Kawasaki K3V112DT Series Tandem Axial Piston Pumps for Excavators

Product Overview: The Kawasaki K3V112DT is the global benchmark for hydraulic systems in construction machinery. As a high-pressure tandem axial piston variable displacement pump, it is specifically engineered for 20-25 ton hydraulic excavators. Featured models like the K3V112DT-1XJR-9M2X-V leverage advanced “Negative Flow Control” and “Constant Power Regulation” technologies to deliver precise flow at continuous pressures up to 34.3 MPa. Renowned for its superior volumetric efficiency, extended service life, and robust resistance to harsh job site conditions, the K3V112DT is the premier choice for main pumps in leading brands such as Kobelco, Hyundai, Doosan, and SANY.

Key Technical Advantages:

• Superior Power Density: The compact tandem architecture delivers high-flow dual output within a limited footprint, perfectly matching the power demands of complex excavator compound movements.

• High-Response Negative Control: Sensitively detects pilot signals to modulate displacement, achieving significant energy savings by reducing standby flow while enhancing operator control precision.

• Extreme Structural Durability: Features reinforced pump housings and specially treated internal rotating groups (pistons and valve plates) to ensure stability during high-intensity operations like mining and heavy-duty digging.

• Global Interchangeability: Strictly adheres to international mounting standards. Configurations like 1XJR-9M2X-V ensure 100% “drop-in” replacement for major excavator models, minimizing downtime costs.

• Quiet Operational Profile: Unique noise-suppression design effectively mitigates hydraulic pulsation at high pressures, reducing overall machine noise to meet modern environmental standards.
