Rexroth A10VSO & A10VO Pump | A10VSO18, A10VSO28, A10VSO45-140 | Variable Piston Pump

Rexroth A10VSO & A10VO Series Variable Displacement Piston Pumps

Product Overview: The Rexroth A10V series variable piston pumps are the cornerstone of modern hydraulic technology. We provide full-spectrum displacement support, including the A10VSO series for industrial power units and the A10VO series optimized for mobile machinery. Covering core sizes: 10, 18, 28, 45, 71, 74, 100, and 140cc. Featured models like the A10VSO18DFR/31R-PPA12N00 lead the market in reliability. Utilizing a proven swashplate design and flexible control options—such as DFR Load Sensing and DR Pressure Control—these pumps maximize energy efficiency while ensuring robust power delivery for CNC machine tools, plastic machinery, injection molding, mini excavators, and material handling equipment.

Key Technical Advantages:

• Comprehensive Displacement Range: From the ultra-compact 10cc to the heavy-duty 140cc, offering standardized mounting interfaces for easy integration across diverse load requirements.

• Intelligent Load Sensing (DFR/DFR1): Real-time matching of flow and pressure to actuator demand, minimizing overflow losses and significantly reducing hydraulic oil heat generation.

• High Pressure Performance: Rated for continuous operation at 280 Bar (4060 PSI) with peak capabilities up to 350 Bar (5100 PSI), ensuring high reliability under heavy duty cycles.

• Exceptional Low-Noise Design: Optimized 9-piston rotating groups suppress pressure ripples, making them ideal for indoor factory floors and noise-sensitive environments.

• Superior Power Density: Compact housing with integrated high-performance regulators supports through-drive options, facilitating multi-pump tandem configurations.
