1. Precise gear engagement ensures efficient energy conversion

The core performance of gear pumps relies on the precise meshing of gears and low-loss power transmission—Liugong 11C2467 The gear pump achieves a dual breakthrough in gear design and manufacturing: adopting “ Involute Profile Shifted Gear ”  Optimize the design through computer-aided engineering ( CAE ) Simulate the gear meshing process and keep the tooth side clearance within 0.02–0.05 mm Between them, hydraulic oil leakage is significantly reduced, and volumetric efficiency is improved to 95% Above, it saves more energy compared to ordinary gear pumps. 8%-12% , effectively reducing engine fuel consumption; the gear tooth surfaces utilize “ Carburizing and Quenching +  Fine grinding ”  Craftsmanship, with surface hardness reaching HRC60-62 , tooth surface roughness controlled within Ra 0.4 μm The following not only reduces meshing wear but also lowers transmission noise (idle running noise). ≤68dB ), extending the service life of the gears. Tests have shown that, under continuous 1000  Under hourly heavy-load operating conditions, the volumetric efficiency decay rate of this gear pump is less than 3% , significantly lower than the industry average 5% The attenuation standard ensures the long-term, efficient operation of the hydraulic system.

II. High-strength structural design to withstand impacts under complex operating conditions

When operating construction machinery, gear pumps must withstand multiple challenges, including high pressure, vibration, and fluctuating oil temperatures—making structural strength the key to their reliable performance. LiuGong 11C2467 The gear pump housing is made from high-strength aluminum alloy. ADC12+T6 Heat-treated material, with tensile strength reaching 320MPa , yield strength exceeds 220MPa , lighter than conventional cast iron housings 30% At the same time, impact resistance is enhanced. 40% ; Key stress-bearing parts inside the housing (such as gear bearing seats and oil suction/discharge ports) have their wall thickness optimized using finite element analysis, with local thickening applied to 12-15mm , strengthen the structural support capability to prevent shell deformation under high-pressure conditions, which could otherwise lead to a decline in gear meshing accuracy; furthermore, the pump shaft is selected 40Cr After tempering and high-frequency quenching, the alloy steel achieves a surface hardness of HRC55-58 , with flexural strength reaching 800MPa , it can easily handle instantaneous impact loads, preventing pump shaft breakage or wear, and ensuring the long-term stable operation of the gear pump.

3. Efficient sealing and anti-contamination features extend maintenance cycles.

The sealing performance and anti-pollution capability of gear pumps directly affect their service life and the cleanliness of the hydraulic system. LiuGong 11C2467 The gear pump employs a sealing design that features “ Double sealing +  Anti-pollution structure ” : The shaft end seals are equipped with imported fluororubber skeleton oil seals, offering a temperature resistance range for oils. - 20℃ To 150℃ , effectively preventing hydraulic oil leakage while also blocking external dust from entering; the housing joint surface is sealed with anaerobic adhesive, ensuring that the flatness error of the sealing surface is kept within 0.03 mm/m Within this, thoroughly eliminate the risk of leakage; furthermore, the gear pump features a built-in oil suction port. 100μm Precision filter mesh that pre-filters large particulate impurities from hydraulic oil, reducing wear on gears and bearings while protecting downstream components of the hydraulic system. Designed specifically for harsh operating environments, this gear pump also features an optimized oil inlet channel design, minimizing suction resistance. As a result, it maintains stable oil intake even under conditions where hydraulic oil viscosity fluctuates significantly, effectively preventing potential issues. “ Cavitation ”  Performance degradation caused by the phenomenon extends the maintenance cycle compared to conventional gear pumps. 50% That's all.

4. Compatible with all机型, meeting diverse operational needs

Leveraging LiuGong's decades of experience in researching and developing hydraulic systems for construction machinery, 11C2467 The gear pump features a modular design, allowing for precise compatibility with the entire series of LiuGong medium-sized loaders. 5-8 Ton-class), excavator ( 13-20 Hydraulic systems rated in tons, while also being compatible with similar equipment from China's leading OEMs. Depending on the specific operational requirements, this gear pump is available in a variety of displacement specifications. 16-32mL/r ) With pressure rating (rated pressure 21MPa , Maximum pressure 25MPa ), which can flexibly match the power requirements of the equipment's hydraulic actuators. —— For example, when operating a loader lift, selecting a high-displacement model can increase the lifting speed; and in excavator swing operations, using a high-pressure model can enhance the swing torque. Additionally, the mounting interface of the gear pump adheres to ISO International standards ensure that flange dimensions and oil port thread accuracy meet the required specifications. 6H Level, it can be installed directly without modifying the hydraulic system pipelines, significantly enhancing adaptability and offering a convenient choice for both equipment manufacturers and end-users.

V. Rigorous Testing and Validation to Ensure Reliable Performance

Liugong vs. 11C2467 Gear pumps undergo comprehensive quality control and extreme testing across the entire process: During the raw material stage, key components such as the housing, gears, and pump shaft are subjected to material composition analysis, mechanical property testing, and non-destructive inspection to ensure the quality of the base materials. In the production process, each step is equipped with high-precision testing equipment (such as gear measuring centers and coordinate measuring machines) to continuously monitor critical parameters like gear meshing accuracy and shaft coaxiality. Finally, at the finished-product stage, the gear pump must pass 100  Hourly full-load cycling tests (simulating continuous heavy-duty operation of the equipment), 500  Next is the surge stress test (simulating sudden overload scenarios), followed by the high-and-low temperature cycling test. -40℃ To 100℃ ) and more than ten other rigorous tests to ensure stable operation even under extreme conditions. Meanwhile, LiuGong has established a comprehensive quality traceability system—each gear pump comes with a unique identification code, enabling full traceability of its production batch, inspection data, and after-sales records, thereby providing users with all-around quality assurance.

Liugong 11C2467 Gear pumps, with their precise gear meshing, high-strength construction, efficient sealing capabilities that resist contamination, and full model compatibility, have become essential components of hydraulic systems in construction machinery. “ High-efficiency Power Source ” Choosing it means not only selecting a high-quality hydraulic component, but also opting for stable, efficient, and reliable operational support—enabling your equipment to maintain robust hydraulic power in diverse and challenging environments such as mining operations, infrastructure construction, and road building, thereby boosting productivity and enhancing project profitability.
