REXROTH A11VLO Series Variable Displacement Axial Piston Pumps |
Product Description |
The A11VLO series is a high-performance swashplate-type variable displacement pump designed for open-circuit hydraulic systems. It is widely used in mobile and industrial applications, including construction machinery, cranes, and concrete pumps, due to its high efficiency, precise control, and robust design. |
Key Features |
1. High Pressure & Efficiency |
◦ Rated pressure: 350 bar (peak 400 bar), with an upgraded 450-bar version (A11VLO/1x-H) for extreme loads. |
◦ Energy savings up to 30% via stepless flow adjustment and load-sensing control, reducing partial-load waste. |
2. Advanced Control Options |
◦ Supports multiple control mechanisms: |
▪ LR (Constant Power): Maintains stable power output under varying loads. |
▪ LRDS (Electronic Proportional Control): Adjusts displacement via 24V signals (200–600mA). |
▪ Pressure Cutoff & Load Sensing: Automatically limits pressure or matches flow to demand. |
3. Integrated Boost Pump |
◦ Unique centrifugal boost pump design (marked "L" in model codes) enhances suction performance, enabling higher speeds (up to 2,600 rpm) and compact installations in space-constrained applications (e.g., offshore piling). |
4. Durable Construction |
◦ High-strength cast iron housing and hardened friction pairs (e.g., pistons, swashplate) for extended lifespan. |
◦ 100% through-drive capability: Allows串联 connection with gear pumps or additional piston pumps. |

FAQ:
Rexroth A11VLO190 FAQ
1. What is the Rexroth A11VLO190?
• Answer: The A11VLO190 is an axial piston variable displacement pump designed for open-circuit hydraulic systems. It features a swashplate design, adjustable flow control (0 to max output), and is widely used in mobile hydraulics (e.g., dump trucks, construction machinery) and industrial applications.
2. What are the key specifications?
• Displacement: 193 cm³/rev (max).
• Pressure: 350 bar (nominal), 400 bar (max).
• Speed: Up to 2,500 rpm (at Vg max).
• Flow Rate: 483 L/min (at nominal speed).
• Power Output: 281 kW (at 350 bar).
• Weight: ~104 kg.
3. What control options are available?
• Standard Controls:
◦ LR: Power control.
◦ LRDU2: Hydraulic remote control.
◦ EP2D: Electronic proportional control.
• Optional Controls: Load sensing (LS), pressure cutoff (DRS), cross-sensing (LRCS).
4. What are the compatible models or sizes?
• The A11VLO series includes sizes from 40 to 260 (e.g., A11VLO130, A11VLO145, A11VLO260). The A11VO series (110–280) is also related but optimized for higher power demands.
5. How is the pump installed and maintained?
• Installation:
◦ Ensure clean hydraulic fluid (NAS 1638 ≤9 grade recommended).
◦ Avoid axial force on the pump shaft during mounting.
◦ Use proper filtration (5–10 µm) for oil filling.
