The A4VG90EP3 axial piston hydraulic pump is a high-pressure, variable displacement pump engineered exclusively for hydraulic excavators. Designed for closed circuit systems, it provides outstanding efficiency, reliable performance, and extended service life under heavy-duty excavation tasks. With a maximum speed of 3000 rpm and superior high-pressure capability, the A4VG90EP3 ensures powerful hydraulic output to support digging, lifting, and earthmoving operations in challenging environments.
Hydraulic Excavators: The pump is specifically designed for excavator hydraulic systems, delivering high-pressure power to the boom, arm, bucket, and swing functions.
Optimized to handle continuous heavy-duty cycles, ensuring consistent performance in excavation, trenching, foundation digging, and construction site operations.
High Efficiency: Variable axial piston design reduces energy loss and optimizes hydraulic power output.
High Pressure Performance: Capable of reaching up to 35MPa, supporting demanding excavation requirements.
Durable Structure: Built from steel and aluminum alloy components to withstand harsh construction environments.
Low Noise Design: Ensures improved operator comfort on job sites.
Long Service Life: Integrated oil filtration system enhances reliability and reduces maintenance costs.
