% Pre-Delivery Testing for Zero Defects
Before leaving the factory, each 1011100-ED01A oil pump undergoes two rounds of strict testing: a 30-minute pressure leakage test (with a maximum allowable leakage of 0.5 mL/min) and a 2-hour dynamic balance test (to eliminate vibration caused by component imbalance). The overall product qualification rate after testing is 99.8%, and we provide a test report for each unit—giving customers clear proof of performance and quality.

Product Uses
Here are specific application scenarios of oil pump:
1. Daily Commuter Vehicle Operations
For vehicles used in daily urban commuting—characterized by frequent starts, stops, and low-speed driving—the pump maintains a steady oil flow of 8–10 L/min. This prevents oil starvation in engines that alternate between idle and low-load states, reducing mechanical wear by 30% compared to generic pumps. Its anti-leakage design (tested to ≤0.5 mL/min leakage) also avoids oil waste, making it ideal for long-term daily use.
2. Heavy-Duty Load-Bearing Scenarios
In vehicles handling heavy loads (e.g., cargo transport, equipment hauling), the pump operates at a stable pressure of 3.5–4.0 bar. It sustains consistent lubrication even when engines run at 4,000–5,000 RPM for 8+ hours continuously, protecting critical parts like crankshafts from excessive friction. The heat-treated gears (HRC 58–62) resist deformation under high load, ensuring no performance drop during heavy-duty work.
3. Extreme Temperature Environments
The pump performs reliably in temperatures ranging from -40°C to +120°C. In cold regions, its quick oil circulation (≤3 seconds of cold-start 供油 response) avoids dry friction during engine warm-up. In high-temperature areas, the ceramic-coated housing reduces heat absorption by 15%, keeping internal components within a safe operating temperature range and preventing oil viscosity degradation.
4. Professional Maintenance & Aftermarket Replacement
As a go-to replacement part for professional repair shops, the pump’s precision-machined mounting holes (±0.05 mm tolerance) ensure 100% alignment with engine interfaces. This cuts installation time by 25% compared to non-standard pumps. Each unit comes with a test report, allowing mechanics to verify performance (e.g., flow rate, pressure) before installation, reducing post-repair troubleshooting.
5. Fleet & Commercial Vehicle Maintenance
For commercial fleets (e.g., delivery fleets, public transport), the pump’s 5,000+ working hour service life lowers replacement frequency by 43% versus industry averages. Its compatibility with multi-grade oils (5W-30 to 10W-40) eliminates the need for oil type adjustments across fleets, simplifying maintenance workflows. The 12-month warranty also provides fleet managers with long-term quality assurance.
Product Operate Guide
Pre-installation: Inspect the pump’s seal (NBR material) for cracks—this prevents leakage exceeding 0.5 mL/min. Clean mounting surfaces to remove debris.
Installation: Tighten bolts to 25–28 N·m (use a torque wrench); over-tightening may damage the aluminum alloy housing.
Post-installation: Idle the engine for 3 minutes, check oil pressure (should reach 2.5–4.0 bar).
Maintenance: Replace oil per vehicle specs; the pump works best with 5W-30/5W-40/10W-40 oils.
