Product Description
KYB PSVK2 Series Axial Piston Main Pump for Excavators
Product Overview: The KYB PSVK2 series is the high-performance power heart for mid-sized excavator hydraulic systems worldwide. Specifically engineered for the 5-ton to 9-ton excavator class, this axial piston variable displacement pump series is renowned for its superior power density and precise Load Sensing (LS) control. Featured models like the PSVK2-25CKG-HS-6 and PSVK2-27CKG-HS-7 utilize advanced regulator technology to ensure balanced power distribution and responsive, fuel-efficient control during heavy digging and simultaneous operations.
Key Technical Advantages:
Precision Load-Sensing Control: Automatically modulates output flow to match real-time actuator demand, drastically reducing energy waste and minimizing hydraulic fluid heat generation.
Reinforced Heavy-Duty Construction: Built with high-strength materials and precision-lapped rotating groups to maintain peak volumetric efficiency under rated pressures of 28-32 MPa.
Rapid Dynamic Response: Optimized servo-variable mechanisms provide agile displacement switching, enhancing machine cycle speeds and operator feedback sensitivity.
Quiet Operation & Longevity: Optimized internal fluid passages suppress hydraulic pulsation and noise, extending the service life of bearings and seals in harsh environments.
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 Sany, Kubota, and Kobelco machines.
