Frequently Asked Questions
What is the A10VSO71 series?
The A10VSO71 is a variable displacement axial piston pump with
swashplate design, designed for hydrostatic transmission in open
circuits. It offers stepless flow regulation by adjusting the
swashplate angle and is widely used in high-power hydraulic systems
for industrial and mobile appliions.
What are the key features of the A10VSO71 pump?
- Pressure Range: Nominal pressure of 280 bar, peak pressure of 350 bar
- Flow Control: Proportional to drive speed and displacement, adjustable via
swashplate angle
- Efficiency: Energy saving modes reduce consumption by 30% compared to fixed
pumps
- Durability: Fluorocarbon (FKM) shaft seals and fluid hydrostatic bearing
technology
What control options are available?
The series offers multiple control modes including pressure control
(DR/DRG), pressure and flow composite control (DFR), integrated
control of pressure, flow and power (DFLR), and electrohydraulic
proportional control (ED/EP).
How to install the pump correctly?
- Prefer horizontal shaft mounting
- Shell drain ports must be separately led to the fuel tank
- Maintain ≥ 0.8 bar absolute pressure at the inlet
- Use SAE standard flange ports and vibration-resistant connectors
