Product Overview The Rexroth A11VLO130 Variable Pump is the powerhouse behind some of the most demanding mobile machinery in the world. Its flow is proportional to the drive speed and displacement, capable of seamless adjustment by modulating the swashplate angle. The unique internal impeller acts as a centrifugal centrifugal boost pump, effectively eliminating cavitation risks even when driven directly by high-revving diesel engines.
Why Choose the Rexroth A11VLO Series?
-
High-Speed Capability: The built-in impeller significantly improves suction characteristics, allowing the pump to operate at speeds far exceeding standard open-circuit pumps.
-
Remote Pressure Control (DRG): The DRG control module allows the maximum system pressure to be adjusted remotely via a pilot valve, offering flexible and safe machine operation.
-
Power Dense & Robust: Rated for 350 bar continuous pressure, it features heavy-duty bearings and a reinforced swashplate to withstand severe shock loads.
-
Through-Drive Design: Capable of mounting additional pumps (like gear pumps or other piston pumps) directly to the rear flange, forming a compact multi-pump system (as indicated by the “K02” code).
