XCMG XE2000 Excavator Flange Assembly (803418697): The Core Sealing Connection for High-Pressure Piping in Mining

In core mining regions worldwide, such as Indonesia, the Democratic Republic of Congo, and Brazil, the XCMG XE2000 mining excavator, with its massive 12-cubic-meter bucket capacity and over 93% mobility, has become a core piece of equipment for efficient mining operations. In the high-pressure piping system of this “mining giant,” the flange assembly (part number 803418697) acts as a “precision sealing joint,” undertaking the rigid connection between the main pump and main valve, and between the cylinder and the pipeline. It is a key component ensuring leak-free hydraulic oil transmission, providing a solid foundation for the machine’s efficient power output.

Original factory precision fit, seamless integration with hydraulic systems

The XCMG XE2000 excavator flange assembly (803418697) was specifically designed by the XCMG R&D team for the pressure parameters and piping layout of the XE2000 hydraulic system, undergoing 3D modeling analysis and high-pressure sealing testing. Its flange diameter accuracy is controlled within ±0.02mm, bolt hole tolerance ≤0.1mm, and sealing surface flatness error ≤0.05mm/m, perfectly matching key interface parameters such as the main pump outlet, main valve inlet, and cylinder ports. Whether in static high-pressure pipeline fixed connections or in dynamic operating vibration environments, it achieves a tight, precise connection, completely eliminating installation gaps or sealing failures caused by dimensional deviations, building a “zero-leakage” connection barrier for the hydraulic system.

High-strength Material and Manufacturing Process, Ensuring Durability Under Extreme Conditions

Made entirely of high-strength alloy structural steel (42CrMo), forged as a single piece, with a tensile strength of up to 1050MPa and a yield strength ≥900MPa after tempering heat treatment, possessing excellent resistance to compressive deformation and fatigue. The sealing surface is precision ground to a surface roughness Ra≤0.8μm, ensuring a perfect fit with the sealing element. The surface undergoes phosphating treatment and multi-layer anti-corrosion chrome plating protection, with uniform coating thickness and strong adhesion. It withstands over 500 hours of salt spray testing. In high-humidity, dusty, and oily mining environments, its rust resistance is more than 40% higher than ordinary flange assemblies, and its service life is extended by more than 3 times.

Superior Sealing Design, Ensuring Safe Transmission of High-Pressure Media

The flange assembly is equipped with imported high-pressure resistant fluororubber gaskets, with a hardness controlled at 75±3 Shore A and a compression rebound rate ≥70%, capable of withstanding continuous working pressure of 400MPa. Featuring a tongue-and-groove sealing structure and precise bolt preload parameters (850-900 N·m), the XE2000 excavator effectively distributes pipeline pressure, preventing seal failure due to excessive local stress. When the XE2000 excavator is operating at full load, it ensures hydraulic oil passes through the connection point with a transmission efficiency of over 99.6%, providing continuous power support for the powerful digging operation of the 12 cubic meter bucket, eliminating power loss, environmental pollution, and component wear caused by leakage.

For mining companies seeking efficient operations, the XCMG XE2000 flange assembly (803418697) is not only a high-quality connection component but also the “sealing core” ensuring the safe operation of the high-pressure pipeline system. Choosing original equipment manufacturer (OEM) parts means choosing reliability that perfectly matches the performance of the XE2000 excavator’s hydraulic system, providing a solid pipeline connection guarantee for efficient mining operations.
