Product Description
Rexroth A11VO Series 145cc High-Pressure Variable Piston Pumps
Product Overview: The Rexroth A11VO series is a high-performance axial piston variable displacement pump engineered specifically for heavy-duty open-circuit mobile machinery. As the flagship displacement of the series, the 145 cm³/rev specification is the premier choice for large-scale cranes, rotary drilling rigs, and concrete pump trucks due to its exceptional power density. Featured models like the A11VO145LRDS/11R-NZD12K83 and A11VO145LRDS/11R-NZD12N00 integrate the precision LRDS (Power, Pressure, and Load Sensing) regulator. These pumps operate continuously at a rated pressure of 350 Bar, demonstrating superior structural stability even under severe instantaneous shock loads.
Key Technical Advantages:
Versatile LRDS Regulator: Integrates Power Control (L), Pressure Cut-off (D), and Load Sensing (S). This triple-function modulation perfectly matches the engine’s power curve, minimizing energy waste and significantly enhancing fuel efficiency.
Compact Series 11 Architecture: The optimized swashplate design offers a superior power-to-weight ratio, facilitating easier installation within the tight engine compartments of construction machinery.
Extreme High-Pressure Durability: Rated for continuous operation at 350 Bar (5100 PSI) with peak capabilities up to 400 Bar. Built with reinforced rotating groups and high-strength housings for 24/7 reliability.
Superior Suction & High-Speed Efficiency: Streamlined inlet designs and optimized valve plates enhance self-priming capability, maintaining peak volumetric efficiency even at high RPMs.
100% Through-Drive Capability: Supports full-torque through-drive for tandem mounting of auxiliary pumps, simplifying the layout of complex multi-circuit hydraulic systems.
Detailed Models & Parameters:
Core Series: Rexroth A11VO Series 11 (Open Circuit).
