Rexroth A10VSO & A10VO Series Load Sensing Variable Piston Pumps

Product Overview: The Rexroth A10V series variable displacement piston pumps are pivotal components in global industrial automation and mobile hydraulic systems. This range includes the A10VSO (Series 31) for industrial stationary applications and the A10VO (Series 52) optimized for compact machinery. Key models feature the ultra-compact 10cc (A10VSO10) and the mid-range 28cc (A10VSO28). Utilizing advanced DFR/DFR1 (Load Sensing) control logic, these pumps sense the real-time flow demands of actuators and provide precise matching output, effectively preventing excess heat generation and significantly reducing energy consumption. They are the premier choice for automated production lines, machine tool cooling, compact hydraulic balers, and agricultural steering systems.

Key Technical Advantages:

• Intelligent Load Sensing (DFR/DFR1): Equipped with high-precision compensator valves for dual pressure and flow regulation, ensuring exceptional response sensitivity even under complex duty cycles.

• Low-Noise Operational Design: Fluid-dynamically optimized housing and 9-piston rotating groups ensure minimal pressure ripple at standard 1500 rpm operations.

• Compact & High-Strength Architecture: Built with lightweight yet robust materials, these pumps maintain a 280 Bar rating while offering superior installation flexibility in confined spaces.

• Minimal Energy Losses: During standby or low-flow demand, the pump rapidly swivels to minimum displacement, drastically boosting the overall energy efficiency of the machine.

• Global Standard Versatility: Features standard SAE mounting flanges and shaft specifications, supporting versatile through-drive options for multi-pump configurations.
