Rexroth A10VO A10VSO Pump | A10VO28DFR1, A10VO45DFR1 | 10-140cc | Axial Piston Variable Pump

Rexroth A10VO & A10VSO Series Efficient Variable Axial Piston Pump

Product Overview: The Rexroth A10VO (Mobile) and A10VSO (Industrial) series represent the global benchmark for axial piston variable displacement pumps. Utilizing a swashplate design, this series covers a comprehensive range of displacements from 10 to 140 cm³/rev. Flagship models such as the A10VO28DFR1/31R-VSC62K68 and A10VO45DFR1/31R-PSC62K01 are integrated with precision Load Sensing (DFR1) mechanisms. Its primary strength lies in providing real-time flow and pressure adjustments based on system demand, delivering peak energy efficiency for injection molding machines, material handling, construction equipment, and various industrial power units.

Key Technical Advantages:

• DFR1 Load Sensing Control: * DFR1 Logic: This mechanism senses the pressure requirements of the actuators and automatically modulates the swashplate angle. During standby or light-load conditions, the pump minimizes output, drastically reducing fuel consumption and heat generation.

• Exceptional Noise & Vibration Control: Optimized nine-piston rotating groups combined with high-strength damped housings ensure quiet operation even at rated pressures of 280 Bar, improving cabin and factory environments.

• Compact Power Density: The A10VO28/45 specs are optimized for restricted envelopes, delivering high-pressure power while maintaining a minimal footprint for easy integration.

• 100% OEM-Standard Interchangability: Manufactured to strict Rexroth Series 31 mounting standards (e.g., VSC62K68 specs), ensuring spline shafts, mounting flanges, and porting align perfectly with original equipment.

• Wear & Contamination Resistance: Critical rotating components (pistons, cylinders, and valve plates) undergo specialized hardening to withstand continuous high-duty cycles in harsh job site conditions, extending total service life.
