FAQ:

1. 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 applications, such as construction machinery, metallurgy, and marine equipment.
2. 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 (e.g. pressure/low/power control) 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
3. 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.
4. 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
Success 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
5. What are common faults and their solutions?
Low/No Flow: Check for clogged suction pipe, leaks, or low tilt angle of the inclined plate
Pressure Fluctuations: Inspect to control piston wear or foreign objects entering the variable mechanism
Overheating: Verify oil cleanliness (NAS ≤ 9) and cooling system
Leakage: Replace damaged shaft seal or check drain pipe design
Noise: Ensure proper oil suction pressure and coupling alignment
6. Maintenance recommendations?
Oil Quality: Use ISO VG 46 anti-wear hydraulic oil and regularly test for contamination
Seals: Inspect shaft seals every 2000 hours to shorten the cycle in high temperature environments
Long Storage: Drain oil and add rust inhibitor
7. Where is the A10VSO71 typically applied?
• Industrial: Metallurgy, presses, plastic injection machines.
• Mobile: Concrete pump trucks, excavators, deck machinery.
Energy Sensitive Systems: Cranes, winches with power control requirements
