Kawasaki K3VL45 Series Variable Displacement Axial Piston Pumps

Product Overview: The Kawasaki K3VL45 Series is a premier variable displacement axial piston pump designed for both industrial machinery and mobile engineering vehicles. As the “heart” of the hydraulic system, the K3VL series delivers an exceptional power-to-weight ratio thanks to its advanced swashplate design and optimized flow geometry. This category focuses on precision models: K3VL45B-10 RMM-PO and K3VL45/B-1NRKS-L0. Equipped with precise Load-Sensing (LS) control, these pumps dynamically adjust output flow based on actuator demand, significantly improving fuel efficiency and reducing system heat generation. It is the industry choice for excavator main pumps, mobile cranes, injection molding machines, and Hydraulic Power Units (HPUs).

Key Technical Advantages:

• Superior Self-Priming: The unique intake flow path ensures excellent suction performance even at high speeds, minimizing the risk of cavitation.

• High-Pressure Reliability: Handles continuous operating pressures of 320 Bar with peak capabilities up to 350 Bar, ensuring robust power for heavy-duty cycles.

• Versatile Control Options: Supports Pressure Compensation (DR), Load Sensing (LS), and Torque Control to match complex hydraulic logic requirements.

• Compact Footprint: Optimized for space-constrained installations, making it easy to integrate into tight chassis environments like modern excavators.

• Technical Spec Decoding:

  • K3VL45: 45cc/rev frame displacement.

  • B-10 / B-1N: Indicates design series and internal component optimization.

  • RMM / RKS: Relates to rotation direction (R for Clockwise), mounting flanges, and shaft types.

  • PO / L0: Relates to specific pressure or flow regulator preset configurations.
