Product Description

KYB PSVL Series Hydraulic Main Pump for Kubota KX121-3 Excavator

Product Overview: The KYB PSVL series stands as the quintessential power source for the hydraulic systems of Kubota KX121-3 and other KX-series compact excavators. Featured models PSVL-42CG-8 and PSVL-54CG-13 are specifically engineered to meet the high-load demands of 3.5 to 5-ton machinery. Utilizing advanced load-sensing technology, these pumps modulate flow instantaneously based on operational demand, ensuring precise power distribution and smooth multi-function movements while significantly reducing fuel consumption.

Key Technical Advantages:

  • Precision Load-Sensing Control: Automatically adjusts pump output to match system demand, minimizing relief losses and effectively lowering hydraulic fluid temperatures.

  • High-Response Variable Mechanism: Optimized for KX121-3 duty cycles, providing rapid displacement switching for more sensitive and efficient digging operations.

  • Reinforced Heavy-Duty Construction: Built with high-strength materials and precision-lapped components to maintain exceptional volumetric efficiency under rated pressures of 23-25 MPa.

  • Quiet Operation & Durability: Optimized internal fluid passages suppress hydraulic pulsation and noise, extending the service life of bearings and seals.

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

Detailed Models & Parameters:

  • Core Series: KYB PSVL Series.

  • Compatible Models: Kubota KX121-3, KX101, U35, U45.

  • Representative Models: PSVL-42CG, PSVL-42CG-8, PSVL-54CG-13, PSVL-54CG.

  • Displacements: 42 cm³/rev / 54 cm³/rev.

  • Pressure Ratings: Rated at 24.5 MPa (3500 PSI) continuous; Peak capability up to 28 MPa.

  • Rotation: R (Clockwise/CW).
