Product Details
The A10VSO71DFLR1/31R-PKC92N00 is a high-performance variable axial piston pump designed for demanding mining appliions. Manufactured by Rexroth, this German-engineered pump delivers reliable hydraulic power with precision control.
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.
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 reduce energy consumption by 30% compared to fixed pumps
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
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
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
