Kawasaki K3VL Series Variable Piston Pump for Excavator Main Hydraulic Systems

Product Overview: The Kawasaki K3VL series is a range of high-performance swashplate axial piston pumps engineered for Excavators, construction machinery, and industrial Open Circuit systems. As a global leader in hydraulic reliability, the K3VL series spans a full displacement range from 45cc (K3VL45) up to 140cc (K3VL140). With superior self-priming capabilities and a continuous operating pressure of 320 Bar, these pumps effortlessly handle the complex compound movements and high-intensity duty cycles required in excavation. By integrating advanced Load Sensing and Pressure Compensation, the K3VL series ensures smoother operation and faster system response.

Key Technical Advantages:

• Optimized for Excavators: Built for high-frequency dynamic cycles. Models like the K3VL140/B-10RMM-P0 feature rapid displacement response, significantly boosting the excavator’s cycle time and productivity.

• Intelligent Control Modulations (P0/M):

  • Load Sensing (LS): Senses load pressure in real-time to modulate flow output, reducing overflow losses and slashing fuel consumption.

  • Pressure Compensator: Automatically de-strokes the pump when preset pressure is reached, protecting hydraulic components and minimizing system heat.

• Superior Power Density: The compact housing design combined with high-strength internal components offers an excellent power-to-weight ratio, ideal for tight engine compartments.

• Heavy-Duty High-Pressure Reliability: Rated at 320 Bar (4600 PSI) with peak capabilities up to 350 Bar, maintaining exceptional volumetric efficiency under extreme digging conditions.

• Low Noise Design: Utilizing Kawasaki’s patented valve plate noise-reduction technology, these pumps effectively suppress fluid pulsations, meeting modern environmental and low-noise standards for mobile machinery.
