Large Excavator
The Kawasaki K3V140DT is a variable displacement axial piston pump (swash plate type) with a dual-pump (tandem) configuration, designed for high-pressure hydraulic systems in medium-to-heavy machinery such as excavators (14-16 ton class), concrete pumps, and industrial equipment
Applications
Dual Flow Control (DT): Independent management of two hydraulic circuits for precise system adaptation .
Compact Tandem Design: Space-saving layout with high power density (output/mass ratio) .
Low Noise: Optimized valve plate and rigid casing reduce vibration and noise levels .
High Efficiency: Spherical valve plate and hydraulic balance ensure >90% peak efficiency, even at low speeds/pressures .
Durable Build: Heavy-duty piston/slipper assembly with wear-compensating mechanisms for extended service life .
Wide Control Options: Supports load sensing, constant power control, and electro-hydraulic proportional control (via optional regulators).
Self-Priming: Reliable start-up without external priming .
Through-Shaft Design: Enables integration of a third pump or pilot pump .
Modular Design: Easy maintenance with interchangeable components .
High Power Density: Lightweight yet robust for demanding applications .
