Kawasaki K3VL Series Pump | K3VL80, K3VL112, K3VL140 | 350 Bar Variable Piston Pump

Kawasaki K3VL Series Heavy-Duty Variable Axial Piston Pump

Product Overview: The Kawasaki K3VL series is a high-performance variable displacement pump range engineered specifically for medium-to-high pressure Open Circuit hydraulic systems. This series covers essential industrial displacements including 80cc (K3VL80), 112cc (K3VL112), and 140cc (K3VL140). Leveraging robust technology from construction machinery pumps, the K3VL series delivers exceptional reliability under a rated pressure of 320 Bar. By integrating advanced control modulations (such as L0/L1 Load Sensing), these pumps ensure that flow output precisely matches load demand, making them the premier power source for industrial power units, marine equipment, and mobile machinery.

Key Technical Advantages:

• Superior High-Pressure Reliability: Rated for a continuous operating pressure of 320 Bar (4640 PSI) with peak capabilities reaching 350 Bar, featuring reinforced rotating groups for longevity under grueling duty cycles.

• Exceptional Self-Priming Ability: Optimized inlet porting provides excellent suction performance, drastically reducing the risk of cavitation—ideal for applications with challenging reservoir placements.

• Versatile Precision Controls (NRSM/NRMM):

  • Load Sensing (L0/L1): Real-time sensing of system load pressure automatically adjusts displacement, slashing energy waste and suppressing heat generation.

  • Pressure Compensation & Power Limiting: Multiple regulator options (e.g., NRSM split control) ensure optimal power distribution throughout various machining cycles.

• Rapid Response & Low Pulsation: High-precision valve plates effectively suppress fluid pulsations, maintaining quiet and stable power delivery even at high pressure.

• Robust Thru-Drive Capability: Features superior thru-drive performance, allowing for tandem mounting of secondary pumps to streamline complex multi-circuit power distribution.
