KYB PSV2-52T & PSV2-60T Pump | PSV2-63T, PSV2-66T-1 | Hydraulic Main Pump for Excavator

KYB PSV2 Series Axial Piston Main Pump for Excavators

Product Overview: The KYB PSV2 series is the high-performance power heart for mid-sized excavator hydraulic systems worldwide. Engineered specifically for the 6-ton to 13-ton excavator class, this series is renowned for its superior power density and exceptional control precision. Featured models like the PSV2-52T, PSV2-60T, and PSV2-66T-1 utilize advanced load-sensing technology to ensure stable and efficient power output during heavy digging and complex simultaneous functions (e.g., traveling while lifting the boom).

Key Technical Advantages:

• Precision Load-Sensing Control: Automatically modulates output flow to match actuator demand, drastically reducing relief losses and hydraulic fluid temperature.

• High-Pressure Durability: Built with reinforced components to support rated pressures of 30-34.3 MPa, ensuring reliability under harsh rock-breaking and heavy excavation conditions.

• Dynamic Response Excellence: Optimized servo-variable mechanisms provide agile displacement switching, enhancing machine cycle speeds and operator feedback.

• Compact Integrated Architecture: Features built-in pilot pumps and regulator valve groups, minimizing installation footprint and reducing potential leak points.

• 100% OEM Standard Compatibility: Manufactured to strict KYB factory specifications, ensuring splined shafts and mounting flanges align perfectly for a seamless “drop-in” replacement on major excavator brands.
