Rexroth A10VSO Series Pump | A10VSO18, A10VSO28, A10VSO10 | Variable Piston Pump

Rexroth A10VSO Series Industrial Axial Piston Variable Pump

Product Overview: The Rexroth A10VSO series is the cornerstone of global open-circuit industrial hydraulic systems. This series is widely utilized in metal-cutting machine tools, presses, injection molding equipment, and various industrial power units (HPUs). From the ultra-compact A10VSO10 to the classic A10VSO18/28, these pumps are renowned for their exceptional pressure control precision, low-noise operation, and high power density. Core models like the A10VSO28DFR1 utilize advanced load-sensing technology to ensure high-efficiency operations while maximizing energy savings.

Key Technical Advantages:

• Diverse Control Logic (DR/DFR): The A10VSO10DR/52R-PPA14N00 features Pressure Control (DR) for constant system pressure. The A10VSO18DFR1/31R-PPA12N00 is equipped with Pressure/Flow Compensator Control (DFR1), modulating flow instantaneously based on load demand to drastically reduce system heat.

• Multi-Generation Design (Series 31 & 52): We offer both the classic Series 31 (e.g., A10VSO18/28) and the more compact Series 52 (e.g., A10VSO10). Series 52 is optimized for space-constrained equipment while maintaining Rexroth’s high-performance standards.

• Superior Quiet Performance: Acoustically optimized housing designs ensure noise levels remain well below industry averages even at 280 Bar, meeting the environmental requirements of modern green factories.

• Thru-Drive & Double Pump Expansion: The thru-drive capability allows for easy mounting of a second pump to form a Double Pump assembly, significantly enhancing hydraulic system integration and flexibility.
