A11VO and A11VLO series of both models lies a precision-engineered tilting swashplate mechanism.   By adjusting the swashplate angle, these pumps enable infinitely variable displacement—delivering higher output with greater angles and reducing flow as the angle decreases.   This design ensures optimal control and efficiency across diverse applications.


The A11VO series features proportional electronic control (24V, 200–600mA), allowing precise displacement adjustment via external signals.   It is ideal for industrial machinery requiring accurate flow regulation, such as machine tools and injection molding equipment.   In contrast, the A11VLO series utilizes mechanical or hydraulic variable control, offering rapid response and robust performance under heavy loads—making it particularly suited for demanding agricultural and forestry machinery, including harvesters and log skidders.


Key internal components, including the plunger cylinder block, drive shaft, and precision bearings, are designed to ensure reliable energy conversion and smooth operation.   The A11VO adjusts its swashplate electronically through a proportional solenoid, while the A11VLO relies on hydraulic pressure or mechanical feedback, enhancing durability in harsh environments.


In terms of performance, the A11VO operates at pressures up to 350 bar with a displacement range of 10–140 mL/rev, supporting electric proportional and load-sensing controls.   The A11VLO, optimized for rugged use, functions within 210–250 bar and offers 18–100 mL/rev displacement, utilizing mechanical or hydraulic variable mechanisms.
