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.
• Maintenance:
◦ Monitor for leaks (e.g., shaft seals, valve plate wear).
◦ Check for abnormal noise or overheating, which may indicate air ingress or bearing failure.
6. What are common failure modes?
• Issue: Pump reaches cutoff pressure immediately.
◦ Solution: Check X-port pressure or LS valve blockage.
• Issue: Low/no pressure output.
◦ Solution: Verify motor rotation, X-port feedback, or DR valve malfunction.
• Issue: Excessive noise/heat.
◦ Solution: Inspect for air in the system or bearing damage.
7. Where can I buy replacement parts or repair services?
• Parts: Valve plates, piston shoes, seals, and rotating groups are available from OEM suppliers or aftermarket providers (e.g., Ningbo Yineng Hydraulics).
• Repair: Specialized workshops offer rebuilds with original-grade components.
8. What is the delivery time and MOQ?
• MOQ: 1 unit (custom branding available).
• Delivery: 2–3 days (in stock) or 7–15 days (custom orders).
9. How does the A11VLO190 differ from the A11VO series?
• A11VLO: Standard for mobile hydraulics (350/400 bar).
• A11VO: Optimized for higher pressures (up to 420 bar) and includes advanced controls like Hall-effect sensors.
10. What hydraulic fluid is recommended?
• Use mineral oils or compatible fluids (NAS 1638 ≤9 grade). For HFA/HFB fluids, consult Rexroth technical sheets (RE 90220/90221).
