HydraulicAxial Piston Pump

Model: K3V140DT-9C, K3V140DT-9N, K3V140DT-HNOV

The K3V140DT is a 140mL/r variable displacement swashplate axial piston pump from the Kawasaki K3V series. It belongs to the same series as the K3V63DT/K3V112DT, sharing the same core features, control logic, and reliability design, but with a larger displacement. It is suitable for medium to large-sized construction machinery such as 25-30 ton excavators, with a rated pressure of 34.3MPa and a maximum of 39.2MPa. It offers stronger power and flow rate, meeting the demands of complex operations under greater loads.

Energy Efficiency: Variable displacement design allows for on-demand flow adjustment, reducing unnecessary energy consumption and heat generation, lowering fuel consumption of mobile equipment, and significantly reducing operating costs over the long term.

Wide Adaptability: Rated pressure 34.3MPa, maximum pressure 39.2MPa, suitable for medium and high pressure conditions of various construction machinery such as excavators, cranes, and loaders, with strong ability to handle load fluctuations.

Convenient Maintenance: As a mature series, spare parts are readily available, maintenance technology is widely available, and it has strong anti-pollution capabilities. Routine maintenance only requires periodic checks of oil cleanliness and filter condition, reducing maintenance difficulty and cost.

Precise Operation: Multiple control modes enable precise control of the speed and force of actuators, improving equipment operating accuracy and stability, especially suitable for complex construction machinery operations.

Primarily used in 25-30 ton class excavators (such as Hyundai R290LC-7, Komatsu PC220-8, etc.), crawler drilling rigs, cranes, crushers, concrete pumps and other mobile hydraulic equipment. It is compatible with open circuit systems and can meet the high-efficiency power output and precise control requirements of equipment during complex actions. It is one of the mainstream choices for hydraulic systems of medium and large-sized construction machinery.
