Rexroth A11VO190 A11VO75 Hydraulic Pump | A11VO190LRDS/11R-NZD12N00-S

Model Number	A11V0190LRDS/11R-NZD12N00-S, Seal kits, A11VO190LRDS/11R-NZD12N00-S

Product Description

LIC Hydraulic specializes in the Rexroth A11VO Series, a premier range of axial piston variable displacement pumps designed for high-pressure open circuit applications. Engineered to withstand continuous operating pressures up to $350\text{ bar}$ ( $5000\text{ PSI}$ ), the A11VO series (including A11VO75 and A11VO190) is the gold standard for heavy-duty mobile machinery. The specific configuration A11VO190LRDS/11R-NZD12N00-S features a highly sophisticated LRDS control system, providing the perfect balance of power management, pressure limiting, and load-sensing efficiency to maximize machine productivity and minimize energy waste.

Technical Specifications (Bulleted List)

Series: Rexroth A11VO (Open Circuit)
Displacements: $40, 60, 75, 95, 130, 145, 190, 260\text{ cc/rev}$
Max Pressure: Continuous $350\text{ bar}$ , Intermittent $400\text{ bar}$ .
Control Options: LR (Power), D (Pressure Cut-off), S (Load Sensing), E (Electronic).
Swash Plate Design: Compact and highly responsive for dynamic load cycles.
Efficiency: High volumetric and mechanical efficiency throughout the RPM range.

Key Technical Advantages

Intelligent Power Management: The LRDS controller ensures that the pump torque never exceeds the engine’s available torque, preventing stalls and optimizing fuel consumption.
Thru-Drive Capability: The “ZD12” thru-drive option allows for $100\%$ torque transfer, enabling the mounting of additional pumps on the same drive shaft.
Robust Service Life: Featuring heavy-duty bearings and optimized tribological interfaces, the A11VO is built to endure the harshest mining and construction environments.
Low Noise Emission: Precision-engineered internal dampening and swash plate geometry significantly reduce fluid-borne noise compared to previous generations.

Application Areas

Mining & Excavation: Main hydraulic drive for large excavators and rotary drilling rigs.
Material Handling: Primary power for mobile cranes and reach stackers.
Industrial Plants: High-power hydraulic stations for presses and forging equipment.

Expert Maintenance Tips

Filter Precision: For high-pressure pumps like the A11VO, maintain an oil cleanliness of $ISO\text{ 18/16/13}$ . Contaminants in the LS control signal ports can cause hunting or failure to reach full stroke.
Case Drain Line: Ensure the case drain line is sized correctly to keep case pressure below $2\text{ bar}$ to protect the shaft seal.
System Priming: Always prime the pump case with clean oil before initial startup. A single second of dry operation at $2000\text{ RPM}$ can lead to catastrophic internal failure.
