KYB PSVL-54CG & PSVL2-36CG Pump | PSVL-54CG-16, PSVL-54CG-14 | Hydraulic Main Pump for Excavator

KYB PSVL & PSVL2 Series Axial Piston Main Pump for Excavators

Product Overview: The KYB PSVL and PSVL2 series represent the high-performance power standard for midi-excavator hydraulic systems worldwide. Specifically engineered for the 5-ton to 9-ton excavator class (compatible with brands like Kubota, Sany, and Yanmar), these axial piston variable displacement pumps are renowned for their superior Load Sensing (LS) control and exceptional volumetric efficiency. Featured models like the PSVL-54CG-16, PSVL-54CG-14, and the upgraded PSVL2-36CG-2 modulate flow instantaneously based on operational demand, ensuring balanced power distribution and responsive control during heavy digging and complex simultaneous functions.

Key Technical Advantages:

• Precision Load-Sensing (LS) 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 cast iron and precision-lapped rotating groups to maintain unmatched reliability under rated pressures of 24.5-28 MPa.

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

• Compact Integrated Architecture: Features built-in regulator valve groups, simplifying hydraulic plumbing and reducing potential leakage points on the machine.

• 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.
