Kawasaki K5V Series Main Hydraulic Pump for Excavators

Product Overview: The Kawasaki K5V series is the advanced evolution of hydraulic power for modern excavators. Developed as the successor to the legendary K3V series, the K5V offers increased power density and enhanced fatigue life within a compact envelope. This series covers key displacements from 80cc (K5V80) to 160cc (K5V160). Featured models, such as the K5V140DT (Tandem Pump) and K5V160DTP1F9R-9Y04-HV (with high-performance regulators), deliver continuous pressures of 34.3 MPa. It is the ideal power solution for 15 to 35-ton class excavators, ensuring exceptional performance during heavy-duty digging and rapid multi-function movements.

Key Technical Advantages:

• Higher Power Density: The K5V design allows for operation at higher pressures. Its reinforced rotating groups and bearing systems significantly increase power output per unit weight.

• Versatile Pumping Structures:

  • DT/DTP Configurations: Tandem dual-pump setups enable synchronized power allocation between travel motors and front-end attachments through precise modulation.

  • S / DP Configurations: Single pump or through-drive options offer flexible power expansion for various hydraulic circuits.

• Precision Regulator Technology (-9Y04-HV): Equipped with advanced hydraulic or electric proportional regulators, supporting Negative Flow Control (NFC) and Total Power Control to maximize fuel efficiency and minimize system shocks.

• Superior Durability & Vibration Resistance: The reinforced housing effectively resists hydraulic pulsations and external vibrations, extending the pump’s service life in harsh mining and construction environments.

• Low-Noise Engineering: Optimized valve plate designs effectively suppress fluid noise, making excavator operation compliant with increasingly stringent environmental regulations.
