Large Excavator
KC-AP2D 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-light machinery such as mini excavators (6-7 ton class), concrete pumps, and industrial equipment.
Advantages
Dual-Pump Design: Independent control of two hydraulic circuits for multi-function operation.
Compact Tandem Layout: Space-saving design with high power density for mobile applications.
Constant Power Control: Adaptive torque management under varying loads via integrated regulators.
Through-Shaft Integration: Enables mounting of a third pump or pilot pump (e.g., gear pump) 1.
Load Sensing Compatibility: Optional pressure-compensated control for energy-efficient load matching 18.
Self-Priming: Reliable start-up without external priming.
Modular Construction: Easy maintenance with interchangeable components 19.
Low Noise: Optimized valve plate and rigid casing reduce vibration and noise levels.
High Efficiency: Hydraulic balance and spherical valve plate ensure >90% peak efficiency 1.
Durable Build: Heavy-duty piston/slipper assembly with wear-compensating mechanisms.
Wide Control Options: Supports mechanical, hydraulic, or electrical input for versatile system integration.
