804034429 Gear Pump for XCMG XMR603VT Light Roller

Short Description:

804034429 gear pump is an original high-precision hydraulic power component for XCMG XMR603VT light combination roller. As a core pressure-generating and oil-supply unit of the auxiliary hydraulic system, it relies on precise gear meshing to complete hydraulic oil suction, pressurization and constant-pressure delivery. It provides stable and continuous hydraulic power for the machine’s auxiliary functional systems, ensuring steady oil supply for steering assist, hydraulic cooling and auxiliary control loops. With reliable constant-flow output and strong pressure stability, it guarantees coordinated and efficient operation of the whole machine’s hydraulic system under various construction working conditions.

description

Factory calibrated for XMR603VT auxiliary hydraulic flow and pressure parameters, the 804034429 gear pump adopts high-precision spur gear meshing structure and integral die-cast pump body. It features small volumetric loss, low internal leakage, stable constant flow and low noise operation. The optimized tooth profile and gap matching design effectively reduce friction loss and pressure fluctuation, adapting to long-term continuous operation and frequent load changes of roller auxiliary hydraulic systems. Ordinary non-standard gear pumps are prone to insufficient oil supply, pressure attenuation, loud operating noise and severe wear after long-term use, easily causing weak steering assist, poor hydraulic heat dissipation and unstable system action. The genuine 804034429 gear pump achieves accurate flow output and reliable pressure maintenance, effectively improving the overall stability and response sensitivity of the equipment’s auxiliary hydraulic system.

advantages

• Precision gear tooth profile machining ensures uniform flow output, effectively avoiding system pressure fluctuation and unstable auxiliary actions.

• Ultra-low internal leakage design maintains stable working pressure for a long time, preventing insufficient steering assist and hydraulic power attenuation.

• Integral high-rigidity pump body structure resists deformation under vibration, ensuring consistent gear meshing clearance and stable operation.

• Optimized friction pair and oil passage structure reduces operating noise and heat generation, improving continuous operation stability.

• Excellent wear and fatigue resistance adapts to long-term high-frequency operation, reducing failure rate and maintenance cost.

• Original factory parameter calibration perfectly matches XMR603VT auxiliary hydraulic logic, with high assembly accuracy and excellent interchangeability.

maintenance & replacement tips

• Regularly check the gear pump body, end covers and oil ports for oil leakage to ensure stable system pressure building.

• Monitor operating noise and pressure output; troubleshoot abnormal noise, jitter and insufficient oil supply in time.

• Replace hydraulic oil and filter elements regularly to prevent impurities from wearing gear pairs and floating plates.

• Check the mounting fastening state regularly to avoid looseness and offset caused by long-term construction vibration.

• Avoid long-term overload operation and idle dry running to prevent rapid wear of internal precision components.

• Replace with genuine 804034429 gear pump during overhaul to restore original hydraulic supply stability.
