FAQ:

What are the key technical specifications?

• Displacement (Vg max): 71 cm³/rev

• Nominal Pressure (p nom): 280 bar

• Maximum Pressure (p max): 350 bar

• Speed Range: Up to 2,200 rpm (at Vg max)

• Flow Rate (at nominal speed): 156 L/min

• Weight: ~33 kg (standard model)

• Control Options: Pressure cutoff (DR type), load sensing, or proportional control variants.

3. How does the "pressure cutoff" function work?

The A10VSO71DR variant features a pressure cutoff (DR control) mechanism. When system pressure reaches the preset cutoff value, the pump reduces its displacement to maintain constant pressure, minimizing energy consumption. Contrary to some misconceptions, the swashplate does not always return to the minimum angle; it adjusts dynamically based on flow demand while sustaining pressure.

4. What are common applications?

This pump is ideal for:

• Hydraulic presses and injection molding machines.

• Construction machinery (e.g., excavators, cranes).

• Marine and offshore systems.

• Industrial hydraulic power units.

5. How to troubleshoot performance issues?

• Low Flow/Output: Check for clogged filters, worn seals, or incorrect control settings.

• Overheating: Verify fluid viscosity, cooling system, or excessive pressure settings.

• Noise/Vibration: Inspect for cavitation, air ingress, or misalignment.

6. Where can I find repair services?

Certified repair centers (e.g., Shenzhen Ou Hang Fluid Power) offer testing and refurbishment for A10VSO71 pumps, including seal replacements, swashplate repairs, and performance validation.

7. Are there compatible accessories or valves?

Yes, Rexroth provides matched components like:

• Proportional valves (e.g., 4WE series).
