Product Description
Rexroth A10VSO 45 Series Axial Piston Variable Displacement Pump
Product Overview: The Rexroth A10VSO 45 series is the global standard power source for open-circuit industrial hydraulic systems. Renowned for its proven swashplate design and exceptional reliability, this series is extensively used in metal-cutting machine tools, plastic processing machinery, woodworking equipment, and various industrial power units. Featured models such as the A10VSO 45 DR/31R-PPA12N00 (Pressure Control) and A10VSO 45 DFR/31R-PPA12N00 (Load Sensing/Flow Control) deliver precise power distribution, significantly reducing energy consumption and enhancing operational smoothness.
Key Technical Advantages:
Precision Control Mechanisms:
DR (Pressure Control): Automatically maintains preset system pressure. Upon reaching the setpoint, the pump reduces displacement to “zero flow” standby, maximizing energy efficiency.
DFR/DFR1 (Load Sensing): Modulates flow in real-time based on actual actuator demand, ensuring zero redundant heat generation.
Extended Industrial Service Life: Optimized for continuous operation at 280 Bar (4000 PSI). Features high-strength bearings and patented valve plate technology for heavy-duty cycles.
Low Noise & Low Pulsation: The optimized 9-piston rotating group effectively suppresses fluid pressure pulsations, drastically reducing mechanical operational noise.
100% Industrial OEM Compatibility: Manufactured to strict Rexroth Series 31 standards (e.g., PPA12N00 end cover), ensuring flanges, keyed shafts, and port positions align perfectly for “drop-in” replacement.
Through-Drive Capability: Supports tandem mounting of auxiliary pumps via the through-drive, facilitating integration into complex multi-circuit hydraulic systems.
Detailed Models & Parameters:
Core Series: Rexroth A10VSO Series 31.
Displacement: 45 cm³/rev.
Representative Models: A10VSO 45 DR/31R, A10VSO 45 DFR/31R, A10VSO 45 DFR1/31R.
Pressure Ratings: Rated at 280 Bar (4000 PSI); Intermittent peak support up to 350 Bar.
Housing: High-strength cast iron.
Target Applications: CNC machine tool power units, injection molding, small presses, paper machinery, and hydraulic lift platforms.
