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 large-displacement model (190cc) within the A11V family, the A11VO190 is renowned for its exceptional power density and stability under extreme shock loads. It is widely utilized in heavy mobile machinery, mining rigs, and large-scale industrial presses. Advanced configurations like EP4S electro-hydraulic proportional control and LRDH1 power control ensure a precise match between hydraulic power output and complex operational demands.
Key Technical Advantages:
Precise Digital Modulation (EP4S): The A11VO190EP4S/11R-NZD12K07H-S model features state-of-the-art electro-hydraulic proportional stroke control (EP4S). This allows for remote, stepless adjustment of pump displacement via an electronic signal, enabling high-efficiency feedback control in automated systems.
Intelligent Power Regulation (LRDH1): The A11VO190LRDH1/10R-NZD12K83 model utilizes a precision regulator integrating constant power control, pressure cut-off, and hydraulic pilot regulation. It dynamically matches engine power to prevent stalling and significantly reduce fuel consumption.
Superior High-Pressure Durability: Built for grueling environments, the A11VO190 supports a rated pressure of 350 Bar and peak cycles up to 400 Bar. Reinforced rotating groups and swashplate supports maintain peak volumetric efficiency under continuous heavy loads.
Robust Thru-Drive Capability (K07H/K83): Features powerful thru-drive functionality. The K07H suffix indicates support for tandem mounting secondary pumps, simplifying multi-circuit power distribution and optimizing system footprint.
