Product Description

Komatsu PC200-8 & PC220-8 Excavator Main Hydraulic Pump Assembly

Product Overview: This high-performance hydraulic main pump assembly is specifically engineered for Komatsu PC200-8, PC210-8, PC220-8, and PC200LC-8 series excavators. As the “power heart” of the excavator’s hydraulic circuit, this double-pump assembly—featuring part numbers 708-2L-31430 and 708-2L-00500—delivers a stable, high-pressure oil flow to ensure smooth multi-function operation and powerful breakout force for the boom, arm, and swing mechanisms.

Key Technical Advantages:

  • Precision Flow Distribution & Control: Equipped with the advanced Closed-center Load Sensing System (CLSS). Models like the 708-2L-31411 accurately modulate displacement based on lever input, preventing engine stalls and significantly reducing fuel consumption.

  • Superior Durability for Heavy-Duty Cycles: Optimized for high-intensity mining and earthmoving tasks. The internal piston groups and port plates undergo specialized heat treatment for extreme wear resistance, extending the Mean Time Between Overhauls (MTBO).

  • 100% OEM Compatibility: Manufactured strictly to Komatsu OEM standards. Every mounting hole, drive shaft spline, and port configuration is a seamless match for 708-2L-00700, ensuring a “plug-and-play” installation to minimize machine downtime.

  • Rapid Dynamic Response: Optimized servo control valves ensure millisecond-fast response times during sudden load changes, providing the operator with delicate and precise machine control.

Specific Models & Technical Parameters:

  • Machine Compatibility: Komatsu PC200-8, PC210-8, PC220-8, PC240-8, PC200LC-8.

  • Core Part Numbers (P/N): 708-2L-31430, 708-2L-00500, 708-2L-00700, 708-2L-31411.

  • Component Type: Axial Piston Variable Displacement Double Pump.

  • Key Specifications: Rated operating pressure 34.3 MPa (350 Bar); Peak pressure 38 MPa; Compatible with standard Komatsu hydraulic fluid specifications.
