The ADU pump, a variable displacement axial piston pump, operates by adjusting the swashplate angle to control plunger stroke, enabling precise, stepless flow regulation proportional to drive speed. This design ensures optimal efficiency in dynamic load conditions. Key features include hydraulic or mechanical variable mechanisms and a closed-loop configuration, making these pumps ideal for high-precision applications in construction machinery, industrial equipment, and specialized drilling systems.


Our product lineup includes several proven models:


ADU062R05AA11 and its variants: Heavy-duty plunger pumps (80kg, 2600 RPM, 1200 head) designed for robust performance.

ADU041/049R08AB10A4314000A1AB100CD0A: A lightweight gear pump (4kg) operating at 3000–5000 RPM, suitable for compact systems.

ADU041/49/62RL series: Piston pumps with 41–62cc displacement, 1800 RPM rating, and support for electronic or hydraulic variable control.

PVH074R+ADU041R dual variable piston pump: Engineered specifically for drilling rigs, with customization options available.

ADU041/049/062RL vane pump series: With a flow rate of 18m³/h and weight of 55kg, ideal for industrial hydraulics.

Additional models such as the 421AK00933C ADU049L02AD10AC430000000200100CD0 (10kg, manual drive option) are compatible with a wide range of hydraulic machinery, offering flexibility and ease of integration.
