I. Product Overview
The A10VO series represents Rexroth's medium-pressure range of swashplate-type axial piston pumps, featuring a nominal pressure of 280 bar and a peak pressure of up to 350 bar. These pumps are designed for open-circuit hydrostatic drives. By adjusting the angle of the rotating swashplate, they enable stepless variation of the flow rate. The series offers various control methods, including pressure control (DR/DRG), pressure and flow control (DFR/DFR1), pressure, flow, and power control (DFLR), and electrical control (ED/ER).
II. Specific Model Descriptions
1. A10VO45
• Displacement: 45 cm³/rev
• Maximum Flow Rate: For example, the A10VSO45DFR/31 model can achieve a maximum flow rate of 30.9 gpm (117 L/min).
• Applications: Widely used in construction machinery and industrial equipment, providing stable high-pressure hydraulic oil to hydraulic systems to drive lifting, excavation, rotation, and other actions.
• Features:
• Energy-efficient and durable design with low noise levels.
• Compared to fixed-displacement pumps, constant pressure/flow control can reduce energy consumption by over 30%.
• The swashplate bearing employs hydrostatic unloading technology, paired with FKM fluororubber seals for extended service life.
• Optimized suction structure and casing oil drain design reduce noise levels below those of similar products.
2. A10VO71
• Displacement: 71 cm³/rev
• Maximum Flow Rate: For example, the A10VSO71DFR/31 model can achieve a maximum flow rate of 41.2 gpm (156 L/min).
• Applications: Also widely used in construction machinery and industrial equipment, particularly suitable for applications requiring high-flow hydraulic oil.
• Features: Similar to the A10VO45, but with a larger displacement, enabling higher flow and power output.
3. A10VO100
• Displacement: 100 cm³/rev
• Applications: Suitable for large-scale construction machinery and industrial equipment requiring high-flow, high-pressure hydraulic oil.
• Features: Offers higher displacement and flow output capabilities to meet the hydraulic demands of large-scale equipment.
4. A10VO140
• Displacement: 140 cm³/rev
• Maximum Flow Rate: Up to 252 L/min
• Applications: Primarily used in industrial applications, such as heavy machinery and equipment, requiring high-pressure and high-flow performance.
• Features:
• Constructed with corrosion-resistant cast iron for durability in harsh industrial environments.
• Provides high output, high precision, continuous commercial reliability, and safety features compliant with ISO standards.
