Product Description
Rexroth A10VSO Series (Series 31) Variable Plunger Pump for Injection Molding Machines
Product Overview: The Rexroth A10VSO series is the premier “power heart” for injection molding machines and industrial Open Circuit hydraulic systems. This series highlights the mainstream 71cc (A10VSO71) and high-capacity 140cc (A10VSO140) displacements. As a classic representative of the Series 31, A10VSO pumps are engineered specifically for heavy-duty industrial environments, delivering reliable performance under a rated pressure of 280 Bar. Through advanced DFR1 (Load Sensing) and DR (Pressure Control) modulations, these pumps provide precise energy matching for injection processes, drastically reducing energy waste and oil temperature.
Key Technical Advantages:
Optimized Process Control (DFR1/DR):
DFR1 Load Sensing (A10VSO71DFR1): Dual pressure and flow modulation delivers only the required power, optimizing energy efficiency during clamping and injection phases.
DR Pressure Regulator (A10VSO140DR): Automatically de-strokes the pump when target pressure is reached, ideal for pressure-holding phases in molding.
Heavy-Duty Industrial Reliability: Rated for an operating pressure of 280 Bar (28 MPa) with peak capabilities reaching 350 Bar. Reinforced rotating groups ensure an extended service life under 24/7 continuous duty cycles.
Superior Seal & Shaft Configurations:
VPB12 (A10VSO140): Features FKM (Viton) seals and a parallel keyed shaft, offering excellent high-temperature resistance and stable torque transmission.
PPA12 (A10VSO71): Equipped with NBR seals and a splined shaft, ensuring high-precision power coupling with electric motors.
Low Noise & Low Pulsation: Utilizing Rexroth’s patented swashplate noise-reduction technology, maintaining smooth and quiet operation even at full pressure, meeting modern green factory standards.
Compact Integration & Interchangeability: The compact Series 31 design offers extreme power density. The through-drive architecture supports tandem mounting, streamlining the layout of complex injection systems.
Detailed Models & Parameters:
Core Series: Rexroth A10VSO Series 31.
Representative Models: A10VSO140 DR/31R-VPB12N00, A10VSO71DFR1/31R-PPA12K01.
