XCMG XE2000 Excavator Independent Cooling Pump (804001731): The Core of Heat Dissipation Under High-Temperature Conditions

In the power system of the XE2000 large mining excavator, heat dissipation efficiency directly determines whether the equipment can operate stably and continuously under high-temperature and heavy-load environments. XCMG’s independently developed cooling pump (part number: 804001731) for this model, with its powerful cooling performance and reliable operation, is a key piece of equipment ensuring the low-temperature operation of the machine’s core components.

Ultra-Large Flow Output, Powerful Temperature Control to Prevent Overheating

The mining operating environment is characterized by high temperatures and heavy equipment loads. Engines and hydraulic systems are prone to performance degradation due to heat accumulation. This independent cooling pump adopts a high-efficiency impeller design and a large-displacement pump body structure, with a rated flow rate of up to 180L/min, enabling rapid high-speed circulation of coolant in the heat dissipation circuit. Through precise coordination with the radiator, the engine coolant and hydraulic oil temperatures can be stably controlled within the optimal range (coolant temperature ≤ 95℃, hydraulic oil temperature ≤ 85℃), effectively avoiding power attenuation and accelerated component aging caused by overheating. This ensures that the XE2000 maintains strong power output even under high summer temperatures or prolonged full-load operation.

Wear-resistant structural design adapts to extreme working conditions

Mining equipment cooling systems constantly face severe challenges such as dust erosion and vibration impact. The 804001731 cooling pump features a high-strength cast iron pump casing, a wear-resistant alloy impeller, and double-row angular contact ball bearings in key bearing areas. After special heat treatment, its wear resistance is improved by over 40%. Its sealing structure uses a skeleton-type mechanical seal, effectively preventing coolant leakage and dust intrusion. Under the high-intensity operation of 16 hours per day and environmental dust concentration exceeding standards in mining conditions, its continuous trouble-free operation time exceeds 2000 hours, far exceeding the service life of similar products in the industry.

Original Factory Precise Fit, Ensuring Efficient Machine Operation

As a core original XCMG component, this independent cooling pump is deeply matched to the power parameters of the XE2000 excavator. Specifically tuned for the XE2000’s 810kW high-power engine and high-pressure hydraulic system, the pump’s speed and flow characteristics intelligently adjust heat dissipation intensity based on engine load and ambient temperature, avoiding unnecessary energy consumption. Furthermore, its installation dimensions and connection interfaces perfectly conform to original factory design standards, allowing for direct replacement without modification. This ensures a highly efficient and coordinated cooling system with components such as the water tank, thermostat, and radiator fan, guaranteeing optimal operation of the entire machine’s thermal management system.

The XCMG XE2000 excavator independent cooling pump (part number 804001731) – with its high-flow-rate, highly effective temperature control, wear-resistant structure, and original factory fit, it is an indispensable core component for heat dissipation in large mining excavators under high-temperature, heavy-load conditions.
