Rexroth A10V Series Pump | A10V28, A10V45, A10V63, A10V71 | 280 Bar DR Pressure Control

Rexroth A10V Series (A10V28-A10V71) Variable Axial Piston Pump

Product Overview: The Rexroth A10V series is the most widely utilized benchmark for variable displacement piston pumps in the industrial hydraulic sector. This series covers essential displacements including 28cc, 45cc, 63cc (A10V63), and 71cc (A10V71). Engineered for Open Circuit systems, the A10V series is most notably equipped with the highly reliable DR Pressure Regulator. Once the system reaches the preset pressure, the pump automatically reduces displacement to the minimum required to maintain pressure, drastically slashing energy consumption. With its compact swashplate design and superior power-to-weight ratio, the A10V series is the premier choice for injection molding machines, metal forming equipment, and automated production lines.

Key Technical Advantages:

• Precise DR Pressure Control: Models like the A10V63DR feature sensitive constant-pressure regulation, ensuring the system consumes minimal power during pressure-holding phases while effectively controlling oil temperature.

• Heavy-Duty Industrial Reliability: Rated for an operating pressure of 280 Bar (28 MPa) with peak capabilities reaching 350 Bar. Reinforced rotating groups and bearing designs ensure an extended service life under continuous high-pressure cycles.

• Flexible Configuration Options:

  • DR1/DR3 Controls: Provides various sensitivity levels for pressure compensation.

  • P18/P1B Shaft Ends: Supports multiple keyed or splined shaft specifications for seamless coupling with diverse electric motors and gearboxes.

• Low Noise Operation: Utilizes Rexroth’s patented valve plate optimization technology, significantly suppressing fluid pulsations and structural vibrations to meet modern factory noise standards.

• Robust Through-Drive Capability: Supports tandem mounting of secondary piston or internal gear pumps, streamlining the power integration of complex multi-actuator systems.
