Product Description
Rexroth A11VO190 Series Heavy-Duty Axial Piston Variable Pump
Product Overview: The Rexroth A11VO190 series is a high-performance swashplate-type axial piston variable pump engineered for Open Circuit high-pressure hydraulic systems. As a core large-displacement model (190cc) within the A11V family, the A11VO190 is renowned for its exceptional power density and stability under extreme shock loads. Offering options from traditional LRDH1 mechanical power control to advanced LE2S2 electronic proportional control, this series ensures a precise match between hydraulic output and both engine power and automated load demands.
Key Technical Advantages:
Advanced Digital Control (LE2S2): The A11VO190LE2S2/11R-NZG12N00P-S model features electronic proportional stroke control with integrated pressure sensing. It enables seamless, stepless digital modulation, making it the ideal power source for modern intelligent hydraulic systems.
Intelligent Power Regulation (LRDH1): The A11VO190LRDH1/11R-NZD12K83 model utilizes a precision regulator that integrates constant power control, pressure cut-off, and hydraulic pilot adjustment to dynamically balance system pressure and displacement, preventing engine stalls.
Heavy-Duty High-Pressure Performance: Built for grueling environments, the A11VO190 supports a rated pressure of 350 Bar and peak cycles up to 400 Bar. Reinforced swashplate supports maintain peak volumetric efficiency under continuous heavy-duty load cycles.
Robust Thru-Drive Capability (K83): Features powerful thru-drive functionality. The K83 suffix indicates support for tandem mounting secondary pumps, simplifying power distribution for multi-circuit hydraulic designs.
