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 large-scale mobile machinery, mining rigs, and industrial presses. Advanced configurations like EP2Z electro-hydraulic proportional control and LRH2 power control ensure a precise match between hydraulic power output and complex operational demands.
Key Technical Advantages:
Precise Digital Modulation (EP2Z): The A11VO190EP2Z/11R-NSD12K17H-S (R902217589) model features state-of-the-art electro-hydraulic proportional stroke control (EP2Z). This allows for remote, stepless adjustment of pump displacement via an electronic controller, enabling high-efficiency feedback control in automated systems.
Intelligent Power Regulation (LRH2): The A11VO190LRH2/11R-NPD12N00 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 (K17H): Features powerful thru-drive functionality. The K17H suffix indicates support for tandem mounting secondary pumps, simplifying multi-circuit power distribution and optimizing system footprint.
