Rexroth A10VSO Series Pump | A10VSO140 DFR1, A10VSO100 DR | 280 Bar High Pressure Piston Pump

Rexroth A10VSO Series (Series 31) & Equivalent High-Pressure Variable Piston Pump

Product Overview: Our range features premium original and high-quality equivalent Rexroth A10VSO series variable displacement pumps, specifically highlighting the core heavy-duty displacements: 100cc (A10VSO100) and 140cc (A10VSO140). As integral members of the Series 31, these pumps are engineered for Open Circuit systems with a rated operating pressure of 280 Bar. Utilizing precise control logics such as DFR1 (Load Sensing) and DR (Pressure Control), they accurately match flow and pressure to system demands, serving as the efficient heart of injection molding machines, die-casting equipment, and industrial Hydraulic Power Units (HPUs).

Key Technical Advantages:

• Advanced Control Modulations (DFR1/DR):

  • DFR1 Load Sensing (A10VSO140DFR1): Dual pressure and flow compensation ensures the system consumes only the power strictly required, drastically boosting overall fuel or electrical efficiency.

  • DR Pressure Regulator (A10VSO100DR): Automatically de-strokes the pump to minimum displacement upon reaching target pressure, ideal for pressure-holding phases and heat reduction.

• Heavy-Duty Industrial Reliability: Rated for a continuous operating pressure of 280 Bar (28 MPa) with peak capabilities reaching 350 Bar. Features reinforced rotating groups and hydrostatically balanced swashplates for extended life in harsh environments.

• Flexible Rotation & Shaft Configurations:

  • 31L (Left-hand/CCW): Models like A10VSO140DFR1/31L cater to specific tandem pump requirements or specialized drive-end rotation needs.

  • 31R (Right-hand/CW): Standard industrial configuration ensuring seamless coupling with mainstream electric motors.

• Quiet & Low Pulsation: Acoustically optimized housing and patented valve plate technology maintain exceptionally low mechanical noise even at full operating pressure.

• Full Interchangeability: Mounting dimensions, porting, and performance curves strictly adhere to international standards, allowing for direct replacement of original A10VSO units while reducing maintenance overhead.
