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. |

*Values are theoretical; actual performance depends on system conditions. |
Applications |
• Construction: Pile drivers, concrete pump trucks, excavators. |
• Mobile Hydraulics: Cranes, road pavers, and agricultural machinery. |
• Industrial Automation: Presses, plastic injection molding. |
Common Models & Configurations |
• A11VLO145LRDS/11R-NZD12K83: Constant power + pressure cutoff. |
• A11VLO190LRDU2: Electronic proportional control (24V). |
• A11VLO260DRS: Basic pressure-compensated control. |
Maintenance & Installation Notes |
• Critical Requirements: |
◦ Suction pressure must not exceed 2 bar (absolute). |
◦ Pre-fill boost pump casing with fluid before startup. |
• Avoid: |
◦ Low oil levels, contaminated fluid, or excessive backpressure (>0.2 bar). |
Advantages Over Competitors |
• Higher pressure tolerance (vs. standard A11VO series). |
• Lower noise and vibration due to optimized swashplate dynamics. |
• Modular controls for flexible system integration. |
Supplier & Pricing |
• OEM Suppliers: HBOETH (China), Partsdic® (replacement parts). |
• Pricing: Varies by model (e.g., A11VLO95 starts at ~$1,000; MOQ 1 unit). |
