| 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). |
