Product Overview
▔▔The Rexroth A11VG Series is a high-performance axial piston variable displacement pump designed specifically for hydrostatic closed-circuit drives. Operating with a swashplate design, it delivers exceptional volumetric efficiency, high power density, and outstanding reliability under extreme working conditions. It is widely recognized across industrial and mobile hydraulics as a industry-standard solution for heavy-duty transmission applications.
Key Advantages
▔▔-
High Power-to-Weight Ratio: Compact design delivering high displacement and pressure output in a space-saving footprint.
Closed-Circuit Optimization: Engineered specifically for closed-loop hydrostatic drives, featuring integrated boost pumps and high-pressure relief valves.
Versatile Control Options: Compatible with a broad variety of control devices, including mechanical, hydraulic, and modern electro-proportional controls.
Through-Drive Capability: Supports auxiliary pumps (such as gear pumps or secondary piston pumps) for multi-circuit systems.
High Operating Pressure: Continuous working pressure up to 400 bar (5800 psi) and peak pressure capabilities up to 450 bar (6500 psi).
Low Operating Noise: Optimized swashplate and fluid port design minimize acoustic radiation during high-load operation.

FAQ
▔▔Q1: What is the main difference between closed-circuit (A11VG) and open-circuit (A11VO) Rexroth pumps?
A: The A11VG is designed for closed-circuit systems, where fluid returns directly from the motor to the pump inlet without passing through a main reservoir. It features twin high-pressure ports and an integrated boost pump. The A11VO is engineered for open-circuit systems, pulling oil from an open reservoir and discharging through a directional control valve.
Q3: Why does a Rexroth A11VG pump require a charge (boost) pump?
A: In a closed-loop system, minor fluid losses occur due to internal component lubrication and flushing valves. The integrated charge pump supplies low-pressure oil to prevent cavitation in the low-pressure leg of the loop, cools the system, and supplies control pressure for the pump swashplate actuators.
