Rexroth A10VSO71DFR1 High Pressure Piston Pump 71 cm³/rev

• 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

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. The swashplate adjusts dynamically based on flow demand while sustaining pressure.

This pump is ideal for hydraulic presses, injection molding machines, construction machinery (e.g., excavators, cranes), marine and offshore systems, and industrial hydraulic power units.

• 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

Certified repair centers offer testing and refurbishment for A10VSO71 pumps, including seal replacements, swashplate repairs, and performance validation.

Rexroth provides matched components like proportional valves (e.g., 4WE series), pressure relief valves (DBW series), and servo drives for advanced control. For full technical documents or model-specific queries, consult Rexroth's official manuals or authorized distributors.
