Rexroth A10VO71 Pump | A10VO71DRG/31L | 280 Bar Variable Piston Pump

Rexroth A10VO71 Series (Series 31) Variable Axial Piston Pump

Product Overview: The Rexroth A10VO71 is one of the most versatile variable displacement pumps for industrial and mobile Open Circuit hydraulic systems. As a core member of the proven Series 31 family, this 71cc unit delivers robust power under a continuous rated pressure of 280 Bar. This showcase highlights the DRG Control (Remote Pressure Compensation) version, which allows for precise system pressure adjustment via an external pilot line—ideal for multi-pump systems or applications requiring remote pressure regulation.

Key Technical Advantages:

• DRG Remote Pressure Control: Models like the A10VO71DRG/31L integrate a high-sensitivity compensator valve. By using a remote pilot oil path, operators can easily achieve stepless pressure modulation, significantly enhancing operational flexibility.

• Superior Power-to-Weight Ratio: The compact housing design, combined with heavy-duty internal rotating groups, enables massive flow output within a small footprint, perfect for modern compact Hydraulic Power Units (HPU).

• Exceptional Self-Priming Ability: Optimized inlet porting ensures the pump maintains excellent suction performance at rated speeds, drastically reducing the risk of cavitation and extending service life.

• Low Noise & Low Pulsation: Utilizing Rexroth’s patented valve plate noise-reduction technology, these pumps effectively suppress fluid pulsations, maintaining quiet and stable operation even at pressures exceeding 25 MPa.

• Robust Thru-Drive Capability (K07): Features superior thru-drive performance. Codes like K07 allow for tandem mounting of a secondary pump (such as another A10VO or a gear pump), streamlining complex multi-circuit layouts.
