Frequently Asked Questions
What is the A10VSO71 series?
The A10VSO71 is a variable displacement axial piston pump with a 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, such as construction machinery, metallurgy, and marine equipment.
What are the key features of the A10VSO71 pump?
- Pressure Range: Nominal pressure of 280 bar, peak pressure of 350 bar
- Flow Control: Flow is proportional to drive speed and displacement, adjustable via swashplate angle
- Efficiency: Energy saving modes reduce energy consumption by 30% compared to fixed pumps
- Durability: Fluorocarbon (FKM) shaft seals, fluid hydrostatic bearing technology, and low noise design
- Versatility: Supports through shaft drive for additional pump installation
What control options are available?
The series offers multiple control modes:
- DR/DRG: Pressure control (direct or remote)
- DFR: Pressure and Flow Composite Control
- DFLR: Integrated Control of Pressure, Flow, and Power
- ED/EP: Electrohydraulic proportional control
How to install the pump correctly?
- Orientation: Prefer horizontal shaft mounting; Vertical installation requires rough oil priming and air blending
- Drain Lines: The shell drain ports (L1/L2) must be separately led to the fuel tank, with a back pressure of ≤ 0.5 bar
- Suction Pressure: Maintain ≥ 0.8 bar absolute at the inlet (≥ 0.5 bar during cold start)
- Piping: Use SAE standard flange ports and vibration solubilizing connectors
