Use For Hitachi Hydraulic Pump 9197075 4447599 ZX650H ZX600, ZX650H, ZX800, ZX850H Pump Assemblies Crawler Excavator Mining Excavator Construction Machinery Aftermarket Parts manufacturer

High-performance main piston pump designed for Hitachi ZX650H ZX600, ZX650H, ZX800, ZX850H excavators and compatible with various construction machinery applications.

 

The Hitachi ZX650H ZX600, ZX650H, ZX800, ZX850H excavators hydraulic pump, model 9197075 4447599, is part of the Komatsu series of swashplate-type variable displacement dual piston pumps.

• Displacement Range: 200 ml/rev (specific models may support a wider adjustment range)
• Pressure Rating: Rated 35 MPa, peak 40 MPa
• Control Mode: Supports LA0/LA1 dual-mode split power control, allowing independent adjustment of power for both piston assemblies
• Integrated Functions: Built-in auxiliary gear pump, relief valve, and PTO (Power Take-Off) expansion interface

• Designed for construction machinery, such as the Hitachi ZX650H ZX600, ZX650H, ZX800, ZX850H and other large excavators
• Meets precise power matching requirements under heavy-duty operating conditions
• Utilizes load-sensing control technology to dynamically adjust pump output flow
• Reduces energy consumption (approximately 25% more efficient than conventional pumps)
• Minimizes hydraulic system heat generation

• Installation Requirements: Requires a flexible coupling with high shaft alignment accuracy (concentricity deviation ≤ 0.1 mm, tilt angle < 1°)
• Maintenance Guidelines: Recommended use of ISO VG46 anti-wear hydraulic oil with a cleanliness level of NAS Class 7
• Regularly monitor oil temperature, pressure pulsation, and piston wear
