Product Description

Rexroth A8VO225 Main Hydraulic Pump for Doosan DX520LC-9C

Product Overview: The A8VO225 Series high-pressure swashplate axial piston pump is the hydraulic heart of the Doosan DX520LC-9C heavy crawler excavator. This featured model, A8VO225LA1KH10/72XRN1XXA25F0000C-S, is a tandem variable displacement pump designed for open-circuit systems, delivering massive hydraulic power from a single drive shaft. Utilizing Rexroth’s advanced LA (Individual Power Control) regulator, this pump perfectly matches the engine’s power curve, ensuring high-speed response and maximum fuel efficiency during heavy-duty digging and lifting operations.

Key Technical Advantages:

  • Heavy-Duty Excavation Performance: Specifically engineered for 50-ton class and larger excavators, built to withstand grueling construction environments and high-frequency pressure spikes.

  • Intelligent LA Power Control: Features the LA1 Constant Power Regulator, which automatically adjusts flow based on system pressure to prevent engine stalling while maximizing hydraulic output.

  • Compact Tandem Architecture: Integrates two independent variable mechanisms within a single housing sharing a suction port, drastically saving space in the excavator’s pump compartment.

  • Extended Industrial Longevity: Critical rotating components (cylinder block, pistons, valve plate) undergo high-grade heat treatment and surface hardening for ultra-long service life under 24/7 high-intensity cycles.

  • Precision OEM Alignment: Fully compliant with original mounting parameters for the Doosan DX520LC-9C, supporting “Plug-and-Play” replacement to minimize equipment downtime.

Detailed Models & Parameters:

  • Core Series: Rexroth A8VO Series 72 (High Pressure).

  • Applicable Machine: Doosan DX520LC-9C, DX500LC.

  • Full Model Code: A8VO225LA1KH10/72XRN1XXA25F0000C-S.

  • Displacement: 225 cm³/rev x 2 (Double output).

  • Control Type: LA (Individual/Constant Power Control).

  • Pressure Ratings: Rated at 350 Bar (5075 PSI) continuous; Peak capability up to 400 Bar.

  • Target Applications: Heavy mining excavators, heavy-duty stackers, and large crawler cranes.
