XCMG XE2000 Excavator Main Pump (804001727): The Core Power Source of the Machine

In the hydraulic system of the XE2000 large mining excavator, the main pump is the core component that converts engine power into hydraulic energy. Its performance directly determines the equipment’s operating efficiency and reliability. The XCMG original main pump (part number: 804001727) is specially customized and developed for this model, becoming the core power guarantee for heavy-duty mining operations with its powerful power output, high energy efficiency, and excellent durability. Large Displacement Output, Powerful Performance for Heavy-Duty Operations

As a heavy-duty mining excavator, the XE2000 needs to cope with harsh working conditions such as high-intensity digging and heavy-duty material handling, placing extremely high demands on the main pump’s displacement and pressure output. This main pump adopts a dual-pump confluence design, with a rated displacement of 450mL/r and a working pressure of up to 35MPa, providing continuous and powerful hydraulic power to the boom, stick, bucket, and other working devices. In heavy-duty scenarios such as hard rock excavation and full-bucket hoisting, it can achieve rapid response output, reducing single-cycle operation time by more than 8% compared to ordinary main pumps, significantly increasing the workload per unit time and easily meeting the high-intensity production demands of large mines.

Intelligent variable control, high efficiency and energy saving, reducing fuel consumption

Faced with the high energy consumption and cost pressures of mining operations, the energy-saving performance of the main pump is particularly crucial. The 804001727 main pump is equipped with XCMG’s independently developed intelligent variable control system, which can adjust the displacement output in real time according to the working conditions: automatically reducing displacement to reduce energy loss during light-load operations, and instantly increasing displacement to ensure power supply during heavy-load operations. Through precise coordination with the engine ECU, it achieves optimal matching between the hydraulic system and the power system, reducing the overall fuel consumption rate by 6%-10%. Calculated based on an average of 16 hours of operation per day, it can save hundreds of thousands of yuan in fuel costs annually, creating significant economic benefits for mine operations.

Reinforced Structural Design for Durable Performance Under Extreme Conditions

The dust, vibration, and continuous high pressure of the mining environment pose severe challenges to the structural strength and wear resistance of the main pump. The main pump cylinder is made of high-strength ductile iron, achieving a hardness of HB250 or higher after age hardening treatment. The plunger and slipper are made of high-wear-resistant alloy material, combined with precision mirror finishing, reducing the coefficient of friction by 30%. Key seals are made of imported high-pressure resistant fluororubber, suitable for a wide temperature range of -30℃ to 120℃. Verified through 5000 hours of bench durability testing, its trouble-free operating cycle far exceeds the industry average. Under the high-intensity daily operation conditions of mining, its service life can reach over 8000 hours, significantly reducing downtime for maintenance.

Precise Original Equipment Matching for Seamless Overall Performance

As a core component of the XE2000, the main pump’s parameters are deeply integrated with the overall system. For the 810kW high-power engine in the XE2000, the main pump’s input speed and torque capacity have been precisely calibrated to ensure efficient and lossless power transmission. Simultaneously, it forms an optimized hydraulic circuit with system components such as the hydraulic tank, main valve, and return oil filter, reducing pipeline pressure loss and improving system response speed. Installation dimensions and connection interfaces strictly adhere to original factory standards, allowing for direct assembly without modification. This avoids power waste and system overheating issues caused by incompatible parameters from non-original parts, ensuring the machine performs at its best.

The XCMG XE2000 excavator main pump (part number 804001727) – driving efficient operation with powerful displacement, achieving energy saving and consumption reduction with intelligent control, and withstanding extreme working conditions with a reinforced structure, is a reliable power core for large mining excavators.
