Rexroth A11VLO Series 190cc High-Pressure Variable Piston Pumps

Product Overview: The Rexroth A11VLO series is one of the most powerful heavy-duty axial piston variable displacement pumps designed for open-circuit mobile machinery. As the flagship displacement of Series 11, the 190 cm³/rev specification is engineered to meet the extreme power demands of large-scale construction equipment, such as all-terrain cranes, rotary drilling rigs, and heavy-duty concrete pumps. Featured models like the A11VLO190LRDS/11R-NSD12K01 and A11VLO190DRS/11L-NSD12N00 integrate advanced Power, Pressure, and Load Sensing (LS) control technologies. Operating at a rated pressure of 350 Bar, these pumps ensure precise flow output and superior energy efficiency under complex multi-actuator load conditions.

Key Technical Advantages:

• Intelligent Control Regulators: Supports LRDS (Power/Pressure/LS) and DRS (Pressure/LS) modulations. These systems automatically optimize pump displacement in real-time according to load demand, minimizing the risk of engine stalling and maximizing fuel savings.

• Optimized for Mobile Machinery: The compact swashplate design provides industry-leading power density, facilitating easier installation within the tight engine compartments of large construction vehicles.

• Rugged Heavy-Duty Construction: Rated for continuous operation at 350 Bar (5100 PSI) with peak capability up to 400 Bar. Built with reinforced rotating groups and high-strength housings to withstand high-dust and high-impact mining/construction environments.

• Superior Suction & RPM Performance: Streamlined internal fluid paths ensure excellent suction efficiency at rated speeds, maintaining stable performance during cold starts or high-altitude operations.

• 100% Through-Drive Capability: Supports full-torque through-drive for tandem mounting of auxiliary pumps, simplifying the integration of multi-circuit hydraulic layouts.
